I'm certain as part of the trial ALL volunteers will be tested for Covid at intervals so asymptomatic cases will be picked up.
I do think the small number of infections across the 20,000 makes it difficult to predict efficacy with any degree of accuracy.
Those with symptons didn't need hospitalisation.
I'm part of the Novavax trial.
The good thing about this vaccine is the suggestion that it might reduce passing on the virus.
Novavax told The Mail on Sunday that its vaccine 'prevented infection' between rhesus macaque monkeys in testing.

(That's not me in the picture)
I had a Covid test before we started along with a blood test.
I got a jab and the computer decided if it was live or a placebo.
I've had no side effects.
I get another jab on Day 21 and a third visit is needed on Day 35.
I then go back after 3 months, 6 months and 12 months and will have blood tests each time.
If I become eligible for an approved vaccine over the period of the trial I won't be prevented from having it.
