The second round of the national Oral Polio Vaccination (nOPV2) Campaign in all districts in Botswana is set to start from the 27th to 30th March. The campaign is targeting all children aged seven years and below, who were vaccinated in the first round, last month. The campaign also targets those who missed the first round. Vaccination will be conducted in households, health facilities, schools and other areas where children can be found.
