Steve Kirsch at his substack blog makes the point that once upon a time would be obvious, that if the Covid vaxxes worked, one would only need one shot. Certainly, for other vaccines such as tetanus, a booster is given after say a decade, but that is different from having to get one every few months, with no end in sight. And tetanus, also rare, has more devastating effects than most cases of Covid in young, otherwise healthy people. There are no other vaccines on the market, apart from the protected Covid ones, which kill more people than they save.
