> What's the harm in letting unvaccinated people spread covid amongst themselves? Vaccinated people aren't at risk. Yet > The only concern in theory is that a vaccine-immune covid variant could develop amongst unvaccinated populations. Is there any evidence for that though? Every human with covid is a variant factory. Even the vaccinated are. And every variant is a new fire which could burst out again - there was a comment that "Everytime we open up, there's a new variant", as if the variant spike was somehow unrelated to the opening up. This isn't theory. We should somewhat be thankful that vaccines work with Delta, because if the variant on the uptick was the Gamma variant, the acquired immunity wasn't as effective at preventing a severe disease [1]. If the virus isn't eradicated, then it will keep making comebacks as newly infected people provide more opportunities for more "successful" variants. Also kids, don't forget kids. Some of them are babies. [1] - https://wwwnc.cdc.gov/eid/article/27/10/21-1427_article https://wwwnc.cdc.gov/eid/article/27/10/21-1427_article
