Cobertura vacinal no Brasil

Abstract

Introduction: Vaccination is an effective, safe and simple way to protect people against some diseases, even before contact with them. In a temporal analysis of vaccination coverage, two years stand out for low vaccination, 2016 and 2019. The resurgence of diseases already eradi-cated in Brazil and the low demand for vaccines becomes a public health problem. Objectives: Analyze the reasons that led to low vaccination coverage and how this has impacted the Bra-zilian population. Methodology: This is a literature review. Where the material used in this research was identified in the Latin American and Caribbean Literature in Health Sciences (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE) data-bases. Results and Discussion: 10 articles were selected that identified misinformation about vaccines as the main factor that negatively interferes with vaccination adherence. The bond with health professionals is the factor that most positively influences. The media mostly influ-ences negatively due to untrue information on the internet. The reintroduction of diseases al-ready extinct in the country was cited as the biggest consequence of low coverage. Aiming to improve this, several actions were created by the Ministry of Health, including the creation of the 3C's of the determinants that lead to vaccine refusal: trust, complacency and coexistence. Conclusion: The study allowed us to conclude that several factors influence the population, whether encouraging the search for vaccination or contributing to refusal. Keywords: Vaccination coverage and vaccination refusal.
