💡NEAT PROTECTION by Measles-Mumps-Rubella (MMR) vaccine & Tetanus-Diptheria-Pertussis (TDAP) vaccine against serious #COVID19. Likely via T-cell response also cross-protects against #SARSCoV2 by 20-30%. Lesson here? Get your measles & tetanus shots too!https://t.co/JQ9qNvc366 pic.twitter.com/bkEHVfvRbH
