Emergent250GAITHERSBURG, Md., November 7, 2023 – Emergent (NYSE: EBS) has recently submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking approval for the expansion of the indication for ACAM2000®, Smallpox (Vaccinia) Vaccine, Live to include immunization against mpox virus. The sBLA includes data from a well-controlled animal study in which ACAM2000® vaccine has been shown to be effective in protecting against mpox virus exposure.

“Community transmission of mpox continues to be a public health challenge in the U.S.,” said Paul Williams, SVP and Products Business Head, Emergent BioSolutions. “Our sBLA submission for ACAM2000® reflects Emergent’s commitment to expanding our product capabilities and continuously support the U.S. government as we address emerging infectious diseases and strengthen future preparedness.”

Mpox, formerly called monkeypox, is a rare disease caused by infection with the mpox virus. Mpox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Mpox symptoms are similar to smallpox symptoms, but milder, and mpox is rarely fatal.1 Since the start of last year, there have been more than 31,000 mpox cases in the U.S. and 55 deaths, according to the CDC, with more than 91,000 cases and 166 confirmed deaths globally.

ACAM2000® is currently licensed for active immunization against smallpox disease for persons determined to be at high risk for smallpox infection. 

ACAM2000®, (Smallpox (Vaccinia) Vaccine, Live) 

ACAM2000® is the primary smallpox vaccine designated for use in a bioterrorism emergency, with doses having been supplied to the U.S. Strategic National Stockpile. ACAM2000® is also licensed in Australia and Singapore and is currently stockpiled both in the U.S. and internationally.

ACAM2000® is indicated for active immunization against smallpox disease for persons determined to be at high risk for smallpox infection.

The labeling for ACAM2000® contains a contraindication for individuals with severe immunodeficiency. Severe localized or systemic infection with vaccinia (progressive vaccinia) may occur in persons with weakened immune systems. Individuals with severe immunodeficiency who are not expected to benefit from the vaccine should not receive ACAM2000®. The risk for experiencing severe vaccination complications must be weighed against the risk for experiencing a potentially fatal smallpox infection.

Additionally, there are warnings and precautions for myocarditis, pericarditis, encephalitis, encephalomyelitis, encephalopathy, generalized vaccinia, severe vaccinial skin infections, erythema multiforme major (including Stevens-Johnson Syndrome), eczema vaccinatum resulting in permanent sequelae or death, ocular complications; blindness and fetal death have occurred following either primary vaccination or revaccination with live vaccinia virus smallpox vaccines. These risks are increased in certain individuals and may result in severe disability, permanent neurological sequalae and/or death.
