What I saw were Novavax and AstraZeneca on the quick glance. Stick to doing… whatever it is you paralegals do dailyWhere did I claim it was? I linked the article, pointed out the 88% effective rate for Pfizer, and then provided the direct quote from the paper that said that.
Back to the short bus with you!
Solid refutation on Reuters part. Two real bastions of credibility in the public eye these days. They should have included a WHO quote for the hat trickBecause someone linked the Indiana doctor earlier today.

At the 00:46 mark (here), the man says that COVID-19 and other respiratory viruses are “spread by aerosol particles, which are small enough to go through every mask”.
The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) say ( here here ) that wearing a face mask can help protect yourself and others from spreading the virus. This should be combined with other methods of prevention such as frequent handwashing and social distancing.
What a douche comment.
I am no expert myself but I do deal occasionally with Breathing Air and all the time for general compressed air filtration applications., including NFPA99 standards for hospitals at times. The particulate size matters and one must (obviously) consume a set volume of O2 to live. You have 2 masks, you still try and consume the same volume of air by exertion. Those particular micron particles are inhaled and this extra exertion in trying to consume the needed oxygen to live just creates more vacuum to pull thru the pressure drop.
Just like N95, they are only 95% effective to a certain particle size.
It isn’t my field either however I’ve made the exact same argument you are. One mask study that gets touted using video to film sneezes thru the mask settled on an aerosol particle of 5 microns… or 50 - 100X larger than the SARS COV-2 particle.You are an engineer, and I am not, but does my comment the other day hold water (pun intended). I saw @AM64 comment on the "adheres to water droplets" in another post unrelated to mine, and would it even matter if it adhered? Some quick googlefu may of showed some larger COVID rascals would be catured with an N95, but just dont see a cloth mask doing anything unless one were to cough or sneeze I suppose.
