Look on the bright side, at least Covid19 might eradicate the antivaxxers. And, if you are an antivaxxer, stand up for your principals and refuse the Covid19 vaccine when it comes out, otherwise you are totally full of pointless shit.
But, I am sure there will be enough to go around, enough even for the antivaxxers, of course. What will happen, is that they will take the vaccine and then they will go on sprouting their usual rubbish about vaccines, of course they will.
Forgive them for they don't know what they do... say... understand.
