LONDON - Scientists have said that AstraZeneca may offer longer-lasting immunity than other vaccines, prompting speculation that the jab has helped Britain avoid the latest Covid wave in Europe.
The chief executive of the pharma giant said the decision to give the Oxford vaccine to older people in Britain could be one of the reasons the UK was not seeing not “so many hospitalisations relative to Europe” despite a high number of cases.
Several European countries restricted the AstraZeneca vaccine to under-65s in the early stages of their rollouts.
