I don't know why they're surprised.
The "vaccine" doesn't stop transmission, doesn't do away with the mandating of masks (which do not work), doesn't do away with any of the conditions that dem administrations force on their constituents, and doesn't protect an individual nearly as well nor or nearly as long as natural immunity from having the virus. Not to mention the ugly cast of characters involved.
There is literally no incentive to get it, unless one is terrified...Which is one of the reasons they've been terrorizing the population over covid.
On the other hand, as politicised as the democrats and leftists have made covid, vaccines, masks, and the like, there is PLENTY of incentive NOT to get it.
That's one big reason those assclowns have to try to mandate it and get pushy about it.
