Why the study?
Does the cessation of the type 2 oral polio vaccine lead to the expected decay in Sabin-like type 2 detection rates?
Does the cessation of the type 2 oral polio vaccine lead to the expected decay in Sabin-like type 2 detection rates?
Modeling of SL2 detection rates post-OPV2 cessation established benchmarks for expected decay and identified anomalous detections requiring enhanced monitoring for cVDPV2 outbreaks.
No takes yet. Share an insight, caveat, or question.
May raise cVDPV2 outbreak risk during OPV2 transition; leaves open optimal SL2 surveillance strategies.
Kroiss et al. (2017) studied this question.
