Right. The vaccines are contributing to "variants". Think, where do viruses come from ? They come from any living cell. You acquire the virion (transmission) from patient zero and then you pass it on to others. Now, you take a "vaccine" which is actually an mRNA manipulator so that you build "spike proteins" in which science is predicting that it'll be the same as the covid19 spike protein. This triggers your intracellular immune system to attack it, but remember, it's your spike protein, it's not from covid19. If this spike protein adapts to another person with a different vaccine, the end game is a variant, which will be lethal to you and everyone else. This is what happened to Dr. Kapila from New Jersey who went to help his brother in law in India, but a variant killed him instead.
