Don't know about Common Cold other than the many vitamin regimens and pills/potions suppressing the symtoms, but Influenza is well covered. Countries where it's a common late autumn/winter event have extensive programs for 'temporary' inoculation for population groups that are at risk like the seniors/elderly, kidney, heart , lung and others. It does not necessarily 100% protect, but if one catches it, it often does not go beyond the experience of a good cold.

Like the AIDS virus, it continuously mutates, thus re-inoculation has to take place every November (northern hemisphere).

There is no specific DC to my knowledge that specifically covers these 2, but surely, things will come out as by-product from other life-science related DC's.

Thanks Sek, lawrence!

I didn't notice that thread before, :-). I was also going to mention SARS but I forgot to.

Another way to stop Flu from spreading: Paint it over :O MIT's anti-microbial 'paint' kills flu, bacteria
