Long-term measles-induced immunomodulation increases overall childhood infectious disease mortality

TLDR

Measles vaccination protects against measles and offers additional health benefits beyond lifelong immunity. The study examines whether measles‑induced transient immunosuppression leads to a 2–3‑year loss of immune memory, affecting mortality from other childhood infections. The authors analyzed mortality data collected since the introduction of mass measles vaccination in high‑income countries. Measles vaccination is linked to lower mortality from other childhood infections, and measles appears to disable immune memory for 2–3 years, preventing other infections from exploiting this damage.

Abstract

Extra dividends from measles vaccine Vaccination against measles has many benefits, not only lifelong protection against this potentially serious virus. Mina et al. analyzed data collected since mass vaccination began in high-income countries when measles was common. Measles vaccination is associated with less mortality from other childhood infections. Measles is known to cause transient immunosuppression, but close inspection of the mortality data suggests that it disables immune memory for 2 to 3 years. Vaccination thus does more than safeguard children against measles; it also stops other infections taking advantage of measles-induced immune damage. Science , this issue p. 694
