The Oxford-AstraZeneca vaccine is so far said to be 70 per cent effective. The Oxford vaccine was only 62 per cent effective if administered in two equal doses. Professor Andrew Pollard, director of the Oxford Vaccine Group, said it was an "intriguing" finding. It also is thought to travel better and can be stored is standard fridges unlike the Pfizer vaccine which needs to be kept at -70C. Additionally, the Oxford vaccine already has a production line ready to start cranking up with AstraZeneca estimating it could have 200 million doses ready in just weeks.
