While there is trial data to support the gap for the AstraZeneca vaccine, there is none for the Pfizer vaccine, which was given as a second dose at three weeks. More than 17.5 million have received one vaccine dose so far  more than a third of the U.K.s adult population. Broader testing in the overall population showed that the Pfizer vaccine was 57% effective in preventing symptomatic illness in people over 80 three to four weeks after the first dose. The first thing we can say based on these data, is that when you are offered the second dose, please also take that because its very important. Both vaccines are being given as single doses until up to 12 weeks.
some 12826 people got one dose of an anti-age vaccine.
