Please note that today's presentation includes information provided as of today, August 13th, 2026, and Valneva undertakes no obligation to revise or update forward-looking statements, except as required by applicable securities laws.

With that, it's my pleasure to introduce Thomas to begin today's presentation.

Thomas Lingelbach

Thank you so much, Josh. Good day, everyone.

Let me start off with a couple of introductory remarks. The first half of 2026 has certainly been marked on our effort to focus on enhancing our financial position, especially after the initial Lyme Phase 3 VALOR results and the resulting uncertainty.

We have been able to generate a strong cash position with more than €120 million in cash. This is a result of our disciplined cash management and the proceeds from the recent offering.

We also included a broad restructuring program, and we expect the positive P&L and cash flow impacts in the second half of this year and, of course, beyond. This included a reduction in our workforce, a reprioritization of projects, activities, and a focus on our core operational business.

When we look at our general commercial business performance, we generated more than €60 million in total product sales. We have reaffirmed the guidance because the half-year sales performance is in line with our anticipated phasing of product sales throughout the year 2026.

We have had a number of adverse EBIT impacts in the first half of the year. Peter will explain those in greater detail.

Most of them are really one-off effects and are nonrecurring. The most important thing and the most exciting thing is that Pfizer continued to be very positive about the prospects of the Lyme disease vaccine.

They recently announced during their earnings that they expect regulatory decisions for the Lyme disease vaccine candidate in the next 12 months, which is really great news. Now turning to our general business update, and of course, I would like to start with Lyme.

That the vaccine showed a very strong point efficacy greater than 70%, a very good safety profile, and as we discussed multiple times, we had a miss on the lower bound of the 95% confidence interval. However, we have to note that we see here with this product candidate a very significant, clinically meaningful efficacy, and we had also 95% confidence interval lower bound greater than 20% in the second prespecified analysis.

All of that, in combination with the huge unmet medical need, the totality of clinical evidence, and the fact that we really expect a positive health economic benefit for a potential prophylactic solution, increases our confidence in the future prospect of a potential Lyme vaccine. There is a huge unmet medical need.

We have discussed this many times in the past. The annual burden of disease is increasing, and we have been noting recently close to 500,000 cases in the United States.

Europe, numbers are kind of still significantly underreported because not all countries have respective surveillance systems, but certainly north of 100,000 cases every year. Some of them come along with very severe manifestations in the order of 10% to 30%, carditis, neuroborreliosis, arthritis, and unfortunately, 5% to 10% of cases continue to have persistent symptoms even following treatment.

As such, we really believe that VLA15, how it's called now, is a compelling opportunity in a highly underserved market. We could really leverage a first-mover advantage.

The perception around a need for Lyme vaccination is high. We have the only Lyme disease vaccine candidate in late-stage clinical development, and it could become, if licensed, the first potential Lyme vaccine in nearly 30 years.

The vaccine is based on a proven mode of action. We cover the 6 key serotypes prevalent in the Northern Hemisphere, and the technology is based on modern state-of-the-art recombinant protein technology.

We have a broad addressable population. At this point in time, we showed in the study results for people above 5 years of age.

I mentioned already that we see a growing disease burden, and of course, with global warming, the tick population across all the high-risk areas of Lyme disease are steadily increasing. We have an excellent partner, and there is a huge strategic fit with Pfizer's vaccine franchise, and hence, we anticipate a very attractive commercial prospect and dynamic.

All in all, we share Pfizer's positivity on the prospects of that vaccine, and we really hope that we can get this vaccine to licensure on both sides of the Atlantic. On IXCHIQ, as part of our overall restructuring process and also reprioritization of our key strategic focus areas, we shift more and more towards the IXCHIQ access in countries where there is highest risk for chikungunya infection, meaning primarily low- and middle-income countries, and we are currently executing on a significant number of post-marketing activities, all supported by our great partner CEPI.

