Abstract
Chickenpox, a highly contagious viral infection, represents a significant public health challenge, especially in varied regional and population contexts. Immunization is the main strategy to prevent the disease, but its effectiveness is directly related to vaccination coverage. This study aims to investigate how varicella vaccination coverage and vaccine safety vary between different regional and population contexts, and to identify the main challenges faced in implementing vaccination programs. An integrative literature review was carried out, analyzing studies and data available in SCIELO, LILACS, SCOPUS and ScienceDirect databases. The results indicate a significant variation in vaccination coverage rates between different regions, with urban areas generally showing higher immunization rates compared to rural areas. In addition, the safety of the vaccine was corroborated by the low incidence of serious adverse events, suggesting an acceptable safety profile. Challenges in implementing vaccination programs include vaccine hesitancy, misinformation and unequal access to health services. Promoting information campaigns and improving access to vaccination are key to increasing coverage and ensuring protection against varicella. This study highlights the importance of adaptive strategies that consider regional particularities to maximize the effectiveness of vaccination programs.
