when pfizer was given after two pfizer shots, antibody levels rose eightfold, but from a much higher initial level. moderna and other combinations also worked well. the study didn t look at omicron. it has mutations in the spike protein which may make antibodies less able to bind onto it and prevent infection, but the bigger the antibody army, the better. t cells, another part of the immune system, were also significantly boosted. these can spot and destroy infected cells. the study showed boosters worked well against beta and delta variants, so it s likely they will also protect against serious disease with omicron. all of the vaccines actually showed a good t cell response. for the antibodies, moderna and pfizer were very high. we re very hopeful that the vaccines will provide a broad protection against multiple variants although we can t say
nearly 3,000 uk volunteers got one of seven different covid vaccines as a booster shot three months after their second dose. thank you very much indeed, everybody. for those boosted with pfizer after two doses of astrazeneca, their antibody levels were 25 times higher than a control group after one month. when pfizer was given after two pfizer shots, antibody levels rose eightfold, but from a much higher initial level. moderna and other combinations also worked well. the study didn t look at omicron. it has mutations in the spike protein, which may make antibodies less able to bind onto it and prevent infection, but the bigger the antibody army, the better. t cells, another part of the immune system, were also significantly boosted. these can spot and destroy infected cells.

amid the gloom over omicron and its potential threat, some encouraging news. it was back in the summer that nearly 3,000 uk volunteers got one of seven different covid vaccines as a booster shot three months after their second dose. thank you very much indeed, everybody. for those boosted with pfizer after two doses of astrazeneca, their antibody levels were 25 times higher than a control group after one month. when pfizer was given after two pfizer shots, antibody levels rose eightfold, but from a much higher initial level. moderna and other combinations also worked well. the study didn t look at omicron. it has mutations in the spike protein, which may make antibodies less able to bind onto it and prevent infection, but the bigger the antibody army, the better. t cells, another part of the immune system, were also
