For example, if they were to go to South Africa, they would need more immunizations, like yellow fever, hepatitis A and B, tetanus, Cholera, and Ebola. If they were to go to Central or South America, on top of all the shots mentioned for South Africa, they would also require immunizations for cerebrospinal meningitis, measles, mumps, and chicken pox. However, if they were to go to more developed areas like Europe or North America, they would require fewer immunizations, but mumps, measles and rubella were definitely necessary.
