LONDON: The British government announced Sunday that it aims to give every adult in the country a first dose of coronavirus vaccine by July 31, a month earlier than its previous target.

The new target also aims for everyone over 50 or with an underlying health condition to get a vaccine shot by April 15, rather than the previous target of May 1, AP news writes.

The makers of the two vaccines that Britain is using, Pfizer and AstraZeneca, have both experienced supply problems in Europe. But UK Health Secretary Matt Hancock, who announced the new targets, said “we now think that we have the supplies” to speed up the vaccination campaign.

The early success of Britain’s vaccination campaign is welcome good news for a country that has had more than 120,000 coronavirus deaths, the highest toll in Europe. More than 17.2 million people, almost a third of the country’s adults, have been given the first of two doses of vaccine since inoculations began on Dec. 8.
