In people over 60, the rates of confirmed Covid-19 and severe illness were substantially lower after a booster (third) dose of the Pfizer vaccine than after two doses, new data from Israel shows. The study looked at more than 1 million people over 60 years of age who had been fully vaccinated with the Pfizer vaccine at least five months earlier. The study found that 12 days after the booster dose, the rate of infection was 11 times lower in the booster group than in the non-booster group. The rate of severe illness was almost 20 times lower in the booster group.
