Pfizer and BioNTech says a third dose of their Covid-19 vaccine provides a similar level of neutralising antibodies to Omicron as is observed after two doses for other variants. – EPA pic, December 8, 2021.

THE Pfizer-BioNTech Covid-19 vaccine is “still effective” against the Omicron variant after three doses, the companies said in a statement today.

A laboratory study found that the vaccine “is still effective in preventing Covid-19, also against Omicron, if it has been administered three times”, but warned that “Omicron is probably not sufficiently neutralised after two doses”.
