The United States is facing a shortage of yellow fever vaccine that could stretch into next year, the Centers for Disease Control and Prevention warned Friday.
While measures are being taken to alleviate the impact, travelers who need to be vaccinated against the virus may have a hard time getting the injection and may have to travel within the US to do so. Where 4,000 clinics normally offer yellow fever vaccinations, merely 252 in the country will have vaccine while the shortage persists.
