My take on the vaccine crap:
Its actually worse than even the small claims of effectiveness that are being made..... all the studies assume you wear the mask for a short time before exchanging it for another mask.
These masks were NEVER designed to be worn multiple times for hours on end. They are supposed to be exchanged because they collect and trap bacteria over time and yes, that is for the N95 masks which are multiple times more effective than the cloth or improvised masks we see most people wearing.
