[pct-l] Giardia

[Shauna]

One thing about Giardia is that you do develop a bit of an immunity to it
once you have caught it.  They have even come out with a shot to prevent
animals from ever getting it.

Which to me isn't Giardia, because it's always connected with water sources. And as far as I know, none of the hikers that had to get off, either completely or just for a few weeks, never were diagnosed definitively with Giardia. Whatever.
