Ouch! That's Humiliating.

90% immunity is what you achieve by just doing nothing.

So for any vaccine developer 90% is considered the minimum grade needed for a pass.

70% is the threshold below which herd immunity cannot be achieved.

So I hope this is highly effective for the over 65's and other vulnerable groups. They're the only ones who are going to benefit.

I wonder how Britain is going to dump the other, roughly, 38 million doeses that it's over-ordered.
