Do any of the bacterial vaccines that are recommended for people with functional or anatomic asplenia need to be given before splenectomy? Do the doses count if they are given during the 2 weeks prior to surgery?

Pneumococcal conjugate vaccines, Haemophilus influenzae type b vaccine, meningococcal ACWY conjugate vaccine, and meningococcal B vaccine should be given at least 14 days before splenectomy, if possible. Doses given during the 2 weeks (14 days) before surgery can be counted as valid. If the doses cannot be given prior to the splenectomy, they should be given as soon as the patient’s condition has stabilized after surgery. Pneumococcal polysaccharide vaccine should be administered 8 weeks after the dose of PCV13 for people 2-18 years of age or after PCV15 for people 19 years or older. People age 19 or older who receive PCV20 do not need PPSV23.
