Most parents these days have had no contact with anyone to lose a leg to polio or have a child die from Rubella. Because of this, people are less than excited to give their children these shots. If people could see what these immunizations were preventing them from, parents would not hesitate to give their babies shots. They would line up for days like they do in third world countries to get these miracle drugs. Dr. Leonard Krilov is quoted by saying, " I believe the hesitancy stems, in part, because a majority of today 's parents (and clinicians) have not had first-hand experience with many of these vaccine-preventable illnesses and do not realize the potential morbidity and even mortality from these diseases. As a result, it is easier to focus solely on safety concerns and for naysayers to perpetuate misinformation."
One controversy is what is in the shots themselves. "While the media have reported claims of a potential link between the MMR vaccine and vaccines containing mercury (thimerasol) and autism, extensive scientific reviews have not found any association," (Pantell, 2009). This is one conflict that "non-vaxers" have with immunizations. They are tearing apart the chemicals in the drug. While this is good to do and understand what you are putting in your body, they have to understand that most chemicals in these vaccines are needed to get the medicine to do its job
