On Monday, BioNTech and the American pharmaceutical group Pfizer revealed the first data results from their Phase 3 clinical study for the vaccine candidate BNT162b2.
Phase 3 of the trial involved 43,538 participants. These participants received two doses of either the immunisation or a placebo, with 90 percent protected from the virus within 28 days of having their injections.
So that means, according to the results, the risk of contracting Covid-19 was more than 90 percent lower for study participants who received the vaccine than those who didn't.
The firms say there have been no serious side-effects.
The companies, who teamed up to develop the vaccine together, have not provided information on how long the protection could last.
The two partner firms plan to apply for emergency approval for the vaccine in the US later this month. If sufficient data on the safety of the vaccine is available, which is expected in the third week of November, the application should be filed soon after.
