If 8 out if 10 people have covid antibodies...

...as has been reported today, how can there be any justification in delaying the roadmap beyond 21 June?

Honestly not being goady. Genuinely wondering if the aim is for 100% to have antibodies? Also, that number is surely increasing daily anyway, so by the 21st many more will have antibodies.

I'd have thought that people having antibodies is the main aim - what other requirements are there for full reopening to go ahead? Are there any?

8/10 is great. But it’s still 2/10 who are vulnerable and that’s enough to allow significant outbreaks to happen. More people infected means more viral replication and more chance for mutations where the vaccine may be less effective. And that would be really bad news. I think it’s actually a good argument to delay because we are getting closer and closer to the point where we could have say 95% protected and then that risk is significantly lower.

But the 2 out of 10 who don't have antibodies aren't vulnerable, surely? CV people are pretty much all fully vaccinated now.

That’s true - those 2/10 are v unlikely to be vulnerable and to get severe Covid (though may still get debilitating long Covid). But more infections means more viral replication means more opportunities for a mutation which could be vaccine resistant to develop - and that could be a significant risk for those who are more vulnerable whether or not they’re vaccinated.

@chinateapot you can stilll catch it once vaccinated so can still generate more variants
