>breakthrough infections are very rare in vaccinated individuals.

This is simply not true. In countries with accurate tracing like Singapore and Israel, it's apparent that the vaccinated aren't significantly less likely to get infected than the unvaccinated. Check figure 10 on https://www.moh.gov.sg/news-highlights/details/update-on-loc... ; the unvaccinated only make up around 10-20% of cases. They also only make up 10-20% of the population; if the unvaccinated were more likely to be infected, we'd expect them to constitute a larger proportion of infections.
