Going into the EMT field and I dont want to get the Hep vac any suggestions or advice

I am currently taking an EMT course and will eventually go on to Paramedic school. I DO NOT want to take ANY vaccines, as I know the potential for illnesses. I especially do not want to get the HEP B vaccine series. ANY suggestions as to avoid this? I know I don't have to get it and of course I must be VERY careful about pricks and sticks, etc. But I don't want to be pressured by those individuals etc. I have worked so hard to get my immune system healthy, that I dont' want to break it down with chemicals and have to work hard to get it back up. I have read the forums and they scare me to death. What if that is me? HELP, anyone! Thanks flurry1 Tweet
