One in fifty thousand is still damn good odds.

I'm sure there will be more such cases. As other folks here are pointing out, sometimes that's just how it goes, even for somebody who "should" be in no danger. Sometimes 20-year-olds die of the flu.

But you still don't help yourself by getting into a tailspin over it. If you're sick, that just depletes your energy and makes it harder to take care of yourself so you can get better. If you're not, the same stress weakens your immune system and makes it harder to stay well.
