Maybe we got placebo ...

"Flu season expected to get worse - Vaccine doesn't match most circulating viruses, health officials say" - MSNBC, 2/15/08:

The flu shot is a good match for only about 40 percent of this year's flu viruses.

The biggest surprise has been how poorly the vaccine has performed.

Kenny's the worst, with headache, weakness and chills.

I'm weak and queasy but benefitting from daily naps. Jeff, who didn't get the shot, is perfectly fine. Chris and Ella had their own gunky eye thing last week. Tim seems fine.

Maybe the symptoms are mild because me and the kids got the vaccine.
