There are two strategies for decreasing the risk of yellow fever: vaccination and limiting mosquito exposure.

The yellow fever vaccine is given in one dose and is 95 percent effective within one week, and will remain effective for 10 years. At-risk persons should receive a booster every 10. While the vaccine is considered safe, there are certain populations that cannot be vaccinated, including infants, pregnant women, persons with a weak immune system, and persons with an egg allergy.

Limiting mosquito bites is likewise an important preventive strategy. Use effective insect repellents such as those with DEET and completely cover the body with clothing while outdoors. Protect living spaces with screens and netting. Areas of standing water attract mosquitoes and therefore should be avoided or eliminated.