We have a pilot vaccination campaign ongoing in Brazil. We have more than 50,000 people already vaccinated today.

These are adults 18 to 59 years of age. We have a study ongoing to confirm effectiveness and optimize description of the safety profile, which, of course, over time could potentially even lift the highly restrictive warnings, precautions, and other indications we have right now in our label for travel.

All of that, of course, to ensure greater access, and we are focusing a lot right now on expanding our network of manufacturing distribution partners in low- and middle-income countries, and we hope that we will be able to even announce something towards the latter part of the year. The locally manufactured vaccine in Brazil by our partner Butantan has now been approved and is expected to be incorporated into Brazil's public health system in the near future.

We in-licensed an interesting candidate against shigellosis. It's the most clinically advanced tetravalent Shigella vaccine candidate.

Right now, we are running 2 studies, 1 in infants, the other 1 in adults. 1 is an immunogenicity and safety study, the other 1 is a controlled human infection model study, pilot efficacy through human challenge.

We expect for both studies results in the coming months, and of course, based on the results, we will decide on the next development steps for that vaccine. Of course, there is still a significant market opportunity for shigellosis, especially given that it's the second-leading cause of fatal diarrheal disease and estimated with 165 million cases and 600,000 deaths annually, mostly, of course, in children in LMIC countries, but there is also a very interesting opportunity to, either in a stand-alone setting or in a combination vaccine setting, to work towards a broad-covering diarrheal vaccine for travelers.

With this short update on our core R&D activities and general business developments, I would like to hand over to Peter to provide you with the financial report.

Peter Bühler

Thank you, Thomas. First looking at product sales.

Product sales reached €64 million compared to €91 million in the first half of 2025. Sales, excluding third-party products, decreased by -18.3% versus prior year at constant currency.

This decrease was primarily due to product-specific effects, which I will discuss shortly. IXIARO sales reached €44 million compared to €54.7 million in the prior year's first half.

The year-over-year decrease primarily reflects the transition to a new distributor in Germany in January 2026, as well as product sales phasing, notably the timing of deliverables to the US Department of Defense. Shipments to the US Department of Defense in the first half of 2026 continued under the 1-year contract signed in January 2025.

We expect to sign a new contract in the coming months and begin recording sales under this new contract in the second half of the current fiscal year. Foreign currency fluctuation also had an adverse impact of €1.5 million on IXIARO sales during the first half of 2026.

DUKORAL sales reached €14.7 million compared to €17.4 million in the first half of 2025. Prior-year sales benefited from 1-time sales associated with the supply of DUKORAL doses to Mayotte in response to cholera outbreak.

In addition, sales in the first half of 2026 were adversely affected by the distributor transition in Germany in January 2026. Similar to the first quarter, existing inventory transferred from the previous distributor were sufficient to meet market demand during the period.

Furthermore, there was a slight weakening of the travel market in certain geographies due to geopolitical factors. IXCHIQ sales reached €4.4 million compared to €7.5 million in the first half of 2025.

While current-year sales include the first shipment of drug substance to our Brazilian partner, Instituto Butantan, the prior year benefited from 40,000 doses sold to the French island La Réunion in response to a major chikungunya outbreak, as well as travel sales in the United States. In light of the slow product uptake in travel, the company is currently evaluating its future commercial strategy for IXCHIQ, including a potential focus on the endemic markets.

Third-party products decreased substantially from €11.4 million in the first half of 2025 to €1 million in the first 6 months of 2026. This planned reduction is the result of the key third-party distribution agreements that ended in December 2025 without renewal.

Moving on to the income statement on the next slide. Total revenues reached €65.8 million versus €97.6 million in the first half-year of 2025.

The decrease is mostly related to the lower product sales. Last year's other revenues also included a one-off upfront payment related to the licensing agreement with the Serum Institute of India for our single-shot chikungunya vaccine.

Looking at expenses. Cost of goods and services for the first half of 2026 reached €59.5 million compared to €47.2 million during the same period last year.

