Low Meningococcal Vaccination Rates Among Patients With Newly Diagnosed Complement Component Deficiencies in the United States.

Meningococcal vaccination is recommended for patients with complement component deficiencies (CD) in the US. In this retrospective database study, only 4.6% and 2.2% of patients received MenACWY and MenB vaccination, respectively, within 3 years of a CD diagnosis. Thus, meningococcal vaccination rates among patients with CD need to be improved.
