Under which AO are non-WHO prequalified rabies vaccines permitted in case of a shortage?

The correct choice signifies that AO No. 2018-0013 specifically addresses issues related to vaccine shortages, including rabies vaccines. This Administrative Order lays out the guidelines and allowable provisions for using non-WHO prequalified rabies vaccines during periods of shortage. It illustrates the health authority's readiness to adapt protocols in response to public health emergencies, ensuring that adequate vaccine supply remains accessible.

This order allows for flexibility in vaccine sourcing without compromising safety or efficacy, crucial during public health crises when the urgency for vaccinations is heightened. The other options, while they may pertain to various health regulations, do not specifically focus on protocols for addressing shortages of rabies vaccines. Thus, the emphasis in AO No. 2018-0013 makes it the correct reference for this specific context.
