"A large-scale study in the U.K. investigating breakthrough infections has found that out of 1.2 million people who received a first dose of the COVID-19 vaccine, only 0.5 per cent subsequently tested positive for the virus, encouraging evidence of the vaccine’s effectiveness.
The study also found that those who had one or two doses had significantly lower odds of severe disease or hospitalization than unvaccinated people if they contracted the virus — and a lower chance of experiencing long COVID symptoms."
