How long do flu shots last?

The flu vaccine can prevent severe consequences and death, but how long does it last? Who should get it?

Influenza usually begins in early fall and peaks between December and February, so it’s recommended that you get the flu vaccine by November to prevent severe illness and death. According to Judith James, M.D., vice president of clinical operations at the Oklahoma Medical Research Foundation, on average, a flu shot will provide him with protection for six to eight months, but the individual’s immune system will be more susceptible to the vaccine. Persistence may be affected.

Influenza viruses mutate rapidly, so flu vaccines should be different each year. Therefore, experts recommend getting a new flu vaccine every year.

For children aged 6 months to 8 years who receive their first flu shot, the CDC recommends two doses at least 4 weeks apart. Children in this age group are more likely to benefit from a booster, as their bodies need to develop a protective response against the flu virus: her two doses of the vaccine reduce her risk of contracting the flu by about 50. % was also shown to decrease.

For adults, two doses of the influenza vaccine have not been shown to provide more benefit than one dose, so it is recommended that adults receive only one dose each flu season.
