Now that the U.S. Department of Health and Human Services (HHS) has declared monkeypox a public health emergency, nearly two weeks after a similar declaration from the World Health Organization, the way is cleared for a coordinated response and emergency use authorizations to address supply challenges that could limit the availability of currently approved vaccines. It also has several companies ready to leap into the fray if their preclinical studies show a path to approval. HHS said it just shipped more than 602,000 doses of the Jynneos vaccine to states and jurisdictions, an increase of 266,000 in the past week.
