The manufacturer of yellow fever vaccine (YF-Vax), Sanofi Pasteur (Swiftwater, PA), has informed CDC that the supply of YF-Vax (the only yellow fever vaccine available in the United States) is currently limited. As a result, the manufacturer has placed limits on orders of the single-dose and 5-dose vials of YF-Vax. These ordering limits are expected to be in place until April 2014.
