We describe the case of a patient, who presented with total IgA deficiency and partial IgM deficiency with a low switched memory B cells count, suggestive of a borderline form of common variable immunodeficiency (CVID). The role of IgA in the protection against Neisseria meningitidis, and the link between IgA deficiency and CVID are discussed. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/jmm.0.021980-0
