By the way - it doesn't have to be a black or white argument either - many parents choose to delay vaccination until the child's immune system is more developed, and many pick and choose the vaccines which are associated with less risk (for example, many avoid the 12 month MMR combined vaccine). Some even choose to do homeopathic vaccination, with a few conventional vaccines later on.
Try not to stress about the decision - simply empower yourself with knowledge, and know that IT IS a parents right (and arguably their responsibility!) to know each and every ingredient which may be potentially injected into their child- what these ingredients are, where they come from, how they are cultured, what their potential short-term, long term and accumulative effects are in the human body.

Best of luck with your decision. XX
