Sorry you’re right. I only read your initial post and replied to that. As for your follow up questions, I’m probably not the best person to ask. I’m a chemist with some knowledge of biochemistry, so while I understand the protein synthesis mechanism pretty well, more technical issues surrounding the vaccine are not within my realm of expertise.
With that disclaimer , my understanding is that it is only the spike protein that is encoded by the vaccine mRNA. Whether it’s 109% accurate or not, I am not sure. It’s accurate enough to elicit immune response that is effective against the virus, as shown in the clinical trials.
As for the composition of the vaccine, I believe it’s the mRNA, preservatives, and lipid nanoparticles designed to facilitate transfer of the mRNA through the cell membrane. There may be other ingredients; I truly don’t know.
I truly can’t even venture a guess on your third question; I have no idea what the infection mechanism of the virus is, nor any knowledge of what differences are present in the variant forms of the virus.
Antibodies typically are mostly harmless to human tissue. There are some with autoimmune disorders for whom this is untrue. Again this is far outside of my expertise, but the effects you mention on sperm counts and motility were among men infected by the virus. There’s no reason to think that whatever effects turn out to be confirmed were caused by or related to antibodies rather than effect of the viral infection. If it’s infection rather than antibodies causing the effects, then vaccination would tend to reduce the prevalence of them.
Again, though I’m certainly not the best person to ask about this, and I’ll gladly defer to any of the medical professionals who have already been posting on this thread if they have different/better answers.
Amongst these are important questions I know they can not answer, nor can anyone at this point. The data is not there. The studies have not been done.
As a society (the developed nations) with falling fertility rates as is, I fear this thing is a fools rush in kind of thing. The scary goals articulated by some of the people involved in the vaccine as to world population are not some silly concern, not when there is some data pointing to issues with sperm viability and other small data pointing to some sort of immune reaction to placental tissue.
On the ingredients and what the genetic structure of the mRNA is, they rely on the label and literature.
As is, gas_dr has provided me with good insight as to the vaccine and me, my wife and parents/inlaws taking it. None of us are of child bearing age so my deeper concerns do not apply.
