Even healthy people need a flu vaccine.
Influenza (flu) is a contagious disease which affects the lungs and can lead to serious illness, including pneumonia. Even healthy people can get sick enough to miss work or school for a significant amount of time or even be hospitalized. The flu vaccine is recommended for everyone 6 months of age and older.
Pregnant women, young children, older people, and people with certain chronic medical conditions like asthma, diabetes and heart disease are at increased risk of serious flu-related complications, so getting a yearly flu vaccine is especially important for them.
Is the flu vaccine safe?
Yes. The flu vaccine is safe. They have been given to hundreds of millions of people for more than 50 years and have a very good safety track record. Each year, CDC works closely with the U.S. Food and Drug Administration (FDA), and other partners to ensure the highest safety standards for flu vaccines
Can’t I wait and get vaccinated when/if flu hits my community?
It is best to get vaccinated before flu begins to spread. It takes about two weeks for the flu vaccine to provide full protection, so the sooner you get vaccinated, the more likely it is that you will be fully protected once flu begins to circulate in your community.
You need to get a flu vaccine every year.
You need to get a flu vaccine every year to protect yourself against the viruses that research suggests are most likely to circulate each season. There are two reasons for getting a flu vaccine every year:
1. The first reason is that because flu viruses are constantly changing, flu vaccines
may be updated from one season to the next to protect against the viruses
research indicates may be most common during the upcoming flu season.
2. The second reason that annual vaccination is recommended is that a person’s
immune protection from the vaccine declines over time. Annual vaccination is
needed for optimal protection.
