I've always wondered that actually, why there's an immunisation payment when it's free...
Guess it's to encourage people to immunise, because they don't realise it's available to everyone?

ANYWAY! I haven't looked too much into alternatives yet Alexis, but definitely made my decision not to immunise with the intention to breastfeed to at least 12 months (Riv weaned just before then cos I was pregnant). I think that gives them a great head start in terms of immunity.
It also helped that we weren't in any high risk groups in regards to things like HepB.

For us, it's also a decision that's ongoing, we haven't said NEVER immunise, it's just always, 'not now' or 'not yet'. Who knows, perhaps once Riv is walking with bare feet outside we'll consider tetanus. We didn't consider it necessary at birth, with him often having a cold anyway, for his immune system to have to cope with something else that we didn't feel he needed at that stage.
It's not a decision we made once and then that's it, we often review it, because life changes and if I ever consider that immunisation is a risk worth taking, then we'll take it. But that's not been the case thus far.

Anyway, all the best with your decision, it can be confusing to find balanced information (as opposed to either propaganda or scare tactics!) and I'm very interested to watch what you come up with in regards to alternatives!
