The UK hit a major vaccine milestone on Wednesday, with Health Secretary Matt Hancock announcing more than 25 million people have now received their first Covid vaccine dose. More than half of the adult population have now been vaccinated against coronavirus, an incredible feat accomplished just 100 days after Margaret Keenan became the first person vaccinated against Covid-19 in the UK. Alongside this remarkable news, the Prime Minister also had some vaccine news of his own when he appeared in the House of Commons for Prime Minister’s Questions today.
