In Tsholotsho district, Matebeleland North Province, Junior Ndlovu stands in line with other parents at Gandisa Business Centre, her two children by her side. They are waiting to be vaccinated against polio.
“I understand the importance of immunization and believe it’s crucial for children to receive these vaccines,” says Junior, reflecting the sentiment of many mothers who brought their children for the campaign featuring the novel oral polio vaccine type 2 (nOPV2).
At this single location, over 102 children received the vaccine, contributing to the district’s overall reach of 96,403 children. These children are amongst a total of 4,633,015 vaccinated across Zimbabwe during the four-day mass campaign that concluded on 23 February 2024.
The Ministry of Health and Child Care (MOHCC), in collaboration with UNICEF, the World Health Organization (WHO), Bill and Melinda Gates Foundation (BMGF), US Centre for Disease Control (USCDC) and other partners, launched this nationwide campaign using the nOPV2 vaccine following the confirmation of circulating poliovirus type 2 (cVDPV2) in Zimbabwe.
Targeting all children under 10 years old, this nationwide campaign aimed to swiftly stop the spread of the Polio virus and prevent future outbreaks. The campaign followed the detection of a Polio outbreak through sewage samples collected in Harare during routine environmental surveillance. Additionally, intensified disease surveillance by the MoHCC identified one human case of polio in Mashonaland West.
“While this campaign marks a significant milestone, our fight against polio is not over. We must remain vigilant and continue to prioritize routine childhood immunizations to ensure lasting protection,” said Minister of Health and Child Care Dr Douglas Mombeshora.
Vaccination teams adopted a two-pronged approach, deploying mobile units to deliver doses directly to homes and stationing personnel at health facilities to ensure widespread coverage. The campaign also incorporated the Open Data Kit (ODK) to facilitate real-time data sharing and improve campaign efficiency.
Zimbabwe became the first country to utilize the nOPV2 vaccine after its prequalification by WHO in January this year, three years after it received its Emergency Use Listing (EUL). By early January, 950 million doses had been delivered worldwide, with Nigeria administering nearly half a billion doses. The nOPV2 vaccine helps to protect children from polio while lowering the risk of vaccine-derived outbreaks. In the African region, Malawi, Mozambique, Nigeria, and Ethiopia, are some of the countries that have successfully used the vaccine.
