Oh yeah, you will want to get flu shot just in case too.. I can say that I went to Cartagena (Colombia) after my flu vaccine has expired and I got sick with flu down there. Also, I think it is better if your family doctor prescript your medicine instead of Travel Clinic facility because if it comes from your family doctor then insurance will pay for it but if it came from travel clinic then most likely your insurance won't cover. You may need to double-check with your insurance, though. The travel clinic should be able to answer this to you, which is how I learned about it so I had my dr prescript for me the medicine. You may be correct about A & B but I got a Twinrix which would cover all three A & B for lifetime until I die. Just want to get it over with so if I decide to travel somewhere else on a whim I don't need to worry about it.
