Influenza, or “the flu,” can be a serious illness for older adults. However, getting your annual flu shot can help reduce your risk of getting the flu and spreading it to others. And if you have Original Medicare, it’s free!1
Let’s explore details about the flu shot, the parts of Medicare that cover it and more.
The influenza vaccine, or “flu shot,” is a vaccine that helps protect against influenza viruses. New vaccines are created every year based on research to predict the most common flu viruses for the upcoming flu season (typically fall and winter). Most flu shots are given with a needle, commonly in the arm.2
There are 2 parts of Medicare that cover the flu shot:
Part B, which is part of Original Medicare, covers 1 seasonal flu shot once per flu season. Part C plans must provide all of the benefits of Original Medicare, so they also cover 100% of 1 seasonal flu shot. Some Part C plans may even cover a coinsurance or copayment for the flu shot if you get it from a doctor who accepts Medicare and the terms of your Medicare Advantage plan.
Here’s a look at all 4 parts of Medicare and their flu shot coverage:
Medicare plan type | Flu shot coverage |
|---|---|
Not covered under Part A | |
Covered 100% under Part B | |
Covered 100% under Part C | |
Not covered under Part D |
Medicare Advantage plans help expand your Medicare coverage beyond Original Medicare, often with extra benefits. Explore Humana’s Medicare Advantage plans in your area today!

A regular flu shot contains a traditional dose of flu virus antigens. These are typically given to healthy people under 65 years of age.
High-dose flu vaccines, sometimes called “senior flu shots,” are typically given to people age 65 and older and include 3–4 times more antigens than traditional flu vaccines. Examples of high-dose vaccines include Fluzone High-Dose Quadrivalent, Flublock Quadrivalent and Fluad Quadrivalent. Studies have shown that high-dose flu vaccines can trigger a better immune response in older adults than the traditional flu vaccine.3
If you have Medicare Part B or Part C, you pay nothing for a flu shot.
If you don’t have Medicare or health insurance, the flu vaccine could cost $20–$120 out of pocket. The price can depend on the type of flu shot you get and where you get it.4
Note: High-dose (senior) flu shots can be more expensive than traditional flu shots.
According to the Centers for Disease Control and Prevention (CDC), flu vaccination can help:5
The CDC recommends that everyone 6 months and older get a flu shot every flu season (with rare exceptions). The CDC’s Advisory Committee on Immunization Practices has made this universal recommendation since the 2010–2011 flu season.2
If you only need 1 shot for the flu season, the CDC recommends getting it early September or October. It can take up to 2 weeks for your body to produce enough antibodies to fight the flu after getting the vaccine.6
Note: Flu activity usually peaks between December and February but can last as late as May.
Getting an annual flu shot is an important way to stay active, healthy and independent. To locate a nearby vaccine location, see how to

The flu vaccine can work for up to 6 months but is typically most effective in the first 3 months.7
Maybe. It depends on if the pharmacy accepts Medicare payments. Before you get a flu shot at a pharmacy for the first time, call ahead to make sure they accept Medicare assignments.
