Prior covid? Unless it's a severe case, one-dose mRNA vaccine adds considerable protection and nothing added by 2nd dose. This is now concordant w/ >20 studieshttps://t.co/8Qpuw193zk @acsnano pic.twitter.com/TJNbl8HPy9

Relacionados: Case series: 7 cases of myocarditis following mRNA-based COVID-19 vaccination. E Case series: clinical and cardiac magnetic resonance imaging findings of 4 cases of myocarditis following mRNA-based COVID-19 vaccination. E Case series: symptomatic acute myocarditis in 7 adolescents following mRNA COVID-19 vaccination. E CDC says heart inflammation cases were higher than expected in 16- to 24-year-olds after second Covid vaccine shot, but still rare. E Israel reports link between rare cases of heart inflammation and COVID-19 vaccination in young men. E CDC is investigating several reports that teenagers and young adults may have developed myocarditis after receiving mRNA vaccines. Most cases were mild, more often in males than females, more often following dose 2 than dose 1, and typically, within 4 days after vaccination.
