I have a patient with paroxysmal nocturnal hemoglobinuria who is being treated with Soliris (eculizumab). Should he receive meningococcal vaccine?

Eculizumab (Soliris) and the related long-acting compound, ravulizumab (Ultomiris) bind to C5 and inhibit the terminal complement pathway. People with persistent complement component deficiency due to an immune system disorder or use of a complement inhibitor are at increased risk for meningococcal disease even if fully vaccinated. This patient should be given a series of MenACWY vaccine, MenACWY (2 doses separated by at least 8 weeks) and a 2- or 3-dose series (depending on brand) of MenB vaccine. The patient should receive regular booster doses of MenACWY and MenB as long as he remains at risk: a booster dose of MenACWY every 5 years and a booster dose of MenB one year after completion of the primary series, followed by a booster dose of MenB every 2–3 years thereafter.

Because patients treated with complement inhibitors can develop invasive meningococcal disease despite vaccination, clinicians using Soliris or Ultomiris also may consider antimicrobial prophylaxis for the duration of complement inhibitor therapy.
