Danish vaccine maker Bavarian Nordic A/S is making more of a smallpox vaccine typically stockpiled in case of biological warfare, as governments seek doses that also offer protection against monkeypox amid an unusual outbreak around the world.
Monkeypox, a viral illness that is only rarely detected outside of Africa, has been reported in recent weeks in at least 17 countries including the U.S., U.K., Spain, Portugal and Australia, according to nonprofit data platform Global.health. In the U.S., a case was confirmed in Massachusetts and at least five more are suspected—one each in Florida, New York and Washington and two in Utah, state officials and the Centers for Disease Control and Prevention said Monday.
