If you plan to travel to Democratic Republic of Congo then it is wise to check you are up to date on the following vaccinations:

Yellow Fever -required for all travelers. Without a certificate you can be refused entry into the country
Hepatitus A & B
Tetanus – diptheria
MMR (measles, mumps and Rubella)

Rabies-for travelers spending a lot of time outdoors, or at high risk for animal bites, or involved in any activities that may bring them into direct contact with bats.

Malaria is prevalent across Democratic Republic of Congo so a prophylaxis is recommended for all travelers. However Rumangabo is located 1600m above sea level so the incident of mosquitoes is much lower.
