What should be compared are the adverse affects from these "vaccines" to other vaccines. There have been more adverse affects to these "vaccines" than all of the vaccines combined since vaccines were developed.
RE: Where do you get your information that the “vaccines” have prevented the spread of the virus.?
I am not saying that the vaccines are 100% effective. Even Pfizer, supposedly the most effective, gives a 5% chance of you still catching the virus. For every 100,000 to take the shot, there could be 5,000 still infected.
Remember — the title of this thread is about PROBABLITIES.
There will be tragic cases like the 19 year old you mentioned, but there will be far, far more people who are protected by the vaccines.
BTW, this is not to say that we might not have LONG TERM effects of those who have been vaccinated. It’s still too early to tell.
Such is life. There are no absolute certainties, only risk calculations we must all make.
