My 36-year-old patient was diagnosed with idiopathic thrombocytopenic purpura and had a splenectomy three weeks ago. Prior to the splenectomy, he had one dose each of Hib, MenB, PCV20, and MenACWY (Menveo). What vaccines are recommended now?
Since the patient is asplenic, the second dose of the primary series of MenACWY should be given at least 8 weeks after the first dose. He will need a dose of MenACWY every 5 years for the rest of his life. The 3-dose series of MenB (whether Trumenba [Pfizer] or Bexsero [GSK]) should be completed. The first booster dose of MenB will be due one year after completion of the primary series and subsequent booster doses are recommended every 2–3 years for the rest of his life. The same MenB vaccine should be used for all doses in the series, including booster doses. People who receive Trumenba brand MenB vaccine have an option to receive MenABCWY (Penbraya, Pfizer) when both MenACWY and MenB vaccines are due at the same visit, as long as doses of Penbraya are spread out by at least 6 months. The patient has already received one dose of PCV20, in accordance with pneumococcal vaccination recommendations for immunocompromised adults younger than age 50, so no further doses are needed. Based on the patient’s age, only one dose of Hib vaccine is recommended, so no further doses are needed. The patient should receive influenza vaccine annually.
Any of these vaccines can be given at the same appointment.
