Myths and Misconceptions • I didn’t get the flu shot last year and didn’t get sick. I don’t need a flu shot. • I’m young and healthy, the flu is just a bad cold. I don’t need a flu shot. • Getting the flu shot will give me the flu • Flu shots are not worth getting because they are not very effective
