Vaccination after hematopoietic stem cell transplantation

From IDWiki
  • Following hematopoietic stem cell transplantation, the immune system is considered to have been never immunized
    • Recipients need essentially all (allogeneic) or most (autologous) routine immunizations following transplantation
    • Recipients recipients respond poorly to polysaccharide vaccines
    • Titres can be checked to confirm immune response and direct further revaccination
  • Most inactivated vaccines are started around 6 months after vaccination
  • Most live vaccines can be given after 24 months, including univalent varicella, MMR, and yellow fever faccines
  • Close contacts should also ensure vaccinations are up to date

Inactivated Vaccines

  • Recommended post-transplant
    • 3-9 months: conjugate pneumococcal vaccine, 3 doses 1 month apart
    • 4-6 months: annual inactivated influenza vaccine
    • 6 months: quadrivalent meningococcal vaccine, 1 dose (or a second dose after 8 weeks if first is given before 6 months)
    • 6 to 12 months:
      • Polysaccharide pneumococcal vaccine: 1 dose at least 6 to 12 months after conjugate vaccine, with a booster 12 months later
        • Delay if ongoing GVHD, and given a fourth dose of Pneu-C-13 instead
      • Diphtheria: 3 doses 1 month apart, with booster at 18 months
      • Pertussis: 1 dose (if given alone), with booster at 18 months
      • Inactivated polio: 3 doses 1 month apart, with booster at 18 months
      • Tetanus: 3 doses 1 month apart, with booster at 18 months
      • Hepatitis B: 3 doses (at 0, 1, and 6 months) followed by HBsAb titres and a booster if titre less than 10 IU/L
      • Haemophilus influenzae: 3 doses at least 4 weeks apart
    • Inactivated herpes zoster vaccine is not routinely indicated, but can be considered in those age 50 years and older
  • Not routinely given, but no contraindications: hepatitis A, inactivated oral cholera, Japanese encephalititis, rabies, inactivated intramuscular typhoid, tick-borne encephalitis, and HPV

Live Vaccines

  • Contraindicated vaccines include: BCG, live influenza vaccine, rotavirus, smallpox, oral typhoid, oral polio, live herpes zoster (Zostavax)
  • Other live vaccines, including univalent varicella, yellow fever, and MMR, can be given starting at 24 months provided they are considered immunocompetent
  • In other to receive live vaccines:
    • At least 24 months post-transplant
    • No ongoing graft-versus-host disease
    • No corticosteroids or other immunosuppressants for at least 3 months
    • No immunoglobulin in the past 8 to 11 months (except for yellow fever vaccine)
    • Assessed by primary team and considered immunocompetent
  • Following immunization, check titres for varicella and MMR
