I find this thread very interesting for personal reasons, and it has taught me something that I was unaware of until now. I made the decision to receive the hep B series when I started to nursing school to protect myself, and I received my last hep B shot of the series in the beginning of April this year. At the end of April, several of my joints became inflamed, swollen, painful, and warm to the touch. I was miserable. My doctor ran tests, and then referred me to a rheumatologist. I have since been diagnosed with lupus. I am not saying that the vaccination has caused the development of lupus, but I do find it very interesting considering the timing of my vaccinations and onset of symptoms. Also, many of the sites that I just looked into have either listed lupus as a side effect of the vaccination, or stated that there is a strong correlation between the vaccination and lupus. It is definitely something that I will be looking into further.
