Recurrent invasive meningococcal infections – quantifying the risk, Germany, 2002 to 2018

The study most likely underestimated the risk of recurrent infection. Increased risk may be due to undiagnosed complement deficiencies. The high risk of re-infection argues for vaccination of patients who have survived IMD. Eurosurveillance
