There only about 4 mutations of the flu. And we can not get rid of it with yearly flu vacine shots.
Yes, there are only four strains of flu virus, but there are multiple mutations to each of them, even within a single flu season, that can limit a vaccine’s effectiveness. Unlike the coronavirus that causes COVID-19, which has a stable spike structure that scientists have targeted with the new vaccines, flu viruses can mutate in ways that yield vaccines ineffective or marginally effective. Add to that the fact that only about 45% of the adult US population gets vaccinated each year, and it’s pretty easy to see why there are still outbreaks each year. The good news is that there are new types of universal flu vaccines in development that are expected to be effective against all types of flu and perhaps will only require a single lifetime vaccination.
