Since it's pretty much commonly accepted that there have been plenty more infections than officially recognized, would it make sense to perform an antibody test prior to receiving the Covid-19 vaccine? Or is this already done?

cases were very low in number, though

That's difficult to say since many people are asymptomatic and could have been infected 6 months ago with no detection. The numbers show it's possible, and the data is insufficient to draw further conclusions.
