No, the unvaccinated population, where the virus keeps being replicated, breeds variants of all kinds; the vaccinated population applies selection pressure that favors vaccine resistance. If the entire population is vaccinated variants would not emerge at all because the virus would not spread from person to person (and would eventually disappear from the population).

Sadly, the ZeroCovid ship has sailed. Vaccines do not prevent infection or transmission (1). All vaccines appear to do is to (hopefully) dull the severity of the infection once you've got it. Plus now we have animal reservoirs, and no way to vaccinate those. Edit: (1) Obviously we should talk about the degree of infection and transmission reduced by vaccines, and not in black/white terms. I haven't seen conclusive data, just the Israel Delta charts that are not particularly encouraging.

  Please stop spreading disinformation. Vaccines have been shown in many, many studies to reduce the spread of COVID-19.

    [Fair enough, reformulated for better nuance.] Sadly, the ZeroCovid ship has sailed. * Covid vaccines only partially prevent infection or transmission. To the best of my understanding even 100% vaccination cannot prevent outbreaks. * We live in an 8bn people world + God know how many animal reservoirs. It is logistically impossible to vaccinate every living being susceptible of covid infection. We've got to live with endemic covid. * Fortunately the toll on children and teens is very small, and the vaccines do work best in preventing severe cases across the entire population, which makes living with endemic covid a whole lot more palatable. At some point we have to face the unavoidable. There will be variants, there will be outbreaks, hopefully the impact will be bearable. https://www.healthline.com/health-news/heres-how-well-covid-19-vaccines-work-against-the-delta-variant https://www.healthline.com/health-news/heres-how-well-covid-... https://www.nature.com/articles/d41586-021-00396-2 https://www.nature.com/articles/d41586-021-00396-2 https://www.cnbc.com/2021/08/12/herd-immunity-is-mythical-with-the-covid-delta-variant-experts-say.html https://www.cnbc.com/2021/08/12/herd-immunity-is-mythical-wi... https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1016465/Vaccine_surveillance_report_-_week_36.pdf https://assets.publishing.service.gov.uk/government/uploads/...

My understanding is that the delta variant originated in India. I’m not convinced that achieving a 100% vaccination rate in the US would accomplish anything.
