Much less BCG or variola (pox).
Viruses like flu and coronaviruses, nigh impossible to eradicate.
1 and 3, sure. And mRNA vaccine is not particularly more dangerous than any other type. The cost-benefit is strongly on the side of vaccination there.
Unfortunately, there is evidence that trials under-state risks. Evidence for this is:
1. Safety notices for the vaccines have been edited post launch to start talking about risks of heart inflammation and other problems, which were not detected by the trials but are now common enough to justify people being warned about them.
2. Drug trials appear to regularly understate the scale of side effects and nobody can figure out why: https://sebastianrushworth.com/2021/07/19/do-drug-trials-und...
Additionally, the trials never formally completed, cannot now complete because the control groups have been vaccinated, and some of them excluded whole groups of people e.g. pregnant women, children and in some cases the elderly!
This leads to an absurd situation in which the US CDC is saying that the vaccine is safe for pregnant women simultaneous with Moderna starting trials in pregnant women (who were previously excluded).
And finally, putting all those problems to one side, the issue is actually relative risks. Even if the risk of a vaccine is low, even if similar to or higher than the risks of the thing it's trying to vaccinate you against, it may not make sense to take it. That is just basic cost/benefit analysis.
mRNA vaccine is not particularly more dangerous than any other type
I don't understand how that is consistent with the data from the various vaccine surveillance systems which show clearly that it's drastically more dangerous. It's also inconsistent with anecdotes that I've been hearing from people around me, of whom a disturbingly large number say that the vaccines made them very sick (i.e. they describe symptoms similar to that of COVID itself).
I read a lot of your other comments so far and I had a suspicion, but this lone comment of yours confirmed it for me. You have some basic internal fear of the vaccine so you've done a bunch of rationalizing to make it seem worse and confirm your own bias.
I've looked at the VAERS data this morning for the US and you have a much higher chance of getting hit by a car and dying, or as is the very prescient case, getting COVID and having more adverse affects from that than an adverse vaccination, but I'm not going to convince you of anything because of that basic fear you have.
a. Not very charitable.
b. Not the simplest possible explanation.
Occam would not approve.
