There are a few "buts" here. The biggest one - based on transmission rates in countries with higher vaccination rates vs the ones in lower transmission rates - is that the vaccinated (at least at first, when everybody believed the vaccine is 90+% efficient against transmission) might have engaged in more risky behavior as they felt "protected".
