Before traveling to Nairobi, certain vaccinations are recommended to protect against diseases endemic to the region. The Centers for Disease Control and Prevention (CDC) recommends vaccinations against hepatitis A and B, typhoid, yellow fever and rabies. Routine vaccinations such as measles, mumps, rubella, polio and influenza should also be refreshed. Visitors to Nairobi should contact their physician at least four to six weeks prior to their trip to receive the necessary vaccinations and medical advice.
