Hi, my husband, little boy and I are thinking about taking an extended trip to Equador, Colombia, and Peru. Possibly do some volunteer work, get to know the localities. My question is, will we be required to get a yellow fever vaccine to travel between these countries? According to the cdc website only part of these 3 countries are at risk for yellow fever. Will we be required to get vaccinated only if traveling from one of these areas to another but not if traveling to another part of these countries? Cdc also mentions the possibility of getting a medical waiver and being quarantined when traveling from one area to another. (We may have reason to get a medical waiver; my husband because he is 60, myself because I am breastfeeding, our son because he has an egg sensitivity. Besides, we are very skeptical of modern medicine and pharmaceutical products, particularly when its mandated.) Any idea what this quarantine is; temporary imprisonment or something more palatable? Any information you can give me would be appreciated as well as advice on how to do better searches on the computer; I'm stumped.
