Real-world data from Israel suggests that COVID-19 vaccines will prevent transmission of the coronavirus, in addition to protecting against symptomatic disease.
The lack of clear data on transmission has meant that even people who are vaccinated must be careful around unvaccinated people, particularly those at risk for severe COVID-19 infections.
The preliminary information from Israel, where more than half the adults have been vaccinated, most with the Pfizer-BioNTech vaccine, showed those who received the vaccine did not develop symptoms or transmit the disease. It looks like 90% reduction in asymptomatic transmission. So that s really good, said Dr. Peter Hotez, dean of the National School of Tropical Medicine, at Baylor College of Medicine in Houston.
