Absolutely Ax, I got all of my recommendations from an established travel clinic in a major Montreal hospital, regarding recommended shots, their evaluation of malaria risk as per their guidelines for a given area at given month of the year.
I personally had no need for worrying about mosquito born diseases, but I wasn't traveling down the coastal areas.
I have no idea what professional recommendations he has had, if any, so just wanted to start the conversation. (Albeit, leaving in less than a week probably doesn't really leave time to get an appt at a proper travel clinic)
I do know friends and family who have gotten dengue fever, malaria and chekenguya (gotta find out how to spell that properly) , but one in Africa, two others in the Carribbean. Not gulf of Mexico coast, but still wanted to address it to hopefully initiate some looking into things if not done already.
