I might wait for a full authorization from the FDA to get the vaccine, I bet the EUA gives the manufacturers extensive liability protection and the vaccine might not do me any good. I have never suffered from influenza or have had headaches or fever for a very long time.
As far as I know, the vaccine doesn’t prevent infection or transmission of the virus so mutations are likely to still happen, it just prevents the virus from causing the disease much like other vaccines. The vaccine manufacturers wouldn’t have reliable data if none of the test subjects tested positive for the virus.
Mask effectiveness is based on the virus being an aerosol and the mask being sealed against the face which most are not. I do think a lot of questions about the effectiveness of the vaccine should be answered in the next month
It is true that they don’t get data on transmission from the trials, those are for safety and efficacy. The transmission data is done retrospectively and is coming in now. Currently there are 5 published studies on the mRNA vaccines re: transmission and they reduce transmission by 70-90%
