I did see a couple of reactions [to the influenza vaccine], and they were so dramatic that everyone knew it was from the vaccine. And at that point we just thought.. well, this just happens sometimes. We considered it no different from any other drug that you can react to, so that was how it was back when I was naive. But the other question is, it was so dramatic what I saw with the other two… one was a measles vaccine and the other was a chickenpox vaccine, both in adults. Both caused fulminant, horrible inflammatory kidney failure and put these people on dialysis. But that was so obvious that nobody had any real doubts as to what happened. But there’s all kinds of issues in between. Some reactions don’t happen in the first 24 hours, it can actually take weeks to set up an autoimmune reaction to a vaccine.
