I'm sure there will be a heap of psychosomatic reactions to the vaccine, and moreover it will be blamed for everything from hairless to impotence to excess belly fat to ingrown toenails to cancer in your 80's to vertigo to menstrual bleeding to jock itch and everything else in between.
If someone weighing 300 kgs has a heart attack within cooee of having a vaccine shot, the vaccine shot will get the blame. In fact, have any adverse health event within cooee of getting the vaccine, and the vaccine with get the blame.
There are a group of people - and many of them will be Q Anon believers (= tinfoil hatters) - who believe that the vaccine is designed to either control you or kill you, and the anti-vaccine stories will become more and more lurid unfortunately.
The same people who tell you that the virus is not dangerous will be the same people who are illogically injecting themselves with bleach or taking Ivermectin or trying to get light into various orifices.
