* Decision Table: Birth dose administration as part of "bivalent oral polio vaccine (bOPV) plus inactivated polio vaccine (IPV)" schedule (in countries that are poliomyelitis (polio)-endemic countries or at high risk of importation and subsequent spread of polio that follow the combined bOPV–IPV schedule)
* Trigger: IMMZ.D2 Determine required vaccination(s) if any
