Polio’s back in Papua New Guinea for the first time since 2018—this time, it’s the vaccine-derived kind. WHO found the virus in two healthy kids, which is a big deal because it means the virus is circulating again. Only 44% of kids there get all their polio shots, so health teams are scrambling to boost vaccinations and stop the spread. Wild polio’s mostly gone, but these outbreaks remind us it’s not over yet! #PolioOutbreak #PapuaNewGuinea #WHO #VaccinesWork #PublicHealth #Health
