Importantly, the risk of covid-19 in general, including asymptomatic infection, in which a person has the virus but doesn’t feel sick, was also reduced by 75% in that same period, based on regular PCR testing.

Based on data analyzed by the Israeli Health Ministry, Reuters reported last Thursday, the risk of infection was reduced by 89% in people who received two doses of the Pfizer/BioNTech vaccine.

Compared to their unvaccinated colleagues, the workers were 89% less likely to test positive for covid-19 after they received both doses.
