Could the Oxford Vaccine Change the Course of the Pandemic?

The University of Oxford has released new data on its Covid-19 vaccine which suggests the jab may reduce transmission by 67%. This means the jab, developed with drugs firm AstraZeneca, could have a greater impact on the pandemic, as each person who is vaccinated will indirectly protect other people as well. The study, which has not yet been peer-reviewed, has also shown that the vaccine offers protection of 76% up to 12 weeks after a single dose. This supports the UK’s government strategy of delaying the second shot to protect more people quickly with a first dose. The UK has given a first vaccine jab to 9.6 million people so far.
