Interesting line about how the effectiveness rose to 80 per cent in people given an initial half dose and then a full dose.

From what I understand, this is a field where 50 per cent effectiveness is considered good, so I'm not sure I buy that bit about 70 per cent being a "disappointment" and I don't get how thirty cases of Covid among those who were given the vaccine and 101 in those given a dummy works out at 70 per cent protection when 20,000 people were involved in the testing.
Up to 90% Bob not 80%.
