Sure it did. Most of the people in the ERs with Covid were unvaccinated.
The vaccine only delayed COVID by a few months after they stopped getting boosters. And that's not counting the people who had serious reactions to it. The infection rate was much higher with the "vaccinated".
Go look at the deaths per month verses the number of vaccinated. The most deaths occurred in 2021 when the vaccine was widely available. Less people died in 2020 with no vaccine. If the vaccine worked far fewer people should have died in 2021. The vaccine was being rolled out prior to Biden taking office on Jan 20, 2021.
