From a segmentation of the infections that did occur, it appears that the immunity increases as the days go by. Among the 254 people who contracted the virus, 76 of them were infected after seven days, 44 on the eight day, and 24 on the ninth day. Between day 22 and 24 – when the test period ended – no one was infected.
According to the studies conducted by Pfizer, the vaccine had an efficacy of about 95%, which is considered very high.
