That's how British Health Secretary Matt Hancock described the UK's vaccination effort on Twitter Sunday after more than 20 million people across the UK received a covid 19 vaccine.

Britain has rolled out Europe's fastest covid 19 vaccination program, raising the prospect of a lifting of its current lockdown restrictions between now and the end of June.

The country also reported a further 6000 and 35 cases within the previous 24 hours and 144 more deaths within 28 days of a positive test.

The latest figures meant cases over the past seven days were down 21.2% compared with the previous seven day period, and deaths were down 33.5%.
