mpox Vaccine EUAs

On November 28, 2022, the World Health Organization announced, and the U.S. government supported, renaming monkeypox disease to mpox. In response to this action by the WHO, federal public health agencies will adopt the mpox name in correspondence with the medical community and American public from this point forward.

Effective August 9, 2022, pursuant to section 564 of the FD&C Act, the HHS Secretary declared:

  • There is a public health emergency related to monkeypox, or significant potential for a public health emergency, that affects, or has the significant potential to affect, national security or the health and security of United States citizens living abroad that involves monkeypox virus; and  
  • On the basis of this determination, circumstances exist justifying the authorization of emergency use of vaccines.

Vaccine EUAs subsequently issued by FDA are listed in the table below.

PREP Act declaration: Effective September 28, 2022, the HHS Secretary amended the declaration first issued on October 10, 2008, and amended and republished effective January 1, 2016 for smallpox countermeasures and countermeasures against other orthopoxviruses pursuant to section 319F-3 of the Public Health Service Act to emphasize that the declaration applies to monkeypox virus, to expand the categories of providers authorized to administer vaccines and therapeutics against smallpox (variola virus), monkeypox virus, and other orthopoxviruses in a declared emergency, and to extend the duration of the declaration. About PREP Act declarations

On October 20, 2022, FDA also published lists of certain laboratories that have notified FDA of their laboratory developed monkeypox diagnostic test (LDT), modification to an FDA-cleared or EUA-authorized monkeypox diagnostic test, or laboratory developed monkeypox serology test, as described in Sections IV.A.2, IV.A.3, and IV.C, respectively, of the Policy for Monkeypox Tests to Address the Public Health Emergency. While FDA has not reviewed the laboratory’s validation of the listed tests and has not issued EUAs for these tests, we are providing this information to promote transparency.
