Spleen Disease — After Splenectomy
Vaccines and infection risk
Life without a spleen raises risk from encapsulated bacteria. Pneumococcal, MenACWY, MenB, and Hib vaccination — plus patient education on fever and sepsis warning signs — should be planned from prior vaccine history, age, and current national/international guidance rather than a frozen website dose list.
Outcomes of any surgical or interventional procedure may vary from person to person. Please seek a detailed consultation with your physician before any procedure.

Figure summary
This educational figure shows: After splenectomy.
Key points
Core vaccines
For adults with anatomic or functional asplenia, plan pneumococcal, MenACWY, MenB, and Hib when indicated from prior vaccine history, age, and current CDC or national guidance — not a fixed website schedule. Add annual influenza and current COVID-19 vaccines. Hepatitis B if not immune. When surgery is elective, vaccines are ideally started before operation when timing allows.
- Pneumococcal — highest priority; product/sequence per current guidance
- MenACWY and MenB — both recommended for asplenia
- Hib if not previously complete
- Annual influenza
Personalize the plan — do not freeze doses online
PCV15/20/21 and PPSV23 algorithms change over time. Prefer a dated plan from your infection-disease team against current official sources (for example the CDC adult immunization schedule: https://www.cdc.gov/vaccines/hcp/imz-schedules/adults.html) rather than memorizing static dose lists on a website. If surgery was urgent, complete vaccines once stable. Vaccines do not replace prophylactic antibiotics when prescribed; fever still needs urgent assessment.
Prophylactic antibiotics
Selected patients (especially children and early postoperative period) may receive penicillin-class prophylaxis. Duration and regimen are individualized.
Life and travel
Carry a splenectomy alert card, tell dentists and clinicians you have no spleen, and keep vaccination dates updated.
- Key note inside
Infection warning signs
High fever, rigors, confusion, or rapid deterioration after splenectomy needs urgent assessment — carry an alert card or bracelet when advised.
Travel and prophylaxis
Malaria prophylaxis and updated vaccines before travel; discuss animal bites and elective procedures with your team.
Frequently asked questions
Can I live normally without a spleen?
Yes, with vaccination, education, and prompt care for febrile illness.
When should vaccines be given before elective splenectomy?
Ideally at least 14 days before surgery when the operation can be planned; if not, the same schedule is completed once you are stable after surgery.
