Extreme opposed occasions extra seemingly in beforehand contaminated COVID vaccinees
Individuals who acquired an mRNA COVID-19 vaccine after SARS-CoV-2 an infection usually tend to expertise extreme systemic opposed occasions (AEs) than their never-infected counterparts, in line with a research printed yesterday in Vaccine.

Most (90.1% of members and 94.8% of controls) did not report testing constructive for COVID-19 earlier than vaccination.
Amongst beforehand contaminated members, the probability of extreme AEs was 2.4 (95% confidence interval [CI], 1.89 to three.09) occasions greater after receipt of the Moderna vaccine and 1.5 (95% CI, 1.17 to 2.02) occasions greater after the Pfizer/BioNTech vaccine than that of their COVID-naïve friends.
