No, the vaccines are not being produced one at a time - that’s a stupid theory. They have giant facilities where they are making thousands at a time, just like every other vaccine or medical product or large-scale-manufactured item of any kind. The persob who originated this was certainly not involved in pharmaceuticals manufacturing as they claimed or else they wouldn’t make such a preposterous suggestion that one dose of the vaccine is being made at a time which therefore makes it impossible. That is full retard.
