S.W.
I am coming from an educated point of view. I have a BS in Nursing, and a MS in Midwifery. I have read lots of information both for and against vaccines. I initially decided on delayed vaccines. My first child had an MMR at a little over a year, and a second one at age 3. We also started the DPT series at around 18 months, but she threw up violently for the next 24 hours. I didn't get her the second one in the series. She has not had any other vaccines.
The more I read on the topic, the more I decided not to do them at all. I have two other children, ages 4 and 19 months who have not had any vaccines. My oldest is the only one who has ever had antibiotics (once for strep throat at age 6). My children are very healthy and appear to have strong immune systems. I believe it is partly because we did not vaccinate.
People are exposed to germs all the time. The reason we sometimes get sick and other times we don't dpends on the amount of bacterial exposure and how well our body is able to present an immune response. Vaccines bypass many of the normal routes of exposure and our immune systems are not able to work and repond normally. Immune systems need practice, to develop memory cells. This is much more effective at future prevention than a vaccine.
Vaccines are also not risk free. Most side effects are mild, but in rare cases can be life threatening. I am not sure about the link to autism because there have been studies showing a connection and some which don't. It is likely that if a child already has the gene for autism, the vaccine can trigger it. My reasons for not vaccinating do not have much to do with fear of the side effects, but more to do with what I stated above.
In Ohio, you only need to have a personal reason not to vaccinate. To get into a public school, you simply have to write a letter stating you have chosen not to vaccinate for personal reasons and turn it in with the medical forms.
I also want to add that whatever you choose, it is always important to keep your child healthy in order to maximize the strength of their immune system. Make sure to feed your child healthy foods (organic when possible), ensure adequate rest, enough time for fresh air and play, decrease overall stress, and promote healthy habits such as handwashing.
