Protecting against the flu

Scientists make different flu vaccines every year for preventing the flu because the strains of flu virus change every year. So you do need to get vaccinated annually.

"By far, the single best way to prevent the flu is for individuals, especially people at high risk for serious complications from the flu, to get a vaccination" — Centers for Disease Control and Prevention (CDC)
