The virus will keep spreading regardless of vaccination status. We are already well beyond herd immunity levels when vax and infection are taken into account; unless you don't want to believe Fauci first herd target level, before he shifted the goalpost again. The CDC could have done so much better on publicizing information that would have resulted in better outcomes. They have known all along that the vaccine didn't prevent infection; that is precisely why they stopped tracking breakthrough cases. They knew if they continued to track them, the data would reveal itself.
