I think it's all a personal choice. I'm very very anti-vaccine and I don't want to shove it down anyones throat. But really that link said some of it. Only if you're going out of your resort and eating or drinking unsafe food then I don't think you really need any vaccines. I'm more taking vitamin B12, Vitamin E, etc. I think if you're in your resort the chances of getting some life threatening are pretty low. I would definitely read up on both sides of getting a vaccine and look at the risks of the vaccine and the risk of the disease. And weigh your pros and cons. If you want help on any of the vaccines you're thinking of getting, please PM me.
