Antibodies

I have just taken a look at a paper on its way to peer review which suggests that the antibodies resulting from SARS-CoV-2 infections do not stick around for as long as one might have hoped. Just one bit of evidence in what appears to be a rather complicated picture.

No doubt when this paper emerges from peer review, something will have been done about the rather ineffective colour coding of Figure 2, particularly in the rather busy left hand panel. More or less illegible on this laptop, even when zoomed. Fortunately, the underlying data is provided in Table 2, at the end of the paper, from which I learn that London is at the top and the Southwest is at the bottom.
