Some people believe that vaccinations are completely unnecessary and offer protection against diseases that are already removed from the population, thus rendering vaccination simply a redundant money making enterprise by pharmaceutical companies. Anti-vaccine groups will often push this theory at you.
On the other hand, pro-vaccine groups will adamantly defend vaccinations and consider your choice not to vaccinate tantamount to neglect and irresponsible.
Information like this has been condensed in a book by (pro-vaccine) Dr Sears, called The Vaccine Book. It is easily available at public libraries. I got mine from the Toronto Public Library.
This book does NOT go in to the controversies surrounding vaccines. It has simply condensed already available information about vaccines (from pharmaceutical companies) in to an easy to read format for the layman.
The root cause of concerns still remain: The vaccine-autism connection has not been debunked. Parental observations continue to be adamantly ignored and rubbished.
Although I have not attributed my sons's autism to vaccines, no study has yet proved otherwise. I am still trying to figure out what happened to him. In the meantime, I continue to learn more about the immune system, environmental toxins and human behavior. I continue to use available techniques to help him which include ABA, RDI, dietary intervention and a healthier more informed lifestyle.
We do intend to vaccinate our daughter, but have decided to delay to learn more about what she will be receiving and to observe her natural development.
Then there is a whole other side to vaccines which often people do not consider. Which is, how controversial are their ingredients. Muslims will put toothpaste, cheese, lotions and other items under scrutiny for their halal nature, but has anyone ever considered what you are injecting in to your child?
Some ingredients found in some brands of vaccines contain monkey kidney cells, fetal cow blood, formaldehyde, DNA and protein fragments from human fetal cells and so on.
My advice to parents would be to try and educate yourself as much as possible. Do not go with a fad, or make rash emotional decisions. God has instructed man to use his intellect for matters of this world.
The Vaccine book is a good place to start for some mainstream information.
