Flu shots are now available. Most members can get one at no extra cost. You can get an updated COVID-19 vaccine at the same time. It’s safe and convenient. Check if your location offers both shots.

The Centers for Disease Control and Prevention (CDC) recommends getting your flu shot by the end of October.

Additionally, doctors recommend that children get a flu vaccine every year, starting at 6 months old. They should get a second flu vaccine before 2 years of age.

The updated COVID-19 vaccines are expected to be available this Fall. Please ask your doctor if these vaccines are necessary for your good health.

Hundreds of millions of Americans have safely received flu shots over the past 50 years, according to the CDC.

Severe allergic reactions from a flu shot are very rare. They’re estimated at less than one in a million doses. If a reaction happens, it is usually within a few minutes to a few hours after the shot.


Flu season peaks between December and February. But activity can last as late as May.
