Travellers to an increasing number of areas in South America and Africa are being advised to obtain vaccination against yellow fever.
US travellers are being recommended to plan ahead as the vaccine is only available at a limited number of clinics in the US. The only US-licensed yellow fever vaccine (YF-Vax) is currently out of stock but the manufacturer has made an alternate yellow fever vaccine, Stamaril, which is available at select clinics.
The US Centers of Disease Control and Prevention (CDC) has posted a Level 2 Travel Alert for yellow fever in Brazil. Since early 2018, a number of unvaccinated US travellers to Brazil have contracted the disease, and several have died. Vaccination is now recommended for more areas of Brazil than before, including Ilha Grande and the cities of Rio and São Paulo, which are popular destinations.
CDC said that people who have never been vaccinated should not travel to areas in Brazil where vaccination is recommended and that would-be travellers should talk to their doctor to make sure they are prepared.
