Mar 20, 2020 at 1:53 comment added cbeleites Also, when we say there's a new flu vaccine every year that is often not entirely new. If you look at the wikipedia list of strain recommendations en.wikipedia.org/wiki/…, you'll see that quite often one strain stays for several years - but there are 3 - 4 of them in the composition for each year, and the new may differ in only one of them.
