According to some alarmist extremists, those "placebos" are contagious and cause reporductive failure to even the unvaccinated. It just depends how deep the rabbit hole you are. Calling vaccines dangerous simply because you think they've been untested, despite numerous trials that say otherwise, means you are down the rabbit hole, but you haven't sunk low enough to the point where you think banning vaccinated people is the solution to leftists who are gradually warming up to the notion of vaccine passports.
Personally, I'm against any kind of discrimination, however there should be a line. Healthcare workers, Teachers, and anyone who works with those found more susceptible to the virus should absolutely get vaccines. Perhaps even those who work in the food industry and those in face-to-face customer service as well. Everyone else? Not so much. Still, if a company wishes to prevent themselves from being sued by someone who claims their husband got Covid and died after eating a hamburger or getting chemo, I can see why they just go ahead and make vaccines mandatory in their workplace. Unless they can afford to pay everyone looking for a handout, of course.
Which given the state of the economy, my guess is they don't.
