According to the Center for Disease Control (CDC), there are no required vaccinations to travel to Panama. Recommended vaccinations and medications include:
Transmission of hepatitis A virus can occur through direct person-to-person contact; through exposure to contaminated water, ice, or shellfish harvested in contaminated water; or from fruits, vegetables, or other foods that are eaten uncooked and that were contaminated during harvesting or subsequent handling.
If you might be exposed to blood or body fluids (for example, health-care workers), have sexual contact with the local population, or be exposed through medical treatment, a Hepatitis B vaccination is recommended. Hepatitis B vaccine is now recommended for all infants and for children ages 11-12 years who did not receive the series as infants.
If you might have extensive unprotected outdoor exposure in rural areas, such as might occur during camping, hiking, or bicycling, or engaging in certain occupational activities, a rabies vaccination is recommended.
Typhoid fever can be contracted through contaminated drinking water or food, or by eating food or drinking beverages that have been handled by a person who is infected. Large outbreaks are most often related to fecal contamination of water supplies or foods sold by street vendors.
Recommended for travelers to endemic areas in Panama.
As needed, booster doses for tetanus-diphtheria.
