Rebuilding vaccine confidence in Latin America and the Caribbean: strategies for the post-pandemic era.

Introduction: Vaccine hesitancy in Latin America and the Caribbean (LAC) has a complex nature. It is shaped by socio-political, cultural, economic factors, and an influence of the COVID-19 pandemic on increasing hesitancy patterns. While LAC has maintained high vaccination coverage, it has experienced a decline over the past 10-years, further exacerbated by declining vaccine confidence during the pandemic, driven by misinformation, political polarization, and conspiracy theories.

Areas covered: We review the impact of vaccine hesitancy across various stakeholders in LAC, focusing on healthcare professionals, parents, and community leaders, including data from studies conducted in Argentina and Colombia highlighting regional variations in hesitancy patterns. It describes the role of pediatricians in recommending vaccines, particularly in COVID-19 vaccines. The study explores how the rapid spread of misinformation, particularly through social media, exacerbated mistrust, and offers an overview of vaccine hesitancy trends in LAC during/after the pandemic.

Expert opinion: While vaccine acceptance remains high among certain populations, communication strategies are essential to address concerns about vaccine safety. It is imperative to strengthen the relationship between health-providers and the public to mitigate misinformation and improve vaccine uptake. We propose seven strategic approaches for a comprehensive communication aimed at changing the public behavior about vaccines.
