We have a 17 year old daughter and a 12 year old son...
We have a 17 year old daughter and a 12 year old son, who have neither received any vaccinations during their lifetimes. My daughter remains very healthy and is a competitive figure skater. My son had some heath issues when he was a baby. My son was diagnosed with PPD NOS (pervasive developmental delay not otherwise specified), which has now been classified as autism spectrum disorder. We went through extensive testing, trial and error and dietary changes to try and determine what was the cause for his issues. With all test results coming back as 'normal', at 11 months of age we put him into speech, occupational and physical therapies. When he was 2 1/2 years old, a special geneticist finally uncovered a b12 deficiency (in both he and I), which had been masked in other testing. We administered the b12 and continued his therapy. At four years of age, my son was released from all therapy and considered 'typical' in development for his age. He is now 12 years old and functions typically in school, excelling in most subjects. He also exhibits typical social skills for a 12 year old boy (okay - so many jokes could be made here). According to the standards set by the medical establishment, my son was 'cured' of autism. Though I don't believe he was ever truly on 'the spectrum'. We have friends from that time in our lives whose children still struggle with delays in one area or another. After speaking with many mothers who discovered symptoms in their children after vaccinations, I do believe that had my son, in his precarious state, been immunized, he would not be considered 'typical' today.
Neither of my children has ever had an ear infection, allergies or asthma. We have many friends whose children suffer with asthma and allergies, diabetes and even crohn's disease, all of whom were vaccinated. In my small case study (circle of friends), those few children who were not vaccinated tend to be much healthier than those who were.
