Response to the Mpox Outbreak


Strategic National Stockpile (SNS)


Mpox illnesses, including severe infections, continue to occur across the United States. The Strategic National Stockpile remains focused on rapidly deploying mpox vaccines and therapeutics to the most affected communities and mitigating the spread of the disease while maintaining a focus on fair and equitable distribution of the product.
