- After autologous or allogeneic hematopoietic stem cell transplantation, patients need essentially all vaccines repeated
Guidelines
- DTaP-HiB-IPV: 6 to 12 months after transplant
- Diphtheria: 3 doses one month apart
- Tetanus: 3 doses one month apart
- Pertussis: 1 dose
- Haemophilus influenzae type b: 3 doses 4 weeks apart
- Polio (inactivate): 3 doses one month apart
- Hepatitis B: 6 to 12 months after transplant
- Doses at 0, 1, and 6 months using high dose (40 μg)
- Monitor HBsAb titres annually
- Influenza: annually
- Pneumococcal C-13 (Prevnar): 3 to 6 months after transplant
- 3 doses 4 weeks apart
- Pneumococcal P-23 (Pneumovax): 6 to 12 months after last dose of C-13
- 1 dose with a booster after 12 months
- If GVHD, give an extra dose of C-13 and delay P-23 until GVHD resolved
- Meningococcal conjugate (quadrivalent): 6 months
- 1 dose
- If given before 6 months, will need another after 6 months and at least 2 months after the first
- Live vaccines (varicella, MMR, and yellow fever) at least 24 months after transplant, as long as no chronic GVHD, immunosuppression has been stopped for at least 3 months, and no active underlying disease
- Contraindicated:
- Live herpes zoster vaccine
- BCG
- MMRV
- Rotavirus
- Smallpox
- Live typhoid
- Live influenza (not recommended)