Cost of goods in the first half of 2026 were impacted by a number of nonrecurring and exceptional effects. In particular, a provision of €9.7 million in cancellation fees related to external manufacturing commitments for IXCHIQ and a €4.5 million non-cash impairment of excess IXCHIQ inventory resulting from lower than anticipated sales.

In addition, cost of goods were adversely impacted by changes in manufacturing schedule and volumes and related adverse variances, as well as higher idle costs following the transfer of manufacturing to our Almeida facility. IXIARO gross margin reached 56.4% compared to 65.5% in the prior year.

The decrease is mainly related to lower volumes and an unfavorable change in the manufacturing schedule. Last year's IXIARO gross margin was exceptionally high due to high manufacturing volumes and related favorable overhead absorption.

DUKORAL generated a gross margin of 24.7% compared to 52.9% in the first half of 2025. The gross margin of DUKORAL in the first half of 2026 was adversely impacted by higher than usual failed batch costs and inventory revaluation.

In contrast, the prior-year gross margin benefited from a favorable overhead absorption due to manufacturing timing and higher volumes. The IXCHIQ gross margin was negative due to the 1-time cancellation fees provisioned in the second quarter, as well as the inventory write-down mentioned previously, which importantly had no cash impact.

Research and development expense decreased from €32.4 million in the first half of 2025 to €30.2 million in the first half of 2026. That decrease is mainly the result of reprioritization and rescheduling of R&D activities.

Marketing and distribution expenses decreased significantly from €20.3 million in the prior year to €13.5 million in the first half of 2026. The decrease is related to a planned reduction in advertising and promotion related to IXCHIQ, as well as reduced personnel, warehousing, and distribution costs.

G&A expenses decreased to €15.4 million compared to €19 million in the first half of 2025. The reduction was a result of lower personnel costs and savings in advisory and professional services.

The company implemented the restructuring program in June 2026, and operating expenses in the first half-year include a 1-time cost of €3.2 million related to that program. Savings are expected in the second half-year and beyond.

In the first half of 2026, Valneva reported an operating loss of €49.9 million compared to €16.8 million in the prior year. Adjusted EBITDA loss in the first half of 2026 reached €40.1 million compared to €6 million in the prior year.

Before moving to the outlook and guidance, a word on cash. As mentioned by Thomas at the beginning of the call, cash at June 30th was €121.5 million compared to €109.6 million at the end of fiscal year 2025.

Cash used in operations in the first half of 2026 was €13.7 million compared to €10.9 million in the first half of the prior year. Now moving to the next slide, to slide 18.

We confirm our financial guidance for the fiscal year 2026, with product sales of €135 to €150 million and total revenues of €145 to €160 million. We expect the signing of a new contract with the US Department of Defense for the supply of IXIARO in the coming months.

We expect our commercial business to continue generating positive cash flow, and the restructuring program implemented in June will have a positive impact on the P&L and cash flow in the second half of the current fiscal year and beyond. We expect product-related gross margin to improve in the second half following the nonrecurring effects in the first half of the year.

We continue to see potential to become financially self-sustainable starting in 2026, pending successful regulatory approval of the Lyme disease vaccine and subsequent commercialization by Pfizer. With this, I hand the call back to Thomas.

Thomas Lingelbach

Thank you so much, Peter. Peter said 2026, we mean 2027, of course.

Also, it would be nice to be already in 2026 financially self-sustainable. Let me close by giving a little bit a prospect on how we see the future of Valneva, of course, provided and subject to Lyme success.

Going forward, we would really like to leverage the company's core strengths in vaccine development to deliver greater long-term value. We would like to build scale in the R&D pipeline once Lyme has been out of pipeline and, hopefully, successfully brought to market.

