The Pfizer vaccine produces an “off the scale” immune response that is likely to protect against the Brazilian variant of Covid-19, researchers say.
The biggest study on antibody and cellular immune factors to date suggests people are likely to be protected against the Wuhan, Kent and Brazilian types of coronavirus following two doses of the vaccine.
The research, led by the University of Birmingham and including Public Health England’s Porton Down laboratory, found 98 per cent of people aged 80 or over who had two doses of the Pfizer jab had a strong antibody immune response.
