Fall Virus Vaccines

There seems to be a perception that the shots based on the 20 20 virus are outdated. But trevor bedford, an evolutionary iologist at the fred hutchinson cancer center, thinks it's a good bet the fall virus will be pretty similar. Since those versions have been wildly successful at spreading, he expect that trend to continue. And this summer, vaccine makers and the fda will be testing those new boosters to make sure they are just as successful at keeping up.
