Coronavirus immunity could only last a few months after a study revealed that the number of people with the protective antibodies to the disease had fallen over the summer.
Research by Imperial College London estimated just 4.4% of adults had some form of immunity against Covid-19 in September, when cases began to increase again.
This is compared with 6% found to have antibodies between June 20 and July 13, and 4.8% between July 31 and August 31.
It means more than 95% of England’s population is unlikely to have the antibodies needed to protect them from coronavirus.
It comes as discussions over a "Tier 4" are said to be happening amid concerns the current tier system in England is not going far enough to bring the R rate down. Read more here.

Warrington council leader defends Tier 3 deal
Warrington’s Labour council leader Russ Bowden defended the deal done with the Government as the authority entered Tier 3 coronavirus restrictions.
He admitted that “we went in with a larger ask than what we got from Government” but denied it had been a “case of rolling over”.
Warrington council will receive a financial support package of £1.68 million to help contact-tracing and enforcement, as well as £4.2 million in business support from the Government.
Mr Bowden told ITV’s Good Morning Britain: “Ultimately we had to make a call whether or not to accept that, that’s what a negotiation is about.
“We have got a good deal for the people of Warrington, we have got promises for further funding that will come out in due course.
“This was the right decision to make. Sometimes they are tough ones, you don’t always get what you ask for, but I can absolutely assure the people of Warrington that we have got them a good deal.”
