Meningococcal Vaccination After Splenectomy

Rationale for Timing of Meningococcal Vaccination

The American College of Surgeons recommends meningococcal vaccination at least 2 weeks before elective splenectomy to allow for optimal antibody response and protection before the patient becomes functionally asplenic 2, 3
Antibody formation generally takes 9 days, making the 2-week pre-surgery window sufficient for developing protective immunity 1
For patients undergoing elective splenectomy, meningococcal vaccines should be administered at least 2 weeks before surgery whenever possible, as recommended by the Centers for Disease Control and Prevention 4
If the meningococcal vaccine was administered 2 weeks before splenectomy, it does not need to be repeated post-operatively, according to the American College of Cardiology 1, 2

Asplenic patients are at high risk for infections with Neisseria meningitidis, with mortality rates ranging from 40% to 70%, as reported by the American College of Physicians 1
The Infectious Diseases Society of America recommends the tetravalent conjugated meningococcal vaccine (MenACWY) for asplenic patients with a strength of recommendation AII 1, 5
For asplenic patients aged ≥10 years, the recommended primary vaccination is 2 doses of MenACWY given ≥8 weeks apart, according to the Advisory Committee on Immunization Practices 3
Vaccination against serogroup B meningococcus (MenB) is also recommended for asplenic patients, as suggested by the American Academy of Pediatrics 5, 3

The Centers for Disease Control and Prevention recommend revaccination with MenACWY every 5 years in asplenic patients 1, 3
For MenB, a booster dose is recommended at 1 year after completion of primary vaccination and every 2-3 years thereafter, as recommended by the Advisory Committee on Immunization Practices 3

If preoperative vaccination was not possible and the patient did not receive meningococcal vaccination 2 weeks prior to splenectomy, vaccination should be performed 14 days after surgery (AI), as recommended by the American College of Surgeons 1
All recommended vaccines for asplenic patients (pneumococcal, Haemophilus influenzae type b, and meningococcal) can be given simultaneously if administered at different injection sites, according to the Infectious Diseases Society of America 1

Overlooking the need for revaccination: Asplenic patients require meningococcal revaccination every 5 years due to lifelong risk of infection, as reported by the American College of Physicians 1, 3
Neglecting other essential vaccines: Asplenic patients also require pneumococcal and Haemophilus influenzae type b vaccines for comprehensive protection, as recommended by the Advisory Committee on Immunization Practices 2
Inadequate patient education: Patients should be educated about their increased infection risk and the need to seek immediate medical attention for fevers over 101°F (38°C), as suggested by the American Academy of Family Physicians 2
