Current vaccines are non-sterilizing and therefore do not effectively stop the spread/transmission of SARS-CoV-2 (the virus) but is very effective at preventing the disease the virus causes (COVID-19). Initially the vaccines were able to keep viral loads low enough to meaningfully stop the spread, but the Delta variant resulting in far higher viral loads and removed that advantage compared to the original virus.
Arguing that the infection rates are uncorrelated is one thing, but serious illness and death is what we really need to care about with this virus. And for those metrics, vaccination is highly-correlated to better outcomes.
