Supposedly the majority of vaccine adverse effects have come from 5% of the batches. These batches are definately not created equal. If a medical-cabal-dictatorship was trying to kill everyone, wouldn't they want to get as much data out of them as possible? One way to do that is to subject the whole population to experimental drug trails. Why would you stop at testing just one drug? So the theory is that in each vaccine is a cocktail of drugs that differs from batch to batch. By recording what batches people got, and requiring anyone who wants to recieve other medical services to have that data associated with them, you can look at their future medical history to determine the long term outcomes of the cocktails they've recieved. So the people who had their limbs turn black and rot off got one hell of a bad drug. They are being reckless with your health, and that is to be certain. Why not aquire a lot of data out of people if you are willing to be completely reckless with their wellbeing?
