PRIOR MMR OR Tdap VACCINATION MAY REDUCE RISK OF SEVERE COVID-19

Researchers in the United States have shown that prior Measles-Mumps-Rubella (MMR) or Tetanus-Diphtheria-pertussis (Tdap) vaccination may reduce the risk of severe outcomes in patients with coronavirus disease 2019 (COVID-19).

The team provided evidence that infection with the COVID-19 causative agent – severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – reactivates memory T cells previously generated by MMR and Tdap vaccination and that this may reduce the severity of COVID-19.
