Batman:
I have personally discovered a few antivax social media forwarders who are actually vaccinated. True story
:( yes I know these people personally. Have told them to stop posting. But the damage... They think it's funny.
I think some people have issues with experts or authorities telling them to do anything... so they take the opposite stance by default.
But, they also might be overweight with high blood pressure and in their 50's with a higher chance of dying from covid, and long covid not much fun either . And, despite their arguments, they know the vaccine works. The evidence is too strong to debate.
One of my UK friends tested positive to covid yesterday , sweats, aching ribs, fever, cough, but, at this stage, just fine. Whole family has it, including kids, so he caught off them.
Its a shame the vaccine didn't offer more protection against infection.
