It's the variants that get selected that is the long term concern. Not how or from which cohort they emerge. With leaky vaccines applied to an entire population the tendency is for more severe variants to prevail. How many times does the flu vax miss the target? Flu has is also leaky but we don't get more than 40% coverage so not likely to see more harmful strains selected. And then we whore ourselves out to big pharma hoping they stay ahead of it all. See the devastating effects of this in the poultry industry: https://www.pbs.org/newshour/science/tthis-chicken-vaccine-makes-virus-dangerous https://www.pbs.org/newshour/science/tthis-chicken-vaccine-m... And the backing study: Imperfect Vaccination Can Enhance the Transmission of Highly Virulent Pathogens "Our data show that anti-disease vaccines that do not prevent transmission can create conditions that promote the emergence of pathogen strains that cause more severe disease in unvaccinated hosts." https://journals.plos.org/plosbiology/article/info:doi/10.1371/journal.pbio.1002198 https://journals.plos.org/plosbiology/article/info:doi/10.13...
