Denis Rancourt on the effectiveness of masks

  • Science has already proved that masks don’t work.
  • Many large Randomised Control Trials (RCT) and meta-analyses over the past decade show masks offer no reduction in risk from respiratory viruses.
  • We understand the mechanism of transmission of respiratory disease and the science is clear that masks can’t work.
  • It can’t help others when you’re breathing out and it can’t help you when you’re breathing in.
  • The mechanism of transmission is through very small aerosol particles.
  • Any opening in the mask will allow enough of the minimal dose to infect you.
  • One of the effects shown in studies with healthcare workers is that they had an increase in headaches.
  • Many articles in support of masks are not relevant e.g. masks stop droplets but transmission is not via droplets.
  • Diseases are seasonal because droplets are carried for a long time when the air is dry like in the winter.
