My boys and I made a trip to the Health Department this morning and got our H1N1 Flu Mist. I know that the vaccine isn’t completely effective (or at least as effective as it’s going to be) for a couple weeks, but I’m curious if anyone knows the rate of effectiveness in that two week period. Meaning, does it offer some protection today and then a little more tomorrow, etc.? Or does it take awhile to kick in at all?
