The Mission of Brave: a person-centred educational program to transform paediatric radiotherapy into an empowering adventure.

Established in 1973, Brazil’s National Immunization Program ( - PNI) is considered one of the country’s most significant public health achievements. The program provides high-quality vaccines to populations throughout the national territory and has contributed substantially to improving public health outcomes in Brazil. Despite the undeniable success of PNI over the years, a progressive and concerning decline in vaccination coverage has been observed globally and in Brazil since 2016, a trend that was further exacerbated by the COVID-19 pandemic. According to data from the Brazilian Ministry of Health (MoH), vaccination coverage (VC), which reached 97% in 2015, declined to 75% in 2020. Furthermore, according to the World Health Organization (WHO), nearly 26% of the pediatric population in Brazil had not received any vaccine doses in 2021. The decline in VC results from multiple factors, including vaccine hesitancy, defined as the delay in acceptance or refusal of vaccination despite the availability of vaccination services. In 2019, the WHO identified “vaccine hesitancy” as one of the ten greatest threats to global health. Vaccine hesitancy may be influenced by several factors, including complacency, convenience, and confidence. Complacency occurs when the perceived risks of vaccine-preventable diseases are low and vaccination is not considered a necessary or important preventive measure. Convenience refers to factors that influence vaccination decisions based on the accessibility and availability of vaccines, including physical availability and geographic access. Confidence encompasses trust in the effectiveness and safety of vaccines
