The World Health Organization (WHO) is launching a global strategy to halt the transmission of mpox, formerly called monkeypox. The plan, announced on Aug. 26, will entail a “strategic vaccination” campaign. The U.N. health agency, which declared a public health emergency of international concern two weeks ago, said that the plan will last six months—September 2024 to February 2025—and will receive $135 million in funding.

“Strategic vaccination” efforts will target people at the highest risk such as “close contacts of recent cases and healthcare workers, to interrupt transmission chains,” the agency said.

The WHO plan will focus on “implementing comprehensive surveillance, prevention, readiness, and response strategies; advancing research and equitable access to medical countermeasures like diagnostic tests and vaccines; minimizing animal-to-human transmission; and empowering communities to actively participate in outbreak prevention and control,” according to a statement.
