If you look at India's cases over the last 4 months, it appears the delta variant burns high but also burns out quickly.
They have not gotten anywhere near our vaccine rate and cases are falling rapidly.
Delta is infecting younger people because of the vaccines making it harder to infect the more vulnerable.
It has to infect younger people and work harder to do so, it it dies out.
Delta took 2 months to reach the peak in India. We're already a few weeks into rising cases.
So if you let it run now, in the summer, it will be burning itself out by the time winter hits.
People are outside more in summer which naturally reduces transmission rates. Couple that with reducing transmission due to vaccines and it may burn out faster because there is a rapidly decreasing pool of people without antibodies.
The flu vaccine will be a complete guess this year as flu rates have been so low in the last year due to covid.
The NHS has to get on with elective surgery and treatments. Or more people will die from preventable injuries/diseases.
It is now or never, and the economy can't stay in shutdown much longer.
The UK is leading the way in terms of life after vaccines; but India has already proven that cases won't just rise forever.
We can't do zero covid. It's not possible.
It also doesn't appear to have triggered a new mutation in India - or at least not one worth worrying about.
