Getting vaccinated is generally encouraged for people with breast cancer — staying up to date is one of the best ways to protect yourself from severe illness. That said, timing really matters when you're in treatment.

Here are some key things to keep in mind:

- Coordinate with your care team — Your oncologist may recommend scheduling vaccines between treatment cycles, when your immune system is more stable
- Avoid live vaccines — This is important during cancer treatment, but the good news is that neither the flu shot (the injected version) nor the COVID-19 vaccines are live vaccines
- Check your last COVID-19 dose — The updated booster should be given at least two months after your most recent COVID-19 shot For the 2025-2026 season, Pfizer's updated COVID-19 vaccine (Comirnaty) is approved for:

- People ages 5–64 with at least one condition that raises the risk of severe COVID-19
- All adults 65 and older

Breast cancer qualifies as a high-risk condition, so you'd likely be eligible. Bringing this up at your next appointment is a great starting point — your care team can help you plan the best timing for both vaccines together.
