Everyone getting covid and slowing transmission aren't incompatible. In the no lockdown, no vaccine world, everyone gets covid in ~100 days. With vaccines that period is a lot longer (roughly a year?) even though omicron has roughly twice as high a transmission rate. The simplest proof that vaccines have an effect on transmission is the number of infected people by vaccine status. There have been dozens of studies of this (see https://covid.cdc.gov/covid-data-tracker/#vaccine-effectiven...) but this really is one where you can just eyeball the effects https://www.nytimes.com/interactive/2021/10/28/us/covid-brea....
