Stockpile levels for pediatric vaccines: how much is enough?

Area of Science:

• Public Health
• Epidemiology
• Supply Chain Management

Background:

• Vaccine production interruptions have led to supply shortages, impacting timely childhood immunizations in the US.
• These shortages risk epidemic outbreaks of preventable childhood diseases.
• The Centers for Disease Control and Prevention (CDC) utilizes national pediatric vaccine stockpiles to manage these disruptions.

Purpose of the Study:

• To analyze the adequacy of CDC-proposed pediatric vaccine stockpile levels.
• To determine appropriate stockpile levels for achieving vaccination coverage targets.
• To calculate funding requirements for optimal pediatric vaccine stockpiles.

Main Methods:

• A stochastic inventory model was employed to analyze vaccine stockpile levels.
• The model considered historical vaccine production interruption durations (averaging over 1 year).
• Analysis focused on ensuring sufficient supply to meet vaccination schedules.

Main Results:

• The study assesses the sufficiency of current CDC-proposed stockpile levels.
• It provides data-driven recommendations for optimal pediatric vaccine stockpile quantities.
• Estimated funding needs for establishing adequate stockpiles are reported.

Conclusions:

• Optimized pediatric vaccine stockpile levels are crucial for maintaining vaccination schedules during production interruptions.
• The findings offer insights for public health policy regarding vaccine supply chain resilience.
• Adequate funding is essential to support robust national vaccine stockpiles.
