Moderna invented a new way of making vaccines in late 2010’s and Pfizer did likewise. It got patented. All they had to do was to wait for the right pandemic, prophesied by Anthony Fauci in the beginning of Trump’s presidency: He will have to deal with a “surprise outbreak”. The opportunity came with the outbreak of COVID-19, and within 10 days Pfizer and Moderna had a suggested vaccine ready to be mass produced. President Trump jumped at the opportunity to develop it at “warp speed” by promising to buy the first few million doses whether they worked or not. To further speed it up they skipped the animal steps and went directly to human subjects, whether pregnant or not. The initial few months looked promising, so one week after the 2020 election the vaccine was approved for emergency use. (It takes 9 months to complete a pregnancy). The first doses were administered mid December , and the VAERS results were evaluated, and Pfizer compiled the data up to Feb 28 2021. The results were publicized internally Apr 30, 2021 and subsequently shared with the White House senior staff, including the Surgeon General. The White House freaked out and held a number of emergency meetings, and May 21 published comforting words that there was nothing to be afraid of, the vaccine is working perfectly as designed.
Be that as it may, here is the Pfizer report as of Apr 30 2021.

This is the opposite of the truth: “It should have been taken off the market no later than May 21, 2021.”
If that had been done it would have cost many, many thousands of lives.
The best evidence is that heterologous vaccine boosters (“mix-and-match”) give better protection than repeated doses of the same vaccine. So if you got Moderna last time, get Pfizer this time (and vice-versa).
This is false, too: “Pfizer knew 2 1/2 months after emergency authorization of COVID-19 vaccine how deadly and debilitating it was.”
They know what they (and I) still know, that vaccination against Covid-19 is life-saving. It is neither deadly nor debilitating.
Adverse Events (AEs) are not evidence that vaccination caused harm, unless they’re disproportionate to the expected number of AEs of that type.
Serious, lasting injuries and deaths from Covid-19 vaccination are very rare, but probably not zero. There’ve been a small number of cases in which the particular circumstances suggest that unusual reactions to vaccination probably caused lasting injuries and deaths. But VAERS data does not prove it, because VAERS also includes expected occurrences of AE, which have nothing to do with the jabs.
About 24 hours after I got my second Moderna jab, I got a very sore foot. It hurt a lot, and it swelled up so badly that it was hard to get my shoe on. Do you think it was due to the vaccine jab?
I don’t. I think it was due to the nail that I stepped on.
Stuff like that happens.
But what if I’d had a heart attack, instead, or a stroke? What if I’d died? How could you tell whether it was due to the jab?
Mere temporal proximity is not proof of causality. Statistical analysis of such cases is necessary to determine whether there’s evidence of causality. So let’s do a little math.
On an average day, about 7500 Americans die, when there’s no pandemic. That’s about 0.0023% of our population.
In an average week, seven times than many die, of course.
Americans have gotten a total of about 680 million Covid-19 vax jabs, so far.
So, can you calculate how many Americans should be expected to have died within 24 hours of a Covid-19 vax jab, by pure coincidence?
The math is easy: 0.0023% of 680 million = 15,640.
Those are people who died within 24 hours of getting a Covid-19 jab, for reason UNRELATED to the jab.
(Actually, since the elderly and infirm are far more likely to get vaccinated than the general population, that number is almost certainly too low. But you get the idea.)
How about within one week?
That’s easy, too: 7 × 15,640 = 109,480.
That’s a low-end estimate of the number of Americans who died within one week of getting a Covid-19 jab, purely by coincidence, for reason UNRELATED to the jab.
Many of those are reported to VAERS, but those reports would not be evidence that the jabs caused ANY deaths unless MORE than the expected numbers of deaths occurred.