We see here a clear opportunity for strategic in-licensing to augment our clinical-stage pipeline, and what we would like to do is really to create a risk-balanced portfolio of innovative specialty, life cycle, and high-value vaccine assets, which are attractive and go very much beyond our prior focus on vector-borne diseases. We are working with the team to target new assets based on defined criteria and new targeted disease areas.

In parallel, we are advancing our internal earlier-stage candidates, such as EBV or ETEC stroke a broader enteric disease covering candidate program. We would like to put also emphasis on focusing on reducing antimicrobial resistance targets.

All of that will be flanked by further optimizing our integrated operations. We have kicked off a number of initiatives already as part of our restructuring program this year, and this mainly focuses on adapting and adjusting our value chain, chains of custody, make versus buy, external manufacturing partners, but also a continuous focus on optimizing our commercial models, all of that with 1 clear objective, namely to maximize cash from our integrated operations and commercial business in particular.

All in all, we see a very nice prospect for Valneva going forward, but for now, really, it's all about Lyme, and we have to wait until we hopefully see further positive developments on the Lyme vaccine candidate while executing solidly on our base business and continue our focus on strong cash management and disciplined cash management. With that, I would like to conclude the presentation and hand back to the operator to take your questions.

Operator

Thank you. To ask a question, you will need to press *11 on your telephone and wait for your name to be announced.

To withdraw your question, please press *11 again. One moment for our first question.

This question comes from Tara Bancroft from TD Cowen. Please go ahead.

Tara Bancroft

Hi, good morning, everyone. Thanks for hosting this call and taking our questions.

I was hoping maybe you could give us any more detail or thoughts or feelings that you have on a regulatory update? I know Pfizer still sounds optimistic about it and a decision in the near to mid-term over the next 12 months.

Is there anything else that you can add to the discourse that you've had with Pfizer and or regulators? That would be really appreciated.

Thanks.

Thomas Lingelbach

Pfizer are making very good progress with the regulatory agencies, and we hope that we will be able to announce next steps soon. That's all we can say at this moment in time specifically.

Tara Bancroft

I see. Okay.

Then maybe totally understood on that kind of commentary. Maybe then I can ask a little bit more detail about some of the scenarios that could possibly come up.

One in particular that might be really helpful to get your thoughts on is the potential for you and Pfizer to maybe run another Phase 3 program or even a post-marketing surveillance study. What I'm hoping you can help us understand is maybe the economics of those avenues, like what you would be responsible for, and how does that factor into your capital allocation plans?

Thanks.

Thomas Lingelbach

Yeah. It's a good question, Tara.

The existing agreement with Pfizer includes that Valneva is sharing development costs to licensure. Everything that comes beyond licensure is currently not part of the contractual agreements with Pfizer.

Whether or not we will further invest in Lyme on the points you mentioned is something that may be discussed at a later point in time, but definitely not before we see the product hopefully being licensed in the respective jurisdictions.

Tara Bancroft

Great. Thanks so much.

Operator

Thank you. We are now going to take our next question.

This one comes from Maury Raycroft from Jefferies. Please go ahead.

Maury Raycroft

Hi. Congrats on the progress, and thanks for taking my questions.

I was going to ask one on Shigella. Wondering if you can provide more color on what is gating the update.

Is it operational related to the clinical study or data analysis, or are you awaiting additional regulatory clarity on the potential development path? Then when the data are disclosed, should we also expect clarity on the path forward, and what are the latest scenarios that you're considering there?

Thomas Lingelbach

Yeah. Thanks for your question, Maury.

We have had a few delays on the program. That the studies are still conducted by LimmaTech.

LimmaTech recently got acquired by Dexcel. There are a couple of key clean-up steps right now, but we are in the last and final steps on data validation and putting the conclusions together, final analysis, etc.

This is not going to take a long time until we will be able to disclose. Now what do we expect?

Please remember what we said at the very beginning. We like the fact that we run a controlled human infection model, meaning a human challenge, and the human challenge will give us a very clear understanding about the efficacy of the vaccine.

