Splenectomy Vaccination Recommendations

Core Vaccination Requirements

The Centers for Disease Control and Prevention recommends that all patients undergoing splenectomy require three essential vaccines: pneumococcal, meningococcal, and Haemophilus influenzae type b, administered at least 2 weeks before elective surgery or at least 2 weeks after emergency splenectomy 1, 2

The American Academy of Pediatrics recommends administering PCV13 (or newer PCV15/PCV20) first, followed by PPSV23 at least 8 weeks later for vaccine-naïve patients aged ≥2 years 1, 2, 4
The Centers for Disease Control and Prevention recommends that PPSV23 should be given ≥8 weeks after PCV13 for optimal protection 1, 2
A second dose of PPSV23 should be administered 5 years after the first dose 1, 2
Reimmunization with PPSV23 is recommended every 5-10 years for lifelong protection 5, 4

The Centers for Disease Control and Prevention recommends that asplenic patients require both MenACWY and MenB vaccines due to 40-70% mortality rates from meningococcal infections 3, 6
For patients aged ≥10 years, MenACWY vaccine should be administered in 2 doses given ≥8 weeks apart 3
Revaccination with MenACWY is recommended every 5 years for lifelong protection 1, 2, 3

The American Academy of Pediatrics recommends that one dose of Hib vaccine is required for all unvaccinated asplenic persons aged ≥5 years 1, 2, 4

The Centers for Disease Control and Prevention recommends annual inactivated influenza vaccine (IIV) for all asplenic patients aged ≥6 months 6
Live attenuated influenza vaccine (LAIV/nasal spray) should never be used in asplenic patients 1, 6

The Infectious Diseases Society of America recommends lifelong prophylactic antibiotics for all asplenic patients, with highest priority in the first 2 years post-splenectomy 5, 4, 6
Patient education is crucial, and patients should be educated about lifelong infection risk and the importance of seeking immediate medical attention for fever >101°F (38°C) 5, 4, 6

The lifelong risk of overwhelming post-splenectomy infection is clinically significant with mortality rates of 30-70%, making proper vaccination critical 5, 4, 6
