I think you are being overly specific. When the average person says "I try to avoid chemicals" you know good and well what they are talking about. That issue is your perceived issue. The fact is chemicals can most certainly be bad -- but you need to teach them that the positives gained from receiving a vaccine greatly outweigh the risks in the minuscule amount of volatile chemicals (mainly, mercury) you receive. Ionizing Radiation is most certainly not good for you, and exposes you to risk for cell damage, but people understand the tradeoff when they go to the hospital to get an MRI to find out how best to repair their knee, or PET Scan to find out what the best course of treatment for their cancer is. You get into these problems when you turn your nose up at people, act smugly, and say "chemicals are fine!" Rather a better strategy to combat those anti-vaxxers is to be up front "Yes there is mercury in here, and yes too much is bad for you. But your body has a liver, kidneys, and lymphatic system that does a tremendous job of cleansing toxins from your system, and the benefits you receive from this vaccine far outweigh the cons from a little bit of mercury."