Of course, it cannot be decisive or conclusive, but it's highly indicative. It will also provide us with a view on what is the immunological threshold that we need to achieve to see a level of protection and at which level of protection.

The flanking immunogenicity study in children will clearly provide us, A, with safety, which is very important, and it will also give us the first feel for how is the immunological profile in children as compared to adults, and of course, although it's not a direct head-to-head comparison possible, but it will also provide us with a good indication. We will take those 2 data packages together, and then we will see whether this is already good enough to proceed to the next development stage, or if there is a need to optimize, and this could be an optimization on dose, schedule, formulation, but our objective is to announce the next development steps either with the data or very shortly thereafter.

Hope this answered your question.

Maury Raycroft

That's helpful. Do you need some regulatory feedback to do that then, or

Thomas Lingelbach

Say it again?

Maury Raycroft

Do you need some regulatory feedback to

Thomas Lingelbach

We have a group of regulatory advisors with whom we are working. We are currently not expecting to seek a direct regulatory advice from the relevant regulatory bodies, because we had prior discussions, and I think for us it's pretty clear what the potential expectations would look like.

Maury Raycroft

Got it. Okay.

Maybe just one quick one for Lyme. I know you can't say a whole lot about where Pfizer's at with the process, but I'm just wondering for the US regulatory path versus the European regulatory path, can you say if those are both moving in parallel or is it more sequential where you want some clarity from the US before you can do an update for European status?

Thomas Lingelbach

I think both activities are progressing very nicely. These are 2 independent processes, and there is at this moment in time, I would assume that Europe probably goes first, but Pfizer is working closely with the FDA in support of its planned BLA submission for the Lyme disease vaccine candidate.

Maury Raycroft

Got it. Okay.

Thank you for taking my questions.

Operator

Thank you. We are now going to move to our next question.

This question comes from the line of Vamil Divan from Guggenheim Securities. Please go ahead.

Hey, guys. Good morning.

This is Edward on for Vamil. Just maybe a couple more questions on Lyme, if I may.

First, it sounds like Pfizer told us that they have filed in Europe, but not yet with the FDA, they're still in conversation. I'm wondering if you can share any details on your learnings or on why they decided to proceed that way?

Then the second question is, are there any differences in how the European agency and the FDA look at vaccine data in general and VLA15 specifically that you can kind of highlight for us that would be pertinent here? Then maybe to what extent the European filing do you think that would de-risk actually the FDA filing?

Thanks.

Thomas Lingelbach

Yeah. Yes, we can confirm that Pfizer filed with the European Medicines Agency.

They disclosed that to analysts after their last earnings. As such, we are of course very happy about this step.

As I mentioned, following the data, they clearly advanced the regulatory processes. As I mentioned earlier, these are 2 independent agencies.

Also, we know from the past and our own history that there are of course close interactions and communications in between those agencies. I would not speculate right now about why one earlier, the other later.

I would say let's celebrate this progress, and as we said in the past many, many times, there is a huge medical need on both sides of the Atlantic. There is a significant commercial opportunity on both sides of the Atlantic.

In one of the recent analyst reports, it was clearly articulated that the market is expected to be probably the same size, which is what we have been stating for years as it being the Valneva expectations. As such, we are quite pleased about progress, and as I said, we are looking forward to how Pfizer are going to conclude with the FDA in support of their planned BLA submission for the Lyme disease vaccine candidate.

Thanks. Maybe just how your understanding of how European versus FDA regulators look at sort of the vaccine data, and maybe VLA15, if there's anything we should be aware of and just how these 2 different agencies approach the data and what the bar is, how they think about the efficacy safety bar there?

Thomas Lingelbach

I don't know specifically how whether there are any differences in how they're going to look at the data. The data are what the data are, right?

We have safety data, we have efficacy data, we have immunogenicity data, and the data are the same. Of course, all agencies, and this is not Lyme-specific, and I say this as someone who has been now in vaccine development for more than 30 years, they all look at the same.

