Levels of protective antibodies in people wane "quite rapidly" after coronavirus infection, say researchers.
Antibodies are a key part of our immune defences and stop the virus from getting inside the body's cells.
The Imperial College London team found the number of people testing positive for antibodies has fallen by 26% between June and September.
They say immunity appears to be fading and there is a risk of catching the virus multiple times.
More than 350,000 people in England have taken an antibody test as part of the REACT-2 study so far.
In the first round of testing, at the end of June and the beginning of July, about 60 in 1,000 people had detectable antibodies.
But in the latest set of tests, in September, only 44 per 1,000 people were positive.
It suggests the number of people with antibodies fell by more than a quarter between summer and autumn.

So much for herd immunity. I will like to expound on another Trump accomplishment. The US has a higher per capita death rate than Sweden who is using the herd immunity approach. Now that really takes some talent from the POTUS.

Then it is very clear that the system of quarantine and lock down long term won't work. I suspect if people catch it a second time it will be more like a cold but we'll see
