We just got back from 3 hours in the emergency room with Joel. He's fine now, his stomach pain is most likely the result of his second does of the oral typhoid vaccine he took yesterday. About 10 percent of people will get this reaction...we are glad it wasn't appendicitis! So the next step will be to have him get the injection version of the vaccine.
Chile is quite safe as far as this sort of thing goes. The only inoculations recommended (as of this writing) is to get hep A, typhoid, and of course a flu shot. Since hep A is now standard for kids, and we get our flu shots every year, this was a piece of cake-at least until today!
