In response to the detection of the circulating type 2 virus in Somalia, a series of targeted campaigns using monovalent oral polio vaccine type 2 (mOPV2) are underway. The next campaign is planned for 21 August. Health workers are intending to reach 1.1 million children under the age of five living in Puntland and Somaliland with the life-saving vaccine. This campaign will be synchronized with parallel immunization activities carried out in Somali region, Ethiopia.
Preparation for the Campaign
In preparation for the August campaign, an immunization activity review workshop has been initiated in Hargeisa and Garowe to discuss the results of the last vaccination round, and the way forward to ensure better campaign quality.
A revaccination strategy has also been finalized, to help ensure that more children will receive vaccine doses.
To help reduce the number of children missed by polio vaccination teams, UNICEF has planned joint training for vaccinators and house�to-house mobilizers.
