How often should personnel receive the influenza vaccine?

The correct response is based on public health guidelines and recommendations for influenza vaccination. The influenza vaccine is designed to target the specific strains of flu virus that are expected to circulate during the flu season. Because these strains can change from year to year, vaccination is recommended on an annual basis.

Receiving the flu vaccine every year helps to ensure that individuals maintain optimal immunity levels against the most current and prevalent strains of the virus. This annual recommendation is especially critical for certain high-risk groups, including children, the elderly, and those with underlying health conditions, to reduce the risk of severe illness and promote community immunity.
