Hi aaronsmummy. There are homeopathic strategies. I'm not sure what the approach is exactly but my understanding is that it has to do with supporting the immune system more generally and helping to sort out any weaknesses as part of a more holistic approach.
There may well be some more sensible people on the thread later. I know some MNers are quite knowlegable on the subject.
Meanwhile I recommend the book Mass Immunisation - A Point in Question, bu Trevor Gunn. He started life as a micro biologist and is now an esteemed homeopath. He also gives great lectures.
Good luck. A word of warning ... if you choose any path which isn't along the established medical route, you can expect people to feel free to critisise and be rude to you. Ignore them. Do what you believe to be best for you child and let the bullying wash over you.
