HHS says the elimination of 22 mRNA vaccine development projects for COVID-19 and bird flu signals a shift in vaccine priorities.

The US Department of Health and Human Services (HHS) plans to cancel $500m (£376m) in funding for mRNA vaccines being developed to counter viruses like the flu and Covid-19. The move will impact 22 projects being led by major pharmaceutical companies, including Pfizer and Moderna, for vaccines against bird flu and other viruses, HHS said.
