I would WILDLY speculate that it would be best to get this new flu NOW than to get it a year from now.

WHY?

The Reason being is that you would acquire some resistence to this new type A H1N1 flu so that when it does   [ and it will ]   MUTATE into a a new form of type A flu ONE YEAR from today, you will have somthing akin to a vaccine already in your system.
For example Carol might already have gained a resistence to a type A flu, having had 'a' flu last month.

Please do not go to Mexico City or lick city bus seats upon this speculation. ":^/
