Impact of #vaccination on new #SARS-CoV-2 infections in the United Kingdom

Étude communautaire évaluant les vaccins Astra-Zeneca et Pfizer : efficacité élevée sans différence entre les 2 #vaccins ; surtout efficaces contre les formes symptomatiques et celles à charge virale élevée ; intervalle de confiance trop large pour savoir si les #variants non alpha sont aussi sensibles que le variant alpha.
Conséquence de ce qui est mis en gras :
Overall, approximately one-fifth of infections with Ct < 30 were in individuals not reporting symptoms during their episode. These infections could be particularly relevant for #transmission as these individuals may not be aware of their infection status despite having a relatively high viral load. Maintaining measures such as social distancing may therefore still be needed to control the virus spread until enough of the population is vaccinated.
