Well the latest tech report is not good news. Schools clearly source of major spread .
Emerging evidence that Delta is more severe as well.
Will thread later.
But can we finally learn that waiting for firm evidence to act is waiting too long?
One jab of AstraZeneca vaccine protects only 33% against Delta. Two jabs may protect 60%, but the 95% confidence interval goes as low as 33% as well.
