With regard to testing and the Oxford study cited above, what is tested when you have the current test for Coronavirus? Is is just whether you currently have the virus or does it also pick up antibodies showing you have previously had it?
If it's the latter then the Oxford study can presumably be refuted or supported very quickly from existing data. Even if it's a completely different test then has no govt or health service already done these? All sound like half a tale to me.
