White House warns the US can't buy updated Covid-19 vaccines 'for every American who wants one' without more funding

White House Covid-19 coordinator Dr. Ashish Jha warned Wednesday that without more funding from Congress the US will not be able to buy enough Covid-19 vaccines for every American who wants an updated shot later this year. Scientists are working to develop new vaccines that would offer additional protection from infection and severe illness from new variants, including the possibility of a bivalent vaccine, a vaccine that would combine a currently approved vaccine with an Omicron-specific vaccine, for example. The US Food and Drug Administration could make a decision as soon as next month based on data from manufacturers Moderna and Pfizer for distribution in the fall.
