...but I'd take this with a grain of salt. I grew up hearing about this stuff 20 years ago - my father worked with Mark von Itzstein in the development of Zanamivir
in the 80s. I heard the statement "Cure For the Common Cold" so many times since then that I'm dubious now. Note that the wiki article above notes "According to the Centers for Disease Control and Prevention (CDC), no flu, seasonal or pandemic, has shown any signs of resistance to zanamivir." so presumably, it's already the case that we have a "Cure For the Common Cold". Hell, as a young teenager I was proud that my father was involved in that exercise.
Until, of course, I saw my father interviewed with tENTATIVELY, a cONVENIENCE
and Etta Cetera
where he noted "of course, now that the cold is cured, it can no longer be used as an excuse for that age-old Australian work shirker, the sickie". That was when the full reality of my father's complicity in teh capitalist sytem struck (and horrified) me.
