@kjoed53 I think you somehow misunderstood what I said. I said I talked to a woman who had a bad reaction to a tetanus shot and was on a ventilator. Of course she was told this by a Dr, as her condition was life threatening. I also said it was second hand, of course, but that I had heard similar stories. By the way, I have learned a lot from nurses, PA’s, Nurse Practitioners, and technicians. A lot of these people have worked in their area for a long time and are very knowledgeable and helpful. I consider them health care professionals and am always glad to hear their input and expertise. They have much to offer.
