Do you have a source for that? This is the first time Ive heard someone call it a hoax that was an antivaxxer. Most antivaxxers are hesitant due to the speed at which the vaccines were made, the new technology used to make them, and the fact that the companies making them can’t get sued if they kill people.
There are those type too, yes, but there are also people who think Covid is a hoax, or at least that its danger has been drastically exaggerated. There tends to be a lot of overlap between beliefs here.
So no source. Interestingly if you look up the list of global epidemics however COVID is #6 of 20, and if you sort by total global population list, COVID is #11. So it seems we have actually had worse pandemics. Maybe you’re seeing people reading the actual stats?
