Emergent BioSolutions Inc. (NYSE:EBS) today announced that Singapore's Health Sciences Authority (HSA) has approved an expanded indication for ACAM2000® (Smallpox and Mpox (Vaccinia) Vaccine, Live) to include prevention of mpox disease in adults determined to be at high risk for mpox infection.

The expanded indication in Singapore is supported by existing human safety data and data from a well-controlled animal study in which ACAM2000® vaccine was shown to be effective in protecting against mpox virus exposure. This regulatory milestone expands the authorized use of ACAM2000® in Singapore to support public health preparedness and response efforts.
