Vaccines are among the most effective public health interventions, but access is still unequal. This Public Health World Conference (PHWC)session will examine progress in vaccine research, production, and fair distribution. Specialists will debate the contribution of public-private partnerships to the scale-up of immunization programs. Successful global vaccination campaigns and lessons learned from recent pandemics will be presented through case studies. Participants will hear about how to address vaccine hesitancy and disinformation. The meeting will also touch on the potential of new vaccine technologies to drive preparedness for future outbreaks.
