Sorry I wasn't clear: I have read about Marek but what I didn't find is can it happen with COVID vaccines or not.

  Oh, gotcha. Here's a source that might help. > 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. https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002198 https://journals.plos.org/plosbiology/article?id=10.1371/jou... Basically, it all comes down to whether or not the vaccines prevent transmission. If they do, we're all good. If they do not, we might be in trouble. It looks like they do not.

    @raphlinus posted a link from the author of the Marek study, apparently he's not worried about it. https://theconversation.com/vaccines-could-affect-how-the-coronavirus-evolves-but-thats-no-reason-to-skip-your-shot-165960 https://theconversation.com/vaccines-could-affect-how-the-co...

      And there's others who are worried. More to your point, though, I'm more interested in the peer-reviewed stuff than op-eds.
