I heard on NPR today that the Moderna vaccine is 95% effective after one dose. But of course the pharmaceutical companies want to sell more product so they are insisting two doses are needed, and the politicians who take their special interest money are falling in line.

In a local news story homeless people are now being vaccinated and this is one example of a group it will be hard to track down for second doses. One dose should be headline news. We can double the number of people we vaccinate quickly, and just in time as a worse strain than the UK one is spreading around from South Africa. But if the crisis ends soon, and things return to normal, politicians can no longer control people with fear.
