SO THE World Health Organization has decided swine flu is a full-on pandemic (鈥淪wine flu vacccine gets go ahead鈥�). How worried should we be? After all, most cases so far are mild. The trouble is that pandemic flu is, by definition, a novel influenza virus sweeping the world, so billions are at risk because they have no immunity to it. That is not good news. We know H1N1 can kill, and, unlike ordinary flu, it strikes the young and healthy. Flu pandemics also come in waves, and the next one could be much worse, raising the grim spectre of a repeat of the 1918 pandemic when tens of millions of lives were lost. At least the WHO鈥檚 declaration means companies can now turn their attention to churning out pandemic vaccine as fast as they can. That鈥檚 the best we can do. What happens next is up to the virus.
