I can't yet recommend it because it was only lent to me today, but you could try:

"The Vaccine Book: Making the Right Decision for Your Child" by Dr Robert W. Sears.

It doesn't appear to be pro or anti-vaccination, but it gives details about the disease, the ingredients in the vaccine, the possible side-effects, and some reasons why people choose to vaccinate or not to vaccinate for that particular disease. It's by an American author but I think the information should still be relevant for Australia.

It's published by Little, Brown and Company in the USA. The edition that was given to me was published in October 2007.

I can give you a better review of it once I've read it! You can also check out his website - google Robert Sears or Dr Sears.

ETA: He also gives a long list of other resources that you might like to try.
