Moderna & Pfizer/BioNTech are testing mRNA (synthetic RNA)vaccines to be rolled out experimentally on millions of people around the world using synthetic RNA mRNA vaccines are a genetically modified biohack on the human body to produce part of a virus

A handful of animal trials performed by the vaccine makers
looked overall at the tolerability of the vaccines clearance of pathogens from the upper & lower respiratory tract to probe for which dose level might be immunogenic & safe. https://doi.org/10.1038/s41586-020-2607-z

Animal trials are being conducted alongside & not before human trials & data regarding the results of possibility of pathogenic priming which could lead to enhanced COVID-19 disease & potentially cause autoimmunity against many human protiens....cont

As it is not known if any of these vaccines has eliminated unsafe epitopes, then if the immune system produces antibodies to these epitopes they could attack “self,” the hallmark of autoimmune disease

Although any logical person would consider it very wise to wait for results from Phase III protocol of Pfizner COVID vaccine trials the governments of England, Scotland, Wales & Ireland are indeed hyper maniacally keen to roll out ....cont

& put into the bodies of millions of people in Britian rushed vaccines as an unsafe stategem that may result in idiopathic antibodies allowing the target virus to enter cells & replicate causing an autoimmune wild tinder box effect against a virus that causes ...cont

little or no effect in cira.99.3% of the British Population.This clearly is a very dangerous stragety which is the opposite of protecting someone from an infection. ADE ( antibody-depent enhancement) causes the vaccinated person to get a worse case of the disease ...cont

ADE among much larger swaths of literature, has also been demonstrated in studies on SARS CoV in humans, ferrets (liver damage) &non-human primates (acute lung damage)
https://en.m.wikipedia.org/wiki/Antibody-dependent_enhancement
https://en.m.wikipedia.org/wiki/Antibody-dependent_enhancement
A very recent review of ADE concludes rigorous clinical trial design and postlicensure [sic] surveillance should provide a reliable strategy to identify adverse events, including the potential for enhanced severity of COVID-19 disease, after vaccination.” https://pubmed.ncbi.nlm.nih.gov/33077678/
Governments are rolling out a rushed vaccine of which trial stage III protocols do not end for another 2yrs & it's not known what percentage of the population may suffer pathogenic priming or ADE after vaccination with a COVID vaccine. https://www.autoimmuneregistry.org/autoimmune-statistics
It is estimated that over 4 million people in Britian already have an autoimmune disease & therefore are likely more susceptible to pathogenic priming & ADE.
A long side of which Moderna & Pfizer/BioNTech are using recombinant vaccine technology, producing a genomic chimera with properties intended to both activate the immune system and generate antibodies to the SARS CoV-2 spike protein. https://www.britannica.com/science/chimera-genetics
Astra-Zeneca/Oxford is using a chimp virus an adenovirus that can be the cause of the common cold combined with the spike protein from SARS CoV-2. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31604-4/fulltext
There are long-standing concerns about primate viruses in vaccines ever since the polio vaccine administered from 1955 to 1963 was linked with cancer. The polio vaccine was cultured in primate kidney cells infected with Simian Virus 40 (SV40).
Johnson & Johnson who were found guilty of aluminium being their baby poweder product, are using a human adenovirus combined with the spike protein. https://www.medrxiv.org/content/10.1101/2020.09.23.20199604v1
GlaxoSmithKline/Sanofi is using a recombinant antigen based on their flu vaccine technology.

Warning flags have been raised about COVID-19 vaccine candidates that use adenoviruses that could result in an increased susceptibility to HIV infections based on previous findings. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)32156-5/fulltext
In the Moderna and Pfizer mRNA vaccines there are also other ingredents that raise concerns & need to be watched very closely. https://en.m.wikipedia.org/wiki/Polyethylene_glycol
Many people could have allergic, potentially deadly, reactions to a PEG-containing vaccine. PEG antibodies may also reduce vaccine effectiveness.
Pfizer's inserted in its vaccine an ingredient mNeonGreen of which its toxity in vaccines is unknown,an ingredient derived from a marine invertebrate has bioluminescent qualities for medical imaging purposes it's unclear why an injected vaccine would need a visual day-glow marker
The GlaxoSmithKline vaccine will have a well known toxin adjuvant used in the H1N1 vaccine that was linked with narcolepsy and cataplexy. It contains squalene which is harvested from shark livers & effects female repeoductive organs . https://pubmed.ncbi.nlm.nih.gov/8473002/
As well as permitting or activating of the passage of substances into, out of, or through cells, or from one cell to another. https://cancerres.aacrjournals.org/content/25/5_Part_1/764.abstract
AS03 also contains polysorbate 80, which disrupts the normally protective blood-brain barrier. https://www.sciencedirect.com/science/article/abs/pii/0378517389902664
And, tocopherol used in vaccines a form of Vitamin E, as an emulsifier. https://www.sciencedirect.com/science/article/pii/S0168365919306066
Pfizer & GSK are using saline placebos in their trials, Astra-Zeneca/Oxford is using a meningitis vaccine as its “placebo,” The meningitis vaccine causes significant levels of adverse events & its reported may have even caused the death in the Astra-Zeneca/Oxford trial volunteer.
Astra-Zeneca/Oxford state the “use of saline as a placebo would risk unblinding participants as those who had notable reactions would know they were in the were in the ChAdOx1 nCoV-19 vaccine group.”Astra-Zeneca/Oxford have 1 saline placebo trial plsnned in South Africa...cont

so hopefully there will be safety data compared to a real placebo when that trial is completed in a few years. https://clinicaltrials.gov/ct2/show/NCT04444674?term=NCT04444674&draw=2&rank=1
