When should I get vaccinated?

You should get your flu shot annually, as soon as the flu vaccine is available in the late summer or early fall1. If you don't have a chance to get a flu shot right away, vaccination throughout the influenza season into the winter months and beyond is still recommended and beneficial when influenza virus is still around1.

Who should not get a flu shot?

  • Anyone who has ever had a severe allergic reaction to eggs, egg products, or any components of the vaccine2.

  • Anyone who has ever had Guillain-Barré syndrome (GBS) within 6 weeks after a previous influenza vaccination2.

Your healthcare provider can help you decide whether you should get a flu shot and which one might be right for you.

When is it too late to get a flu shot?

Flu vaccines are usually available in the late summer or early fall. Depending on the year, the peak may occur as early as late fall or as late as early spring1, so December or January wouldn’t be too late to get a flu shot. Even so, you are encouraged to get a flu shot as soon as the vaccine is available1.

Why do I need a flu vaccine every year?

The seasonal flu can pose a public health threat. There are two types of influenza viruses that commonly infect humans and have the potential to cause epidemics: A and B3. By getting a flu shot, you can help protect yourself from the influenza strains contained in the flu vaccine2.

This is why the National Advisory Committee on Immunization (NACI) recommends annual influenza vaccination for individuals 6 months of age and older1.

What are my vaccination options?

There are vaccine options available for people over 6 months of age, so it is important to talk to your healthcare provider about the option that might be best for you1.

Is it OK to get a flu shot at a retail store or clinic instead of at my physician's office?

Yes. Influenza vaccines are now widely available at retail stores, pharmacies, workplace flu clinics, and many more places4. You should get vaccinated at the place that is most convenient for you.

Can I get influenza from the flu shot?

No. The ingredients of the inactivated flu shot do not contain the live virus, so it is impossible to get influenza from an inactivated flu shot1.

There’s a FLUZONE® vaccine for you.