They look at the totality of clinical evidence, they look at at, risk-benefit, health economic benefits, underlying modes of action, scientific fundamentals. I'm I'm not necessarily assuming that they look differently at the data.

There are nuances, and we know it from, for example, our tick vaccine, which was the last vaccine that we brought from bench to licensure, that of course, when it comes to details on statistical analysis, on to details on potential post-marketing commitments or post-marketing pediatric development routes, there are slight differences here and there, but I have never seen in my history that there were, material differences in how the 2 regulatory bodies decided we're handling applications.

Great. Thank you so much.

Operator

Thank you. We are now going to take our next question.

This one comes from Suzanne van Voorthuizen from Kempen. Please go ahead.

Suzanne van Voorthuizen

Hi, team. This is Suzanne.

Thanks for taking my questions. I have one on the Valneva ambition from here.

It seems like that you are gravitating to more R&D or biotech-driven identity rather than a commercial focus. Can you elaborate to what extent this strategic direction depends on Lyme being successful, or phrased differently, how do you envision to walk this future path independent of the fate of the Lyme program?

Then I have a small question on the sale of the site in France. Next to the €6 million in proceeds, does this also bring an ongoing cost reduction of a certain degree?

Thank you.

Thomas Lingelbach

Hi, Suzanne. Yeah.

You are absolutely right that we have always seen, and we see our commercial business in a way being subscale, right? It is important to have a fully integrated model because the capabilities that we have on the commercial side, on the industrial side, are clearly beneficial for the vaccine development, and we have seen this across many, many different programs.

As such, we see a value in staying fully integrated. At the same time, the key purpose of our commercial business is not to focus on top-line growth or augmenting strategically.

At the end of the day, we would like to take the cash out of our commercial business and reinvest it in R&D, and therefore, our focus will be really to maximize cash generation from the commercial business going forward. We believe we are one of the very, very few remaining pure-play vaccine companies that have a proven expertise in bringing vaccines, novel vaccines from bench to licensure, and we would leverage that.

Now the capacity, I would say, we have to invest, of course, depends heavily on Lyme success, because you know that the economics from the deal with Pfizer are favorable, and you know that besides milestones, the royalties from Lyme would, of course, go straight down to the bottom line, and as such, could allow us to invest significantly in enhancing our pipeline both organically as well as strategically while even potentially being completely financially self-sustainable. We believe that this is a very appealing strategy.

It's a very appealing strategic outlook. As you know that, many, many times, it's all about Lyme, and of course, it depends on the Lyme licensure, be it Europe, US, both, or just one, and the commercial success of this vaccine then later on.

We believe overall, strategically, yes, there is a benefit. Coming to your question on Nantes, yes, we as part of our restructuring program that Peter mentioned earlier, and I mentioned it, too, we have also consolidated all of our R&D operations into Vienna.

Which means that all R&D is now centralized in Vienna, and we shut down the R&D operations we had in Nantes. This consolidation brings efficiency and cost reduction, and this is something that, of course, we don't see immediately because it comes over time.

We had significant redundancy costs and restructuring costs. This is certainly something where we see a significant benefit in the future to come.

Besides the fact that we disclosed in the half-year report that, of course, we get also some proceeds from the sale of the building that we are now executing on.

Operator

Thank you. Thank you.

We are now going to move to our next question. This question comes from Shyam Kotadia from Goldman Sachs.

Please go ahead.

Shyam Kotadia

Hi there. Thank you for taking my questions.

Two on the modeling side of things. You've mentioned your ongoing restructuring program, I just wanted to check, how should we be thinking about SG&A and R&D for the remainder of the year, especially noting SG&A came in lower than expectations?

I can see that linked to that you no longer call out the 25% to 35% reduction in OpEx versus 2025 that you did in your prior release. Does that hold?

