I'm not sure what you really want to know....Are you considering this? Do you have specific questions about where to find details on the alternative schedule? Where to find a pediatrician who will support whatever decision you make? What factors to take into account when deciding? Questions about school? I have heard secondhand that the local Kaiser is now splitting out vaccines and it seems almost a standard now. (I don't belong but women in another chat mentioned this)
Toni had some great input and questions to consider. I don't envy any of us this decision. It will be a great day if this issue could be "de politicized" (okay, I think I made up a word but I think you'll get it) and answers sought for the sole purpose of helping future generations. I'm actually on a different track as far as vaccines are concerned. Fortunately there isn't autism in our family, even extended. However, my Father, Sister, Brother and I have all had severe allergic reactions to vaccines. My Father was left deaf in one ear. The most recent was my sister, she has a heart condition and was told to get a flu shot so she did. That almost did her in and she is still having health problems which may be related to the vaccine or just worsening of her condition. Probably for most other people this would have been the best course of action but there is something obviously going on in our genetics regarding vaccines and I really haven't experienced support, answers or validation of our concern regarding this from the medical community.
Anyway, about the alternative schedule....from what I know it originated from Dr. Sears and is detailed in his Vaccine Book. You may find more information at His website http://www.askdrsears.com/
or be able to get his book from the library. If this is something you're concerned with you may just want to get your own personal copy.
As far as school in CA, any state accredited school (this includes private school and preschools) is required to use the same form/procedure, there is a place on the form to fill out for exemption. When you travel as a child or an adult for that matter you may need to get immuniations depending on where you travel. My Sister In Law went to India for work and had to have vaccinations, one for Malaria. My stepson went to Indonesia 3 years ago with the Peace Core and wasn't vaccinated then or ever. So it's not like your child would NEVER be able to travel, they just might have to have specific vaccinations before and you'd need to plan as you can't do it the day before you leave ;-).
Anyway, there are dire statistics regarding the diseases vaccines protect against. You can do a little research and find them. The statistics about Autism and related conditions are also staggering. Again, I don't envy any of us having to make this decision.
