It is pretty obviously so, and it's also not controversial really. e.g. https://www.channelnewsasia.com/commentary/covid-omicron-variant-vaccine-booster-delta-transmission-rate-fatal-case-endemic-2396066 https://www.channelnewsasia.com/commentary/covid-omicron-var... >Do the unvaccinated populations fuel the emergence of SARS-CoV-2 variants? > The consensus among the scientific community is yes, they likely do. Unvaccinated people have less protection from the SARS-CoV-2 virus and thus would allow more of the virus to multiply within them. > The higher rate of virus multiplication in the unvaccinated is likely to result in more possible mutations of the virus, resulting in the emergence of a larger number of variants in unvaccinated than vaccinated people. I think at this point there is not much more to say here, at least from my end. Have a great day.
