Yellow Fever Vaccine Access

YF-VAX®, (Yellow Fever Vaccine), will be unavailable from mid-2017 to mid-2018, due to delays in the production process. Sanofi Pasteur has worked with the FDA to make another yellow fever vaccine available in the US through an Expanded Access Investigational New Drug Application (IND). Manufactured by Sanofi Pasteur in France, this vaccine, STAMARIL® (Yellow Fever Vaccine [Live]), is registered and distributed in over 70 countries. However, it is considered investigational in the US, as it is not a US-licensed product.

The Expanded Access Program has requirements similar to a clinical trial; thus Sanofi Pasteur can support only a limited number of sites. Working closely with the CDC, geographically distributed sites throughout the US were identified for inclusion in the program so patients can have continued access to yellow fever vaccine.

Once YF-VAX vaccine is no longer available, health care providers and patients will be able to find locations that can administer STAMARIL vaccine by visiting the CDC web page at They may also visit for information about which countries require yellow fever vaccination for entry and for which countries the CDC recommends yellow fever vaccination.
