Herve Seligmann discovered that, in Israel, COVID vaccines are associated with really high death rates for a few weeks post-dose. To overcome the excess death associated with getting vaccinated, the two-dose vaccine protocol would have to fully (100%) protect you from COVID for over 12 months.
And that was back when the COVID variants were more deadly than flu. COVID variants circulating today (Omicron) are not even half as deadly as seasonal flu — making it that-much-more counter-productive to be vaccinating people against COVID.
