For all those who still believe herd immunity as a concept applies to SARS-CoV-2: It doesn't. We'll be infected again and again, and the data now tell us that the risk of serious long-term effects increases with each infection. Govts need to re-think & find a new & better plan 1/

"the risks were evident in those who were unvaccinated, had 1 shot, or 2 or more shots prior to the second infection"
This figure shows clearly that we cannot rely on vaccines to protect us from serious sequelae from COVID. 2/

This is a massive study with a cohort of people with first infection (n = 257,427), reinfection (2 or more infections, n = 38,926), and a non-infected control group (n = 5,396,855) to estimate risks and 6-month burdens of all-cause mortality, hospitalization, and organ sequelae3/

Thanks & congrats to @zalaly et al for another important contribution to the field. They state:

"Reducing overall burden of death and disease due to SARS-CoV-2 will require strategies for reinfection prevention."

Time to change our ways. #letsdoit
