According to the CDC, the single best way to protect against the flu is to get vaccinated each year.
Who should get a flu shot?
All persons aged 6 months and older are recommended for annual vaccination, with rare exception. It is especially important for those at high risk of flu complications, such as:
- Pregnant women
- Adults over age 50
- Anyone with chronic medical conditions
- People who live or work in nursing homes and other long-term care facilities
- People who live with or care for anyone in a high-risk group
- Healthcare workers
- People who live or work with children under 6 months of age
How does the vaccine work?
Each year, a flu vaccine is developed based on recently circulating strains of the flu virus. When the vaccine is given, antibodies that provide protection against the flu develop in the body.
When should I get a flu shot?
October and November are the most effective months for vaccination. You can get vaccinated as early as September, and vaccines are generally available and of value until January or beyond.
