It would seem to me that some caution as to the new mRNA-type vaccines is warranted. This is not to be confused with anti-vaxxer CT nonsense generally. Because conventional vaccines have an very extensive history, have been used billions of times over the course of a century or so, and have been extremely intensely studied, investigated, discussed, debated, litigated, etc. etc. But mRNA technology is relatively new. Per Wikipedia:
Up until 2020, these mRNA biotech companies had poor results testing mRNA drugs for cardiovascular, metabolic and renal diseases; selected targets for cancer; and like Crigler–Najjar syndrome, with most finding that the side-effects of mRNA insertion were too serious. mRNA vaccines for human use have been developed and tested for the diseases rabies, Zika, cytomegalovirus, and influenza, although none of these had previously been adopted for widespread use. Many large pharmaceutical companies abandoned the technology, while some biotechs re-focused on the less profitable area of vaccines, where the doses would be at lower levels and side-effects reduced.
Before December 2020, no mRNA drug or vaccine had been licensed for use in humans, but both Moderna and Pfizer/BioNTech were close to securing emergency use authorization for their mRNA-based COVID-19 vaccines, which had been funded by Operation Warp Speed (directly in the case of Moderna and indirectly for Pfizer/BioNTech). On 2 December 2020, seven days after its final eight-week trial, the UK’s MHRA, became the first global medicines regulator in history to approve an mRNA vaccine, granting “emergency authorization” for BioNTech/Pfizer’s B"Verbeke_2019"62b2 COVID-19 vaccine for widespread use. MHRA CEO June Raine said “no corners have been cut in approving it”, and that, “the benefits outweigh any risk”.
So this is a technology which has never been found to be safe or effective for humans, and is being pressed into use due to the severity of the pandemic. In particular, the longer term effects of doing this would seem to be impossible to gauge.
Leaving aside whether it’s the right thing for the governments to roll out mass vaccinations under these circumstances, where it comes to a head the decision of each individual as to whether to take it.
As an example, I myself have already had covid, and I probably already have most or all of the benefits that might be conferred by vaccinations, and taking it would largely be just a civic exercise of some sort. I’m not in any rush.
