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

Efeitos da vacinação na transmissão domiciliar do SARS-CoV-2 na Inglaterra – “A probabilidade de transmissão domiciliar foi de aproximadamente 40 a 50% menor em familiares de pacientes-índice vacinados 21 dias ou mais antes do teste positivo do que os familiares de pacientes-índice não vacinados.”
24 Jun, 2021 | 11:04hRelacionados: Study in England showed one dose of COVID-19 vaccine can cut household transmission by up to half – This protection is on top of the reduced risk of a vaccinated person developing symptomatic infection, which is around 60 to 65% after the first dose E Covid-19 vaccination prevents transmission from vaccinated to unvaccinated household members.

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.

In case you're assuming the price of Covid vaxes is going to go down, this group is here with bad news from the trajectory of flu vaxes: the more there are, the higher the prices go. Just great. 😧 From @jasonlschwartz & co https://t.co/66QHwazmES
