Not exactly to the point, but close: do get yourself the basic shots (hepatitis, tetanus, etc.) and while at it you might have this documented too - this is called the yellow book (a proof and record
of your vaccinations) - this is not required but there are health
issues, esp. in the poorer places (Cuba, Haiti
, Dominicana, Venezuela). Also, to lesser extent - in the ex-English colonies. No issues in the ex-French/Dutch places though, except for Dengue, but there is no vaccine for this one.
