For me 30% is not half (empty or full)30%.
30% is the average; which 'average' they are referring to, I am not sure of. However: It is a bit like, half full or half empty, kind kind of thing. Your glass appears to always be; half empty.
I have had the 1st jab of the OAZ vaccine. So now I am more protected, than I was. Still feel drained and tired. The latest strain, (no longer the Indian strain) is not the only one, out there, waiting for me to catch it. I understand, that there are 1.000s of strains out there, no matter, because I am a little more protected, that I was before, from all of them.
That said. Just to quench your half empty cause. Two of the people who died in the Bolton area hospitals last week, had had both their jabs. No one said, which jabs and it doesn't really matter, they are obviously fell into the percentage of, 'the failure to protect.'
In addition, researchers from the Institut Pasteur say that AZ works very little or even not at all against Indian and South African variants.
Very little or not at all does not represent 30% but 10% or 0% for me.
