No antigens? Even better, you may have T-cells that remember Corona

'It looks increasingly like T cells might be a secret source of immunity to Covid-19.'

The BBC reports that some people may be immune to Covid-19 even if they get back a negative antigen test.
According to their article from July 19, 2020:

”Several studies have shown that people infected with Covid-19 tend to have T cells that can target the virus, regardless of whether they have experienced symptoms. So far, so normal. But scientists have also recently discovered that some people can test negative for antibodies against Covid-19 and positive for T cells that can identify the virus. This has led to suspicions that some level of immunity against the disease might be twice as common as was previously thought.
