After seeing @charles shepherd thread, I was wondering what the thoughts were of everyone here regarding the thread title? Maybe they have some experiences that they wouldn't mind sharing! Just a quick background as to why I have given this thought! Within my job their is a risk of getting Hep B because of the children we work with. The school pay for all those it concerns to have the vaccine, which is opptional. I was due to have this last March but because I was off sick due to this illness I wasnt there to have it when the nurse came to the school. My boss asked me to check to see if I can have it because they are worried that it will make me sicker. Of course when I asked they said it will be fine. After searching online, I decided not to have it as I didn't think it was worth the risk. Also there is the question about flu vaccine, I have had it in the past but it made me ill, so I decline now when asked. Feel free to discuss amongst yourselves, I just thought it might be an interesting topic to discuss in length. It doesnt have to just be about the Hep B Vaccine but any.
