Summary
Brief summary
To better understand why wild poliovirus persists in Gadap, and other such areas in Pakistan, it is important to know the proportion and age of children that lack mucosal immunity despite repeated polio vaccination campaigns. These are the children who do not necessarily become paralyzed when infected with poliovirus (PV) but who harbour the PV and further transmit it to others; resulting in continued low level PV circulation that has been observed in Gadap and other areas. It is known that mucosal immunity rapidly wanes however it is less well understood to what extend this immunity wanes in populations repeatedly vaccinated with OPV. Currently, IPV is added to the routine immunization program in Pakistan and therefore it is possible that there is a growing cohort of children whose humoral immunity is present but mucosal is absent. We intend to quantify this proportion and determine whether there are possible programmatic strategies to target these children.
