Innovative webinar-based training to support evidence-to-recommendation decision-making by national immunization...

Area of Science:

• Public Health
• Vaccinology
• Health Policy

Background:

• The Global Vaccine Action Plan and Immunization Agenda 2030 have increased the need for National Immunization Technical Advisory Groups (NITAGs) skilled in evidence-informed decision-making.
• Developing evidence-based recommendations for vaccine transitions, such as from pentavalent to hexavalent vaccines, requires innovative and flexible training approaches.

Purpose of the Study:

• To describe and evaluate a novel, webinar-based Evidence-to-Recommendation (EtR) training program designed for NITAGs.
• To assess the effectiveness of this training in supporting evidence-based decision-making for hexavalent vaccine introduction.

Main Methods:

• A five-part webinar series on the hexavalent vaccine transition was delivered between January and June 2025.
• The training utilized a cohort-based model for regional peer learning and focused on identifying evidence across EtR domains.
• Effectiveness was evaluated using post-webinar surveys and virtual key informant interviews.

Main Results:

• NITAGs from 32 countries participated, with many rating the webinars as highly useful.
• Participants particularly valued country experiences, practical guidance on EtR domains (feasibility, resources), and peer learning.
• Qualitative feedback indicated strong interest in continued support, peer-to-peer learning, and operational guidance.

Conclusions:

• The webinar-based EtR training is an effective and valued approach for supporting NITAGs in evidence-informed decision-making for vaccine transitions.
• Peer learning and practical guidance are crucial components for successful implementation of new vaccine introductions.
• Continued technical and operational support is essential for NITAGs to strengthen immunization systems.
