I'll never be ill again?

In contrast to my healthy start to the year...I got a call up from the Dr's to tell me I am in the 'at risk group'. Of what you might ask? Flu apprantly. Because I am asthmatic I qualify for the vaccination jag. I'll have anything that's for free so I am now immune to 3 types of flu. The problem is, there are more than 3 types out there and you can bet your grannies earings that one of them will find me before the winter is out.
