None of the current quickie COVID vaccines are really vaccines in the traditional sense of a vaccine that injects target virus fragments (antigens) that the body reacts to by making protective antibodies.
Instead, what these quickie "vaccines" really are is a giant gene therapy experiment to be conducted simultaneously on billions of people. Instead of the actual target virus fragments (antigens), what will be injected is a live, laboratory-made synthetic virus/plasmid/mRNA that contains spliced-in DNA/RNA of COVID target virus fragments (antigens) so that your own body itself will manufacture the target virus fragments (antigens) when the synthetic virus/plasmid/mRNA enters your cells and hijacks their protein-production machinery, with the body subsequently producing the protective COVID antibodies to the self-made COVID target virus fragments (antigens).
Heretofore, such recombinant DNA/RNA techniques first mixes the synthetic virus/plasmid/mRNA into a bioreactor containing living cells where the synthetic virus/plasmid/mRNA invades the cells, multiplies, hijacks the cell machinery, and produces the target virus fragments (antigens) encoded in the synthetic virus/plasmid/mRNA. The manufactured target virus fragments (antigens) are then extracted and purified. These virus fragments (antigens) in turn are the only active ingredient in the vaccine when it's injected into people being vaccinated. Subsequently, the body produces protective antibodies to develop immunity to the injected virus fragments (antigens). The Flublok influenza vaccine is manufactured this way, for example (see below).
However, the "new" gene therapy technology injects the synthetic virus/plasmid/mRNA directly into people being "vaccinated", skipping the bioreactor, target virus fragment reproduction, extraction, and purification steps, and instead uses the human body directly as the "bioreactor". This is a technique heretofore never tried before, yet the plans are to try this on billions of people all at once. However, this gene therapy "vaccine" technology is not even really a new technology at all because it's been around for a while, but big pharma knew that they could never get away with such gene therapy experimentation on billions of people UNTIL COVID came along and the FDA could eliminate the bulk of their previous vaccine safety requirements because COVID emergency ...
I for one do NOT wish to participate in this experiment ...I think I'll wait a few years and see how millions of other people react first ...

This is how FluBlok influenza vaccine (a conventional recombinant DNA/RNA vaccine) is made:

The AstraZeneca and J&J vaccines are NOT mRNA products, nor are they designed to invade the cells of the body.
I do not yet believe mRNA vaccines until I see GOOD clinical trial evidence (which is needed for any vaccine anyway). But I believe that there will be at least one vaccine that is deemed safe and effective by the FDA and equivalent European agencies by January 2021 or so, with the trials published in leading medical journals.
When that occurs, I intend to take that vaccine, and to recommend that others do so. Then we can end the totalitarian nonsense that says that a STUPID MASK is as good as a vaccine, such as was promulgated last week!!!!
