Omicron variant, Pfizer: “Dose booster vaccine guarantees high protection”

Three doses of Pfizer vaccine ensure high protection against the Omicron variant. Albert Bourla, CEO of Pfizer, announces the “good news” based on the results of the studies. “To be clear with the listeners – he tells Nbcnews – three doses of the vaccine are as effective against Omicron as the two doses were effective against the other variants. The booster dose greatly increases the effectiveness of the vaccine”. Read also The information provided by Pfizer comes just hours after the first data from a study conducted in South Africa. The Pfizer vaccine, with the two standard doses, may be less effective against the Omicron variant. This indication is linked to the first data of a small study conducted in South Africa by the Africa Health Research Institute. The researchers, based on data published online and not yet peer-reviewed, have highlighted a “clear reduction” in the protection offered by the vaccine – with the ordinary cycle – against the variant.
