Notice that this is for common coronaviruses, and doesn't mention SARS or MERS much: IIRC, the former elicited an IgG response years after exposure in an experiment. As far as I can tell, this preprint does not cite that work.
- arcticbull 6y agoIndeed -- studies of SARS have something different to say. Here's one study that shows duration of antibody response to SARS is at least 3 years [1]. Here's a study that shows T cell response for at least 6 years [2]. MERS had a much, much higher fatality rate (~35%) and infected a small handful of people (~2500) so it's harder to get meaningful data.

And second, those old T cells offer protection against the new coronavirus. https://www.telegraph.co.uk/health-fitness/body/no-antibodies-could-still-have-had-covid-fighting-t-cells/ https://www.telegraph.co.uk/health-fitness/body/no-antibodie...
