A comment on Oxford University breakthrough on global COVID-19 vaccine. Parent comment
Can you count infections as a metric of efficacy for a vaccine that's designed to stop infection?
Consider [1]:
"However, protection was 90% in an analysis of around 3,000 people on the trial who were given a half-sized first dose and a full-sized second dose."
AFAIK it's not known how many of those 3,000 in that trial were exposed to potential infection.
