re: #258 Teukka

So… I have good news and bad news… The bad news:

The good news is that I haven’t heard anything about variants of concern wrt Poliovirus, so *knocks wood* ze polio jab should still woik.

Apparently, covid is an outlier (also influenza). Most RNA viruses are stable, and no-one knows (yet?) why the rapidly mutating ones do it.

(There were three strains of polio, two now extinct.)
