Vaccination Guidelines for Patients with HbSS Sickle Cell Disease
Introduction to Vaccination
- The American Academy of Pediatrics recommends that patients with HbSS sickle cell disease receive comprehensive pneumococcal, meningococcal, Haemophilus influenzae type b, and annual influenza vaccination due to functional asplenia, which places them at 20-30 times higher risk of invasive bacterial infections with mortality rates of 30-70% 1, 2, 3
Pneumococcal Vaccination
- The Centers for Disease Control and Prevention (CDC) recommends administering a complete PCV series (PCV15 or PCV20 preferred) with catch-up dosing through 71 months of age for children under 6 years 1, 4
- For children 6-18 years previously vaccinated, if at least one dose of PCV20 was received, no additional pneumococcal vaccines are needed 1, 4
- For adults (≥19 years), the CDC recommends administering PCV13 first, followed by PPSV23 at least 8 weeks later, with a second dose of PPSV23 five years after the first dose 2, 3
Meningococcal Vaccination
- The CDC recommends administering MenACWY vaccine at a young age (starting at 2 months) with a booster every 5 years for lifelong protection 1, 4, 2, 3
- The CDC also recommends giving MenB vaccine after age 10 years per recommendations for functional asplenia 1, 4, 5, 3
Haemophilus Influenzae Type B Vaccination
- The CDC recommends verifying completion of primary Hib series by 6 months with a booster at 6-8 months later, or a single dose if vaccinated after 14 months of age 5, 6, 2
Annual Influenza Vaccination
- The CDC recommends administering inactivated influenza vaccine (IIV) annually starting at 6 months of age 2, 3
- The CDC advises against using live attenuated influenza vaccine (LAIV/nasal spray) in patients with functional asplenia 2, 3
Additional Standard Vaccinations
- The CDC recommends following the standard age-appropriate schedule for hepatitis B vaccination, with no special dosing required for HbSS patients without renal disease 7, 8
- The CDC recommends administering HPV vaccine series to patients aged 11-26 years per standard recommendations 7, 8
- The CDC recommends giving DTaP for children under 7 years and Tdap for adolescents and adults per the standard CDC schedule 7, 2
- The CDC recommends administering MMR and Varicella vaccines per the standard schedule if not immunosuppressed, as these live vaccines are generally safe in HbSS patients 7, 8
Patient and Family Education
- The American Academy of Pediatrics recommends educating patients and families about lifelong infection risk and the need for immediate medical attention for fever >101°F (38°C) 3
- The American Academy of Pediatrics also recommends reinforcing daily home spleen palpation and recognition of splenic sequestration crisis 1, 4
- The American Academy of Pediatrics advises emphasizing the continuation of penicillin prophylaxis even after vaccination completion, particularly in patients with a history of invasive pneumococcal infection or surgical splenectomy 1, 4
