Valneva is advancing toward U.S. FDA accelerated approval of the France-based biologics company’s VLA1553 after the specialty vaccine was shown to be safe and effective against mosquito-transmitted chikungunya disease, in a published analysis of Phase III results.

Moderna Inc. plans to develop and begin testing vaccines targeting 15 of the world’s most worrisome pathogens by 2025 and will permanently waive the company’s COVID-19 vaccine patents for shots intended for certain low-income and middle-income countries.

French specialty vaccine maker Valneva shared positive topline results from ongoing trials for a potential single-shot vaccine against chikungunya.

After months of bad news regarding Covid-19 vaccine manufacturing issues, Emergent BioSolutions posted positive two-year data related to the company’s investigational chikungunya virus virus-like particle (CHIKV VLP) vaccine candidate.
