The objectives of this forthcoming consultation will be to review the available evidence on the efficacy and effectiveness of vaccines being deployed in terms of:
emerging variants effect on protection levels,
duration of protection,
safety of booster vaccines and
research to evaluate various delivery strategies.

During the consultation, experts will debate the methodological strength and limitations of existing data and the potential designs to generate additional data leading to evidence-based decisions.

Available randomized and non-randomised data on COVID-19 vaccines duration of protection and methodological challenges with its interpretation.
Opportunities and designs to be considered in the generation of additional data.
Vaccine developers update about their current progress and plans to generate evidence to inform discussions on the need and pertinence of booster vaccines.

Invited experts will include:
Global experts on evidence synthesis and critical appraisal of evidence.
Leading researchers on COVID-19 vaccine studies.
Clinical trials and observational studies methodologist.
Vaccine developers.
