I was talking to a coworker about turning down the tetanus vax for a cut I got (mentioning chemicals, etc., as to why) and another coworker chimed in saying there are no chemicals in the vax, just the dead disease. I told him I'd gladly read anything he wanted to show me but that my research says otherwise. Then he said he's EMT trained and that's how he knows. Is that what they're teaching in health-related schooling?
