UK approves second Covid-19 vaccine
The UK has approved a second vaccine to prevent Covid-19 paving the way for a stepped up campaign to immunise the population just as hospitals across the country face a sharp rise in admissions from the pandemic. The vaccine, AZD1222, was developed by Oxford University and AstraZeneca Plc and received an emergency authorisation on 30 December – a little more than four weeks after a vaccine from Pfizer Inc and BioNTech was given clearance.
