Had COVID-19? One vaccine dose enough; boosters for all, study says

(American Chemical Society) Two mRNA vaccines against COVID-19 have proven safe and effective in clinical trials, as well as in the millions of people who have been vaccinated so far. But how prior SARS-CoV-2 infection affects vaccine response, and how long that response lasts, are still uncertain. Now, a new study in ACS Nano supports increasing evidence that people who had COVID-19 need only one vaccine dose, and that boosters could be necessary for everyone in the future.
