What you need to know about the flu shot

Who should get a flu shot?

According to the Centers for Disease Control, almost everyone age 6 months and up, especially children younger than 5, adults 65 and older, pregnant women and anyone with a weakened immune system or chronic condition (like asthma).

Even healthy people should get the shot

“Healthy” people can still get sick or carry the flu virus and spread it to others without showing symptoms. No matter how healthy you feel, the shot helps to kick-start your immune system and prepares your body to fight off the flu.

Don’t skip a year

It's important to get a flu shot every year. Flu virus strains change and vaccine protection declines over time, so last year’s vaccine may not protect you from getting sick.

The shot can’t give you the flu

However, sometimes people are exposed prior to getting the shot and get sick before it takes effect (which is about 2 weeks). That’s why it’s important to get the shot early.

Egg-free flu shots are available

If you’re allergic to eggs, ask your healthcare provider or pharmacist if the egg-free alternative is right for you.

What if the flu shot doesn’t always work?

The flu shot protects against many of the common seasonal strains. Even if different types of the virus spread, getting a shot can lessen the severity of the illness.

Think you already have the flu?

See your healthcare provider or visit an urgent care clinic right away. They may prescribe an antiviral drug to help reduce the severity and duration of the flu.
