I don't think a summer went by, from the time I was about 6, that I didn't have at least one case of poison ivy. Once I got it in January, when I apparently wore some item of clothing which was still contaminated for the previous summer. Then, in about 1974, I received a series of 3 shots, March, April, and May. Now, at 55, I have never had even the tiniest symptom of poison ivy since that time. And, yes, I've definitely been exposed. I've never encountered another person who has had those shots and have no idea what they contained. Anyone have any information about what happened to this vaccine that completely eliminated my sensitivity? |
