Australia’s Chief Medical Officer, Professor Paul Kelly, spruiking AstraZeneca vaccine:

“In terms of preventing death, it works 100 per cent of the time. In terms of preventing severe illness, it works 100 per cent of the time.” (paywall)

This statement was based on one small trial in which only 12% were over 55. The control group had one death and two severe cases, whereas the vaccine group had zero deaths and zero severe cases.

Tom Kompas, University of Melbourne professor of economics and biosecurity:

“I would say there was no basis for making that claim. Relying on that sample size is just absurd. You wouldn’t make any statements about that.”
