A large study of UK healthcare workers finds that immunity after coronavirus infection lasts for months, but those with antibodies may still be able to carry and spread the virus upon reexposure.
Fewer than 1 in 10 dialysis patients sampled had antibodies against the novel coronavirus as of July, indicating that the greater population is far from levels required to achieve herd immunity.
Preprints from the first round of seroprevalence studies indicate that many more people have been infected with the virus than previously reported. Some of these studies also have serious design flaws.