That's the first question. Then the second question is on what is the realistic expectation for gross margin in second half '26?

I realize you're not guiding on it specifically, but could you help us understand how it could compare to last year, given that you're mentioning an uptick there? Thank you.

Peter Bühler

Hey. Thanks for the questions.

Let me first get into your questions on the restructuring and the impact on R&D and SG&A. You saw on SG&A in particular a trend that started already last year when we did some efficiency improvements, it continues this year, and we expect clearly continued efficiency in SG&A spend.

I think what you see in the first half-year is, in a way, what we will continue to see in the future. As I said, there were also some one-off costs in there that we will, of course, not have anymore.

We eliminated a number of positions, and of course, in H1, we don't see an impact of that, and you will see that going forward. I think, similarly, on R&D, we would expect to see in the second half-year the decrease in cost.

To your point, yes, we did provide guidance in the last press release about rough guidance on where we see costs going versus last year, and that still holds true. We have not confirmed it, we have also not revised it, which means it still holds true.

On gross margin, yeah, so as you understood, there was a lot of one-off events and also some non-cash effects in the first half-year. In the second half-year, we clearly expect a much better gross margin than in the first half-year.

I would say, overall for the year, we will probably not get exactly to where we were last year, but we will get certainly much closer to the full-year gross margin we recorded last year. Then I would also expect a positive trend getting into 2027.

Shyam Kotadia

Thank you.

Operator

Thank you. We are now going to take our next question.

This one comes from Simon Scholes from First Berlin. Please go ahead.

Simon Scholes

Yes, good afternoon. I've just got a question on IXCHIQ.

The local version of the IXCHIQ vaccine has now been approved in Brazil. I was wondering if you could give us some indication of how long it might be before the start of commercial sales of the vaccine in Brazil?

Thomas Lingelbach

Basically, our partner, Butantan, are currently in the midst of the launch planning. Therefore, I would consider it a bit too early to really talk about, I would say, commercial prospects.

There is a clear desire to include chikungunya vaccine into the healthcare system. There is a significant opportunity both public as well as private markets in Brazil, and you know that when we look at the demand that we have seen or we are seeing from our drug substance supplies to Butantan, and we recorded in the first half the first revenues from drug substance sales, because remember, the locally produced product means we are shipping drug substance, and they turn it into drug product and final product.

Just by the way of what we see there, we really expect this to become a very significant opportunity. It's too early, and I don't want to throw out numbers here without having a clear confirmation from our partner.

Simon Scholes

Okay. That's very helpful.

Just a supplementary on the pilot vaccination program. I think you've vaccinated 50,000 persons so far.

How long do you expect this pilot vaccination program to continue for?

Thomas Lingelbach

Yeah. It's a good question.

Remember, this is a program that is owned by the Ministry of Health, by the government. The government objective is to have at a minimum of 100,000 people vaccinated, because what we are generating there is also a so-called active pharmacovigilance, especially given that chikungunya is a live-attenuated vaccine, and we have been discussing in the past all the issues that arose from that.

It is important that before they include it in a very, very broad public vaccination schedule, they need to see active pharmacovigilance, they need to see how this all works out, and that's why their internal target has been a minimum of 100,000 doses vaccinated, which could be reached, I think, by the latter part of the year. That's all I can say to that.

Simon Scholes

Okay. Thanks very much.

That's really helpful.

Operator

Thank you. There are no further questions for today.

I will now hand the call back to Thomas Lingelbach for closing remarks.

Thomas Lingelbach

Thank you so much for your questions today. Thank you so much for following Valneva so closely, and of course, Lyme in particular right now.

As I said, we share the positivity that you could see across Pfizer's different communications. We are very happy about the progress that is currently being made, and we are optimistic that we're going to see approvals for the vaccine in the next 12 months, and as such, enabling a nice strategic prospects as I've responded to following Suzanne's questions earlier.

With that, thanks again, and have a good remainder of the day. Goodbye.
