Due dosi del vaccino anti-Covid di Pfizer offrono circa il 70% di protezione contro la malattia grave da variante Omicron. E' quanto emerge dai risultati di uno studio pubblicato in Sudafrica.
OMS, omicron si diffonde
Telegiornale 04.12.2021, 13:30
Lo studio si basa sui risultati di 78'000 test PCR effettuati in Sudafrica tra il 15 novembre e il 7 dicembre ed è stato condotto dalla principale compagnia di assicurazioni sanitarie private del Sudafrica, Discovery, insieme al South African Medical Research Council.
I primi indicatori suggeriscono che Omicron potrebbe essere più trasmissibile, ma finora dati promettenti hanno suggerito che i vaccini offrono ancora protezione contro questa variante. L'ultima ricerca in Sud Africa ha suggerito che due dosi del vaccino Pfizer/BioNTech offrono ancora protezione contro la malattia grave.
Secondo Pfizer/BioNTech, due dosi del vaccino offrivano una protezione del 93% contro le varianti precedenti.
