This former Biden advisor is more right than folks want to admit.
IMO, it's quite apparent, given all the data with mask compliance and case rate, that cloth masks just don't work, and paper masks are worse.
We know COVID pre-delta can survive in aerosol droplets as small as 8 microns a while. That cloth mask you wear, the smallest hole is 80 microns, if fitted tight. The "surgical" masks have giant holes on the sides, nose, and bottom, so when you talk, breathe, or sneeze, it shoots out all those sides, the mask doesn't magically absorb it. The surgical ones act like an open fire hydrant and cloth masks simply further aerosol it. For cloth masks, it's like taking a hose to a chain-link fence claiming the water isn't getting to the other side.
I believe the mandates are just to make people think they are doing something, that the government is doing something. Just a safety blanket. Nothing more.
But let's say they do work, then masking vaccinated people makes zero sense. Aside from the J&J, the vaccines only protect against one spike protein. This is why the head if the CDC in Feb-April was fighting the administration asking vaccinated to still mask, she went on CNN complaining about it, saying not just you are taking away the carrot, but you are stopping vaccinated people from developing full immunity to COVID via exposure. This way we see what we are seeing now, but to a lesser degree, vaccinated people by a large proportion (99.9%) either being asymptomatic or have mild symptoms for 1-2 days. Very few breakthrough cases. Breakthrough meaning severe not any case. They get antibodies for the four main spike proteins and develop a strong t-cell response.
Masking vaccinated people (if you believe it works) makes the vaccine ineffective as the first mutation against that one protein is going to go nuts and be a repeat of Fall/Winter 2020 as nobody would be immune to it. The CDC knew this, but the months idiots kept saying vaccinated still had to wear masks would do nothing but prolong the epidemic.
So in the end, even if you believe masks work, they are counterproductive to the end goal here, getting this to an endemic disease.
