Womp womp, looks like the current covid vaccines may very well lead to the natural evolution of far more deadly versions of covid.
Apparently this vaccine is considered "leaky" in that transmission by the vaccinated is still possible after vaccination, unlike any other vaccine used in humans, according to this paper:

But no, there's nothing different or unique about this vaccine, just TAKE IT ALREADY, so that Gravy doesn't have to come in here and pompously call you a disgusting human being who should be spit on.
"There is a theoretical expectation that some types of vaccines could prompt the evolution of more virulent (“hotter”) pathogens. This idea follows from the notion that natural selection removes pathogen strains that are so “hot” that they kill their hosts and, therefore, themselves. Vaccines that let the hosts survive but do not prevent the spread of the pathogen relax this selection, allowing the evolution of hotter pathogens to occur. This type of vaccine is often called a leaky vaccine. When vaccines prevent transmission, as is the case for nearly all vaccines used in humans, this type of evolution towards increased virulence is blocked. But when vaccines leak, allowing at least some pathogen transmission, they could create the ecological conditions that would allow hot strains to emerge and persist."
