I encountered operational challege were during SIA, specifically OBR using mOPV2 antigen. I observed that the fixed post team were given only bOPV which is the right antigen for routine while ignoring the purpose of the campaign (mOPV2 not given). They were intructed to give both mOPV2 and bOPV concurrently in other to ensure children received RI and SIA doses. When we reffered to the stakeholders it was revealed that guideline stipulated that, child should receive only mOPV2 and resheduled for bOPV next contact. i have little imformation that needs clarification from immunzation experts and/or refference materials for capacity building in support of the guideline.
1. What is the possible consequence of given mOPV2 and bOPV at same time? any scientific justification.
2. Weighing the risk of missed oppurtunities and combining both antigens at same, which one should i prioritised?
Thanks alot waiting for your input.
