Influenza kills around 36,000 people annually in the U.S. but they are the least effective of all our vaccines. The influenza virus is constantly changing, and there is a lot of guesswork involved in choosing which strains to use in each year’s vaccine.The benefit to the population depends on individuals getting the vaccine. They may not benefit personally, but they indirectly benefit others by reducing transmission rates in the community and increasing herd immunity.
