Complete coronavirus vaccination with Pfizer and Moderna reduces the risk of 94%, όπως προκύπτει από τη μεγαλύτερη μελέτη που έγινε μέχρι σήμερα από το Κέντρο Ελέγχου και Πρόληψης Νοσημάτων (CDC) σε πραγματικά περιστατικά και όχι κλινικές δοκιμές.
None of the participants had been vaccinated with Jonhson & Johnson.
The study was designed only to test whether vaccines prevent symptomatic disease. However the fact that only a small percentage found positive was fully vaccinated, indicates that the vaccine may prevent not only disease but also infection and transmission.
In a statement accompanying the study the CDC director, Rochelle Walensky, emphasizes that “this report provided the most exciting information to date. That is, the coronavirus vaccine had the expected effect on the world. ". "This study, added to the many previous studies, was crucial for the CDC as its recommendations for those who have been fully vaccinated against coronavirus change ", he added.
This study was one of the pieces of evidence used by the CDC to guide fully vaccinated Americans.. More specifically, the CDC wanted to say that those who had made their plans can be safely found outdoors or indoors without masks.. Of course there are some exceptions which include airplanes and buses.
The study was conducted in a network with more than 500.000 sanitary. However the data were limited to 1.843 who probably got coronavirus during their work. There were between them 623 individuals who tested positive and 1.220 found negative. In fact, only the 40 from the 623 had been vaccinated with both doses. Δηλαδή μόλις το 3% of those tested positive were fully vaccinated, compared to 15% of individuals who had been found negative.
This suggests (but does not prove) ότι τα πλήρως εμβολιασμένα άτομα διατρέχουν πέντε φορές λιγότερους κινδύνους να νοσήσουν από κορωνοϊό και μεταφράζεται σε αποτελεσματικότητα εμβολίου που φτάνει το 96%. However, The study did not include people who tested positive for coronavirus and were asymptomatic.. Therefore the study cannot prove that the vaccine prevents infection.
Alongside 64 people who tested positive for the Pfizer or Moderna vaccine and 241 which were found negative. Αυτό σημαίνει ότι ακόμη και μία μόνο δόση ήταν 82% αποτελεσματική κατά της πρόληψης των συμπτωματικών. In other words, the risk of coronavirus disease has been reduced by 94% for more than 120 millions of people and 155 millions run through 82% λιγότερο κίνδυνο να αρρωστήσουν. Μαζί με άλλες μελέτες, η νέα έρευνα ήταν αρκετή για να πείσει το CDC ότι οι πλήρως εμβολιασμένοι μπορούν να κινούνται χωρίς μάσκα διατρέχοντας τον ελάχιστο κίνδυνο να αρρωστήσουν από τον κορωνοϊό.
