Nhivan-
Dr. Sears just wrote a book called "The Vaccine Book". I just finished reading it after picking it up from the library. I highly recommend it, mainly because it discusses the concerns about autism, mercury, etc., but he also explain the pros, the disease history, how severe of a disease it is, and he also proposes an alternative vaccination schedule.
Delaying some of the vaccines makes sense. We delayed 2 ourselves. On the other hand, some of the diseases are most severe when the child is an infant or toddler.
A lot of the stuff about DTP, mercury, etc. that I read on the "anti-vax" websites were outdated, according to what I read in this book. It was just released at the end of 2007, and it is very up to date.
BTW - they don't give the DTP vaccine anymore. They switched it to DTaP, so the side-effects and issues were addressed with a new vaccine.
** Re: the vaccine schedule is the way it always was.
NOT true. Some vaccines, like the varicella, was not even common or "recommended" until 2006!! Mainly due to the burden on parents for staying home with the child, economic loss, etc. The condensed, multi-vax doses were done to make it "convenient" for the parents, also to increase vaccination rates by making it more convenient.
Mercury was essentially banned, so that is less of an issue. Aluminum is still widely used. There is some legacy with mercury you have to watch out for.
I would pick up Dr. Sears book. It is very informative and up to date without a "YOU MUST VACCINATE" or a "VACCINATIONS ARE ALL BALONEY" sort of slant. After doing some independent reading (and I do have a science/engineering background and 4 years of graduate work), I'm leary of the vaccine schedule but NOT vaccines.
Re: Your kid cannot enter school without vaxes-
This is NOT true. California has a law in place where the parent can sign an affidavit saying they elected to not have their children have one, some, or all the vaxes for philosophical reasons. http://www.nvic.org/state-site/California.htm
Many states have religious exemptions, some have the same exemption California has. This only applies to public schools however. Private schools can abide by a different policy. Universities tend to be even more strict, since they are already battling STDs.
