Pfizer/BioNTech says three doses 'effective' against Omicron

Two doses of the BioNTech and Pfizer coronavirus vaccine may not be enough to protect against the Omicron variant, the companies warned Wednesday, but stressed it was "still effective" after a third jab. In preliminary results published on Wednesday, Pfizer and BioNTech said their vaccine "is still effective in preventing Covid-19, also against Omicron, if it has been administered three times".
