How can I find out what innoculations I need for travel?

I will be going to El Slavador and Costa Rica next month. How do I see what shots or meds I may need?

You can check the Costa Rica embassy webpage here and the El Salvador embassy webpage here (the website for the El Salvador embassy to the US would not load).

I didn’t see anything requiring innoculations on either site.
