Beyond HPV, Recbio is developing ReCOV, a recombinant COVID-19 vaccine candidate which has progressed to Phase II/III trials and received Emergency Use Authorization in Mongolia. Further expanding its portfolio, the company is advancing REC610, a novel adjuvanted recombinant shingles vaccine, with its clinical trial application accepted in China and positive Phase I data from overseas. Other preclinical stage candidates include an mRNA COVID-19 vaccine, a recombinant adult tuberculosis vaccine, a virus-vectored adult tuberculosis vaccine, a recombinant influenza quadrivalent vaccine, a recombinant hand-foot-mouth disease quadrivalent vaccine, and a novel adjuvanted recombinant respiratory syncytial virus vaccine (REC625). Founded in 2011, Recbio leverages core technology platforms, including novel adjuvants, protein engineering, and immunological evaluation, to create its diverse vaccine candidates. The company has expanded its global reach through strategic partnerships, including a July 2025 licensing and technology transfer agreement with Biological E.
