A (preprint) study published today by researchers at nference and the Mayo Clinic looked at the genetic variation of breakthrough infections versus infections in unvaccinated patients and found that the viruses in breakthrough cases had significantly lower diversity. Per the abstract, this suggests that COVID-19 vaccines also restrict the evolutionary and antigenic escape pathways available to SARS-CoV-2.[0] [0] https://www.medrxiv.org/content/10.1101/2021.07.01.21259833v1 https://www.medrxiv.org/content/10.1101/2021.07.01.21259833v...
