People under the age of 45 were the least likely to report being vaccinated.

The top three reasons why they didn’t want the shot were: bad side effects; thinking they’ll get the flu from the shot; or thinking it doesn’t work.

Some think the side effects are worse than the flu itself, but that’s just a myth. Usually the only side effect is a sore arm.

It’s also a myth that getting the vaccine gives you the flu. The flu vaccine is inactive and cannot cause the infection. If you do get sick after getting the vaccine, it’s just a coincidence.
