He is ruining his career for this, but a couple things to say before canceling him like this
First of all he it’s not a matter of him thinking vaccines are bad or useless, what he is against is against the enforcement of it, he just wants to have a choice, and I understand that, not share it at all ( actually think vaccines should be mandatory ), but I can see a logical reason behind it even if I don’t agree.
Second of all he is not scared of the vaccine, actually tried to get the vaccine in Brazil Airport to be able to go in the country, but they told him that even with that he had to wait.
And again even you hard disagree with him as I do, I respect him for wiling to sacrifice everything just for his personal ethics
