In the global rush to approve vaccines, there is some good news on the horizon. The UK just gave emergency authorization to a COVID vaccine developed by AstraZeneca and Oxford. This vaccine has the advantage of not needing sub-zero refrigeration and is much cheaper than any other drug ($3 to $4 a dose.) This is especially important for developing countries. The new vaccine can also be stored in a regular refrigerator for 6 months.
The British health service is set to vaccinate a million people per week at makeshift sites in huge soccer stadiums and racetracks.
In China, one of their fast-tracked vaccines was shown to be 79% effective and could be rolled out to millions soon.
