Cancer Survivor Reboots Immune System With New Vaccines
23 May
Summary
- Amelia Sullivan relapsed with cancer, leading to a stem cell transplant.
- Her immune system was rebuilt after treatment destroyed healthy stem cells.
- She received multiple vaccines in April 2026, a year after remission.
Amelia Sullivan's battle with cancer took a turn at age 20 with a stage 2 Hodgkin lymphoma diagnosis. After initial chemotherapy led to remission in March 2024, she relapsed, undergoing a stem cell transplant on March 10, 2025. This treatment, while crucial, destroyed her healthy stem cells and immune system.
Rebuilding her immune system meant erasing immunological memory, leaving her vulnerable. Sullivan experienced engraftment syndrome post-transplant, requiring ICU care and life support. Her recovery involved strict precautions against foodborne illnesses and avoiding crowds.
Despite challenges, including contracting multiple flu strains, Sullivan views her health journey with resilience. As of May 23, 2026, marking one year in remission, she has begun a new vaccination regimen. In April 2026, she received seven shots, with more planned, signifying a vital step in reclaiming her health and future.
