Medicare Part D covers most vaccines and immunizations. However, there are certain vaccinations that are always covered by Part B:
- Influenza (flu) shots, including both the seasonal flu vaccine and the H1NI (swine flu) vaccine
- Pneumococcal (pneumonia) shots
- Hepatitis B shots
- COVID-19 vaccine
Part B also covers vaccines after you have been exposed to a dangerous virus or disease. For example, Part B will cover a tetanus shot if you step on a rusty nail, or a rabies shot if you are bitten by a dog.
