People over 40 in the UK will be offered their first coronavirus vaccination by Easter on April 4 as a boost in supplies will allow rapid expansion of the inoculation programme, The Telegraph has reported, citing a senior government source.

Vaccine stocks are expected to more than double, allowing the National Health Service (NHS) to offer a million doses a day in coming weeks, the newspaper said. People over the age of 50 are expected to receive an invitation for a vaccine dose over the next week, around three weeks ahead of the government's target, according to the report.
