Experts agree that the impact of the jab will vary regionally and among different groups
Analysts are involved in an urgent effort to gauge the impact of Britain’s mass Covid-19 vaccine campaign and to pinpoint dates when lockdown measures can be eased.
More than 3 million people – most of them elderly or vulnerable individuals or health workers – have already been given jabs. Now researchers are trying to establish when the first fruits of the mass vaccination programme may be seen as the government heads towards its target of immunising more than 13 million people by 15 February.
