The efficacy numbers claimed are lies. Accurate numbers would take at least 12 months after the second jab to establish. This is very basic mathematics.
Here is the science. The flu shot has 70 years of history, in a good year it has 50% efficacy. In a bad year its 20%. Its main public health utility is that reduces the severity of infections in younger people. Who account for 1/3 of all flu deaths. The flu shot has little impact on infection rates. Just the severity of the symptoms in younger people. No real effect with older people.
All attempts at human corona virus vaccines have failed. Very low efficacy, very high rate of side effects. Human corona virus infections in an typical year will kill around 20% and 30% of the number of people who die of influenza. There is little serious data because human corona virus infections are so common and vaccines were considered a waste of time. They dont show up in the public health mortality numbers because they were never tested for.
One adenovirus flu vaccines was approved for general use. The only adenovirus vaccine in fact. It was never used because its efficacy was lower than traditional attenuated virus flu shot (by quite a bit in some people). And they were much more expensive.
So none of the current or future SARs CoV 2 vaccines will have any real impact on the SARs Cov 2 infection rates. Thats a given. But once they change the COVID testing protocols back to the ones used prior to March 2020 the number of official COVID “cases” will quickly collapse.
Because thats how casedemics work. High testing rate, high case count. Low testing rate, low case count.
Vaccination rate is completely irrelevant to the case number.
