Vaccine efficiency
Regarding the issue of the effectiveness of vaccines against the corona virus, the World Health Organization cites several laboratory studies that show that risk of transmission infection to a person is reduced by about half by at least one dose.
The United Nations says people have a lower risk of transmitting the disease 7 or 14 days after receiving both doses. Up to date, more than 90 studies on the effectiveness of vaccines have come from the countries that first introduced the vaccine business, Israel, the United Kingdom, and the United States.
