Hancock: Oxford vaccine may reduce transmission of Covid by two-thirds
Guardian, 03 Feb 2021
The UK health secretary, Matt Hancock, has welcomed a new study that suggests one dose of the Oxford/AstraZeneca vaccine may reduce transmission of coronavirus by two-thirds. Hancock said the results of the trial backed up Britain's strategy to delay the administering of the second dose of the vaccine by 12 weeks.
Hancock added: 'We may well need boosters that have a slightly adjusted vaccine as well in the same way that we do for flu each year.'
Single dose of AstraZeneca vaccine could cut transmission by 67%
