Nothing can be definitely proven. However, if adverse reactions occur and fall within the parameters they should be properly reported and investigated in name of science.
There’s a chance of injury with any medication we take 1 in 10,000. 1 in 100,000 etc. Obviously, the disease control specialists believe the pro’s out weigh the cons. More lives saved but acknowledge there is going to be some collateral damage with a very small percentage of the population. Hence, that’s why several governments worldwide have initiated a Vaccine Injury Support Program to compensate those that have high likelihood their injury was caused by the vaccine. I’m just saying it’s a well kept secret or not we’ll communicated throughout the general medical community aka family physicians.
Recently there have been some articles coming out about the VISP and people’s claim’s. If properly reported time will tell if there’s trends.
We likely won’t know the extent of long and short term injuries for years to come.
