Well, we go fairly frequently to SE Asia ... but have never been vaccinated for trips. However, as I said, we're both adults. Though, I don't think this makes a big difference.
For what it's worth, we plan to continue our travel lifestyle with a child, and won't be vaccinating him/her either. We only know one another couple who doesn't vaccinate and they live on a sailboat, traveling everywhere with their 3 year old.
Otherwise, everyone else we know thinks we're nuts.

I just don't see the logic in "you must get vaccinated before travel" thing. It seems, to me, that if diseases were SO widespread, then we'd have an epidemic of them everywhere - not just certain countries. Just because, we live in a very global world, where air travel with lots of people traveling from lots of different places happens daily. Not only people - but things are shipped all around the world. I'm sure the products aren't going through a sanitization process anywhere.
Yet, with all that travel ... there really aren't that many epidemics in most countries. And they don't spreak in the places where one breaks out. A lot of the disease in undeveloped countries can be tracked straight down to lack of nutrition, bad water, inefficient immune system, no hygienic conditions, etc.
So, I just don't see the logic in the whole vaccination thing.
Though, obviously, I understand there are differing views on this.

The only times we've gotten sick is when we were so hot and parched, and just could no longer care about the ice the street vendor was serving in the drinks. Though, we certainly cared that evening, with only one bathroom between us two, lol.
Gitti - I totally agree. It's incredibly freeing! Plus, stress weakens the immune system, making one more predispositioned to catch something.
Anyway, have fun on your trip. Fiji is so incredible! 4 months of travel sounds like so much fun. Lucky.
