Strengthening the EU Health Technology Assessment Regulation: Integrating National Immunization Technical Advisory Groups for Comprehensive Vaccine Assessments

BACKGROUND: Given their crucial role in vaccine assessment, National Immunization Technical Advisory Groups (NITAGs) should be considered in the Regulation on Health Technology Assessment (EU HTAR) to maximize the benefits of the EU HTAR for vaccines. This review and perspective piece identifies the gaps arising from NITAGs potential lack of involvement and proposes strategies for involving them. METHODS: A targeted literature and guideline review was conducted to evaluate NITAGs' current and future role in relation to the EU HTAR. The impact of the EU HTAR on diverse national HTA frameworks was explored in a three-country case study. Recommendations were developed to leverage strengths and address weaknesses to ensure consistent and cohesive vaccine assessments. RESULTS: The case study revealed potential overlaps between NITAGs and the EU HTAR, particularly regarding horizon scanning and joint scientific consultations. The involvement of NITAGs in national assessments varies, influencing how well joint clinical assessment reports will ultimately align with and be applicable to individual Member States. CONCLUSIONS: Stronger consideration of vaccines within the EU HTAR and NITAG involvement can streamline assessments, reduce duplication, and improve alignment between European and national processes. Strategic actions, including capacity building and collaborations between NITAGs, are key in facilitating this process.
