Statistics re antibodies

[Frostyhighlights]

I have read that some people test positive for Covid on an antigen test but then 3 weeks later an antibody test gives a negative result. I believe there is some idea that some people have a T cell lymphocyte 'response' to the virus and do not produce antibodies.

Does anyone know if there is real data available on this?? What percentage of people who have definitely had a positive test then go on to show no antibodies?

I read this today, dont know how accurate. Suggests only 10% of people produce antibodies
