I find travel docs tend to over kill and/or dont really understand the region (Central America anyway).
Look to WHO/CDC for fact based recommendations.
For example, CDC/WHO only recommend Yellow Fever vaccination if travelling to remote
areas E of the Panama Canal
Here in Central America
the biggest concern is the hemoragic strain of Dengue...for which there is no vaccine. Regular Dengue wont kill u, just make you feel like dying.
Many think of Malaria as one disease but its not...there are many strains. By far (something like 95%) the most common strain in Central America is very mild and very treatable. Whereas some of the preventatives are hard on your body and have side effects. They are also not 100% effective. Ive known several visitors who took anti malarial meds and still got malaria.
Also if you do contract
a tropical disease, for your own good get treated in the region where you got it and the docs know the diesease. Ive know several who went back to the USA and had very bad experiences with docs who just dont know tropical diseases...one young girl who was damn near killed by the Hospital trying to treat a simple Bot Fly infestation (look that one up...it may keep you awake at night!) 😆
