An Imperial College London survey showed 87.9% of people over the age of 80 tested positive for antibodies after two doses of the Pfizer-BioNTech vaccine, rising to 95.5% for those under the age of 60 and 100% in those aged under 30.
Antibody levels are only one part of the immunity picture, with vaccines also shown to generate strong T-cell protection. The research found 34.7% of those 80 years or older generated antibody responses from one dose of Pfizer vaccine, but Britain’s Joint Committee on Vaccination and Immunisation has previously found high protection from the Pfizer vaccine after one dose, even when antibody levels are lower.
