Measles, Mumps and Rubella Vaccines Likely To Lower Risk of Severe Covid-19 Infection - News18
The Measles-Mumps-Rubella (MMR) vaccine, given during early childhood, and Tetanus-Diphtheria-Pertussis (Tdap) vaccine, given every 10 years, may help lower the risk of severe Covid-19, according to researchers. Besides eliciting a protective response against the diseases it is possible that both MMR and Tdap vaccines may also elicit cross-reactive memory T cells capable of responding to protein targets called antigens that are present in other microbes that cause diseases — including the viral antigens in SARS-CoV-2, said researchers from the Brigham and Women's Hospital in the US. Using data from more than 75,000 patients who had tested positive for Covid-19 between March 8, 2020, and March 31, 2021, the team found that patients who had previously been vaccinated for MMR had a 38 per cent decrease in hospitalisation and a 32 per cent decrease in ICU admission/death. Similarly, patients previously vaccinated for Tdap had 23 per cent and 20 per cent decreased rates, respectively, o...
