The first dose of the Pfizer coronavirus vaccine is 85% effective after two to four weeks after vaccination, a new study shows.

More than 9,000 health workers at Israel’s largest hospital, Sheba Medical Center in Tel Aviv, participated in the survey. 

On December 19, the hospital launched a comprehensive mass vaccination campaign. It is considered the world’s fastest vaccination campaign.

The study, published in the Lancet Medical Journal, also shows that the vaccine is 47% effective between day one and day 14. The effect increases to 85% after 15 to 28 days.

Israeli studies have previously shown that the vaccine is 95% effective one week after the second dose.

Research is still being conducted into whether fully vaccinated individuals can still infect others with the coronavirus.
