FDA’s Role  

The U.S. Food and Drug Administration plays a critical role in protecting the U.S. from chemical, biological, radiological, nuclear (CBRN) attacks, and emerging infectious disease threats.

The FDA's roles in monkeypox preparedness and response during this public health emergency include:

Vaccines

The FDA approved JYNNEOS Vaccine in 2019, for the prevention of smallpox and monkeypox disease in adults 18 years of age and older determined to be at high risk for smallpox or monkeypox infection.

  • This is the only currently FDA-approved vaccine for the prevention of monkeypox disease. 
  • The vaccine does not contain the viruses that cause smallpox or monkeypox. 
  • Given the emerging public health need, the FDA and government partners worked to accelerate submission of information needed to make additional U.S. doses of JYNNEOS available much more quickly than scheduled.  
  • The vaccine is part of the Strategic National Stockpile, overseen by the Department of Health and Human Services’ Assistant Secretary for Preparedness and Response, which helps ensure that the vaccine is accessible in the U.S. if needed.

Therapeutics  

Currently, there are no FDA-approved treatments for monkeypox; however, TPOXX (tecovirimat), an antiviral medication, is being made available through the CDC under an FDA authority called Expanded Access, or “compassionate use.”

As background, in 2018, the FDA approved TPOXX for treatment of smallpox in adults and children. Because smallpox has been eradicated globally, TPOXX was approved under the FDA’s “Animal Rule” regulations, as it was neither ethical nor feasible to test the efficacy of the drug in humans. TPOXX was approved for treatment of smallpox based on efficacy data obtained from animal studies, specifically non-human primates infected with monkeypox virus and rabbits infected with rabbitpox virus. Such studies were relevant since the viruses that cause smallpox, monkeypox, and rabbitpox are in the same family of viruses called “orthopoxviruses.” Safety data was obtained in healthy human volunteers without a smallpox or monkeypox infection.

Unlike smallpox, monkeypox was endemic in other parts of the world (e.g., the Democratic Republic of the Congo) at the time of TPOXX’s initial approval. Consequently, it remained both ethical and feasible to conduct clinical trials in humans to study TPOXX for the treatment of monkeypox disease. Therefore, TPOXX for the treatment of monkeypox disease was not eligible for approval under the pathway described in the FDA’s Animal Rule regulations. 

The CDC holds an Expanded Access Investigational New Drug protocol (EA-IND) that allows for the use of TPOXX for treatment of orthopoxvirus infections other than variola (which is the virus that causes smallpox), including monkeypox, in adults and children of all ages. The EA-IND provides an umbrella regulatory coverage, so clinicians and facilities do not need to request and obtain their own INDs. The FDA worked closely with the CDC to streamline the protocol to reduce data collection and reporting requirements. The revised protocol is now available for use.

Importantly, safety and efficacy of TPOXX to treat monkeypox in humans has not been established. Conducting randomized, controlled trials to assess TPOXX’s safety and efficacy in humans with monkeypox infections is essential. We don’t currently know if TPOXX will be beneficial, harmful, or have no effect in treating patients with monkeypox, since drugs that are effective in animal studies are not always effective in humans.

Fraud and Misinformation 

Unfortunately, during emergency situations, fraudulent products claiming to prevent, treat or cure conditions associated with the emergency almost always appear for sale. The FDA monitors for fraudulent products and false product claims related to emerging infectious disease threats and takes appropriate action to protect consumers.

You can report a fraudulent monkeypox product to the FDA. The page includes options for phone and online reporting in English or en Español.

Moreover, the FDA has taken significant steps to combat misinformation about FDA-regulated products being communicated online, in the news, and by high-profile public officials, celebrities, and other outlets. We continue to look for opportunities to combat misinformation head-on in ways easy for consumers to understand and communicate the potential for real harm.
