There may be no immunity against Covid-19, new Wuhan study suggests

Lack of antibodies in the bloodstream does not equate to lack of immunity.

- There could be antibodies at the mucosal level (IgA)

- There could be cellular responses (T cells) that aren't detected

- There could be immunological memory at play after antibodies aren't detectable anymore

A critique of the work, a little heavy-handed:

I read that too before [1].

On contradiction [2], from today. "Despite that, Gates said recent evidence points to the antibody response being "very strong," which suggests about a year of immunity to anyone who gets the disease."

It gets incredibly difficult to make opinion on all this. In the meantime, people are dying. That's verifiable.
