Those claiming side-effects from vaccination might experience the nocebo-effect instead of being malingering fakers.

According to this study, those complaining about side-effects from vaccinations may experience nocebo-effect.

I always figured that the whiners were just faking. I personally do not know anyone with adverse reactions.

We (my friends) came to the conclusion that those complaining just wanted the rest of the day off and all of tomorrow. We figured that it is better to let the fakers take off rest of the day and the next day rather than have the fakers be out weeks with the 'Rona, or have to replace them because they died.

When I got my shots, I considered pretending to be sick the next day, like the fakers, but decided not to do so because the boss might find out and fire me.
