HARARE, Zimbabwe (AP) — More than 33 million children in several southern African countries have been vaccinated against polio, part of ongoing efforts to eradicate the infectious paralytic disease that has been largely contained in much of the world, the World Health Organization announced on Friday. About 80 million drops of the inoculation have been placed in the mouths of children across Malawi, Mozambique, Zambia, Tanzania and Zimbabwe since the launch of an emergency response in March last year, WHO said in a statement. Vaccinations will continue in southern Africa “so that every child receives the protection they need,” WHO’s Africa director Matshidiso Moeti said
