Revaccination
Around 6 months after transplant, the immune system may be strong enough to begin receiving vaccines again. This process helps rebuild protection against common infections, especially those you were vaccinated for before transplant. However, timing depends on your recovery - patients with GVHD or those on extended immunosuppression may need to wait longer.
Why it matters
- Transplant wipes out previous immunity - your body needs to relearn how to fight infections
- Vaccines help protect against serious illnesses like pneumonia, flu, measles, and COVID-19
- A timely schedule reduces risk as you re-enter school, work, or public spaces
💡Tips
Ask your care team for a personalized vaccine timeline
Keep a vaccine tracker to stay organized
Let schools or workplaces know about your immune status
Be patient - some vaccines may be delayed based on your immune recovery
