Single dose of Oxford vaccine can cut COVID-19 transmission risk by 67 percent, study indicates

The Oxford-AstraZeneca vaccine significantly reduces virus transmission and is highly protective after a single dose, according to an Oxford University study, which the British government said Wednesday vindicated its inoculation strategy. "It slows transmission by around two-thirds, so it categorically supports the strategy that we're undertaking," Hancock said.

Although the European Medicines Agency recommended it for adults of all ages last week, several countries have advised against administering the AstraZeneca jab to older people.
