Dopo l'EMA anche gli USA. Il vaccino contro il Covid di Oxford-AstraZeneca è sicuro e altamente efficace. Lo dicono i risultati della tanto attesa sperimentazione effettuata negli Stati Uniti, secondo quanto riporta la BBC.
EMA: "vaccino AstraZeneca sicuro ed efficace"
Telegiornale 18.03.2021, 21:00
Il vaccino è risultato efficace al 79% nell'arresto della malattia da Covid sintomatica e al 100% nel prevenire che le persone si ammalassero gravemente. Non sono stati constatati problemi di sicurezza per quanto riguarda i coaguli di sangue.
Alla sperimentazione hanno partecipato più di 32'000 volontari, principalmente in America, ma anche in Cile e Perù.
