The flu vaccine is important to get. * Every year the vaccine is updated to match the new mutation which is why you need to get one every year. * Some years the vaccine is not fully protective, but it will still reduce the severity and duration. This could mean the difference between life and death for at-risk populations: old, young, immune-comprised. * If enough people get it, it provides herd immunity for people who can't take it such as babies less than 6 months. I know someone with a child who has an immune condition who can't get the flu vaccine. The father didn't think he needed to get it because he didn't think the flu was that big of a deal, and it's not for most healthy people. Well he gets the flu, gives it to his son, and the son ends up in the ICU. Thankfully the son survived. The father now always gets the flu shot.
