In layman's terms, some batches of the vaccine seem to be more toxic/deadly while other batches aren't AS toxic/deadly. And according to the data their seems to be a pattern of toxic vax being dispensed then not as toxic vax being dispensed and they repeat that back n forth over and over. That's because they have to spread the extremely toxic vaxes out with breaks in between so we all don't notice a MASSIVE die off/adverse effects and/or they're trying different ingredients with each batch.
