I skimmed through this entire thread last night, emphasize 'skimmed', as it did get difficult, at least, at times. Aunt Sophie's blog isn't going to be all that reliable a resource, for sure.
Enough!
Over decades, and some foreign travel, we've had many different vaccines, a couple as volunteers in vaccine trials, and we were delighted to get all of them. This drama over a very well tested product seems like a lot of whining to me, from folks who don't remember smallpox or polio, who didn't have measles or chicken pox, or shingles, never mind typhoid, typhus, or cholera. And who have safe products against rabies, as so many in the world don't.
Rant over.
