Use this map to look up where you can get your flu shot

You know you need to get a flu shot, but you're not sure where to go.

The HealthMap Vaccine Finder has got you covered. Simply go to their website and type in an address.

The map is hosted through a partnership with the federal government, Harvard University, and Boston Children's Hospital.

Most of the locations that pop up offer free flu shots for insured patients, since almost all insurance plans, including Medicare Part B, cover immunizations.

Over 90 percent of people who get their flu shots at Walgreens don't have to pay anything because their insurance picked it up, the company reported in a press release.

Some insurers will require a copay. For people paying out pocket, prices will vary. A flu shot at a CVS Minute Clinic is $31.99.

You can find other vaccines in your area on the site, too, but if you just want to search for the flu shot, be sure to only check that box.

The site also lists what form of flu shot is available at each location. "High-Dose" means the regular kind you get as a shot, whereas "Intradermal" uses a smaller needle to inject the vaccine into your skin instead of your muscle.

"Cell Based" flu shots were grown using cells instead of the traditional method of growing the vaccine in chicken eggs - an option for people who are allergic to eggs or who object to getting a vaccine that uses them.

"Quadrivalent" vs. "Trivalent" refers to the number of strains of the virus that the shot protects against (four vs. three).

If you're not sure what kind you want to get, just ask the doctor, nurse, or pharmacist when you get there, or talk to your primary care provider before you go.
