Medicare Vaccines and Infection Prevention: Coverage and Cost Sharing
Adapted from Your Medicare Benefits, Centers for Medicare & Medicaid Services. The selected guidance concerns Medicare coverage and payment, not a recommendation for medical treatment. Numbered page references below refer to the linked source publication.
Coverage can depend on medical necessity, the setting, provider participation, and your plan’s rules. Use the cited publication for the full conditions and check the plan year when comparing costs or enrollment choices.

Vaccines
Vaccines work with your body’s natural defenses to safely develop immunity (protection) against harmful germs (like viruses and bacteria). You usually get vaccines as a shot injected into your arm by a doctor or other health care provider. Part B covers preventive vaccines for:
- COVID-19: Go to pages 30–31.
- Flu: Go to page 47.
- Hepatitis B: Go to page 51.
- Pneumococcal: Go to page 88.
Part B also covers some non-preventive vaccines (like tetanus) when they’re related directly to treating an injury or illness.
Medicare drug coverage (Part D) covers all adult vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) that aren’t covered under Part B, including vaccines for:
- Respiratory Syncytial Virus (RSV): Go to pages 100–101.
- Shingles: Go to page 103.
- Tdap: Go to page 107.
- Traveling (like yellow fever and chikungunya), measles, and more.
Your Part D plan won’t charge you a copayment or apply a deductible for vaccines ACIP recommends. Contact your Part D plan for details, and talk to your provider about which vaccines are right for you.
Pre-exposure prophylaxis (PrEP) for HIV prevention
PrEP uses antiretroviral medication to lower your risk of getting HIV (human immunodeficiency virus). If you don’t have HIV, but your doctor or other health care provider determines you’re at an increased risk for HIV, Part B covers PrEP medication and related services.
If you qualify, covered services include:
- FDA-approved oral or injectable PrEP medication. If you’re getting an injectable drug, Part B also covers the fee for injecting the drug.
- Up to 8 individual counseling sessions (including HIV risk assessment, HIV risk reduction, and medication adherence) every 12 months.
- Up to 8 HIV screenings every 12 months.
- A one-time hepatitis B virus (HBV) screening (you may be able to get more screenings if you’re at high risk for HBV or you’re pregnant).
Costs If you get PrEP medications from a pharmacy that’s enrolled in Part B, you’ll pay nothing out of pocket for your medications. Ask your health care provider to include a diagnosis code on your prescription to help the pharmacy. If you’re in a Medicare Advantage Plan, you’ll usually pay nothing out of pocket for PrEP at any pharmacy in your plan’s network. Contact your plan for more specific cost information.
If your provider accepts assignment, you’ll also pay nothing out of pocket for injectable PrEP drugs, HIV and HBV screenings, and counseling sessions (because they’re preventive services).
Note: Contact your pharmacy to make sure they can bill Medicare Part B. If you don’t, you might have to pay the full cost of PrEP yourself. Most pharmacies (including national chains) can bill Part B, but some smaller pharmacies can’t. If your regular pharmacy can’t bill Part B, we can help you find a pharmacy where you can get your PrEP. Call 1-800-MEDICARE (1-800-633-4227). TTY users can call 1-877-486-2048.
