Some countries require that you get the vaccine or a booster dose in order to travel there. If you’ll be travelling, check the CDC’s travel page.Ask your doctor whether it’s safe for you to get the vaccine if you’re pregnant or breastfeeding, over 60 years old, or have HIV without symptoms.Do NOT get the vaccine if you’re allergic to any part of it, have symptomatic HIV or other immune system disorders, have cancer, or are taking immunosuppressant drugs or recently had a transplant.

Don’t put repellent over cuts or wounds, or into your eyes. Wash off repellent with soapy water when you go indoors.It’s safe to use insect repellent on children. However, do not use oil of lemon eucalyptus on children under 3 years old.
 Wear long-sleeved shirts, pants, and socks when outdoors. Spray insect repellent that contains permethrin over your clothes to deter mosquitoes from biting through the fabric. You can also purchase clothing that is pretreated with permethrin – a repellent you can use over clothes but not directly on your skin., Though many mosquitoes are most active from dusk to dawn, one type of mosquito that transmits yellow fever is also active during the day.
