COVID-19 vaccination reduces severity and mortality after breakthrough infections
Among individuals recently infected with SARS-CoV-2, those who were fully vaccinated had lower concentrations of almost all inflammation markers (cytokines and chemokines) than those who were unvaccinated in the short-term and long-term after symptomatic SARS-CoV-2 infection.
