The Pfizer coronavirus vaccine is a novel kind of vaccine, which works somewhat differently in its mechanism from others.
Most vaccines work by implanting a denatured or somehow otherwise inactive bit of the targeted virus into the body; the body then produces antibodies to destroy it, and thus learns how to fight it, and will produce antibodies for the real virus if it encounters it in the future.
This one is different.
The main ingredient in the Pfizer vaccine is mRNA, or messenger ribonucleic acid.
RNA molecules are coded for various kinds of proteins the body produces; RNA is related to DNA, deoxyribonucleic acid, the building block of life, of gene expression, etc.
So, this messenger RNA codes the building of a portion of the coronavirus; that is, it tells the human body how to make a bit of the coronavirus: it instructs the body to do so, then the body does so.
Then the usual sort of vaccine functionality takes over: the body sees this as a foreign matter, and produces antibodies to deal with it, and hopefully then knows how to produce those antibodies to fight off the real virus if it ever encounters it.
I have chemistry background, not biology or biochemistry background per se, so I’m no expert in these matters. But I do know a bit about the drug approval process, which normally takes years.
But the little I know about biology, is enough for me to find this disturbing.
Isn’t it eerie and strange that we’re getting the human body itself to produce the simulacrum of the coronavirus, rather than producing that simulacrum of it outside and using it as a traditional vaccine?
Isn’t using RNA potentially dangerous; do we really know what we’re doing? Have we ever created a vaccine of this nature before?
I’m wary of using something so close to DNA, worried about side effects.
If people who have contracted the coronavirus and successfully recovered from it have developed antibodies to fight it off, why not, if we must use RNA to build anything, get RNA to build such antibodies? Or why can’t we take antibodies from such people, if they still have them in their system, and transplant them into people as vaccines?
I think there’s nothing wrong with being wary of this new technology, and I’m not an anti-vaxxer, per se; I get the flu shot annually, and haven’t suffered any ill effects from so doing, but I am disturbed by this new vaccine technology. We were told that it had been impossible to create a vaccine for SARS; now suddenly we have one for this coronavirus? Why should we believe it’s ready, that the clinical trials weren’t rushed, that they had enough time, despite how long the drug approval process normally take for this kind of thing, i.e. years?
And yet my provincial government’s premier has said that while voluntary, anyone who refuses to take the vaccine could find themselves shut out from entry to various public places, e.g. government offices, shopping malls, doctor’s offices, etc.
Why must we all be hurried into taking this, an unproven, new experimental vaccine technique, for a disease with a 99% recovery rate?
And be treated like lepers, unpersoned if we question it and refuse to comply?
