A response with monovalent oral polio vaccine type 2 (mOPV2) in the Quetta and neighbouring districts is now planned, in line with internationally-agreed protocols.  
To ensure high quality, preparations are focusing on allocating adequate resources to the highest-risk areas; tailoring operational plans to identified reasons for missed children; validating vaccination teams’ microplans, vaccinator selection, training and supervision; and enhancing local engagement with communities through community leaders. In order to jointly address transmission across the common reservoir, close coordination is ongoing with Afghanistan teams at all levels.
