Maybe I'm jumping to conclusions here, but I'm just trying to research this and really trying to comprehend if I'm right or not.
Like, Elon has stated stuff that's borderline antivaxx, among other things, and his stans eat it up like it's candy.
Probably, most anti-vaxxers are pretty unhinged as are most people who look deeper than the CNN Money profile of Musk and don't just realise he's a charlatan who got lucky/was a con artist during the dotcom bubble and now he pays people smarter than he to implement the utterly banal 1960s/1970s ideas his companies are centered around (reusable space rockets, electric cars, etc)
That said, personally I am one, but that's for different reasons than most. I just happen to have been big into the clinical trial software space once upon a time, made loads by being good at stats. It's still a good idea for people with health problems, people over certain ages (varies by country how soon/late might make sense), people who interact with those categories daily, etc. But for plenty of people there's just not a moral or logical basis for mandating its injection into their body as a precondition for anything in particular. It's just no effective enough and presents enough risks for especially younger people to where recommending (and especially mandating) it to certain groups just makes no sense (unless you stand to profit from a significantly increased number of people who have to take it..)
One thing I don't understand from the super pro-pharma crowd lately is the denigration of vaccine monitoring systems like VAERS? Its existence is the entire basis for Pfizer's FDA filings - if there were problems it would be apparent in the VAERS data according to them...
