Donald, when I first moved to Ecuador 12 years ago we, too, got the CDC-recommended vaccinations — same as those you mention here. (We did get the Hep B) I’m not sure if we really needed them (and a lot of people are vehemently against vaccinations of any kind) but for us, it’s now a done deal.
I do know from experience that if you ever travel from Ecuador or Colombia with your destination as Costa Rica you will need to have your original international health certificate at hand proving you have had the Yellow Fever vaccination. Costa Rica is the only country I’ve had this issue with – -but if you’ve had the vaccination, then you’re good to go as long as you have the proof…your card. Supposedly, Ecuador has eradicated malaria so you won’t need that. But do be careful of dengue if you go to the coast. You can’t get a vaccination for that, so wear your repellant and use mosquito nets or screens on your windows while you sleep. Take these precautions and you should be fine.
