ASPECTS THAT INTERFERE WITH ACCESS TO VACCINATION: A REVIEW OF THE STATE OF THE ART

Abstract

Introduction: The research objective of this study was to outline the factors that influence vaccination, based on scientific publications.Objective: To identify how access to vaccination has been discussed in the national scientific community in recent years by conducting a bibliographical search on the topic. To identify scientific articles that address access to healthcare services and vaccination to aid in understanding the topic. Methods: This study was conducted through a bibliographic search of scientific articles in the Medline, Scielo, Lilacs, and BVS databases. The descriptors used were: "Immunization Program" AND "Access to Health Services," "Vaccination" AND "Access to Health Services," and "Vaccine Refusal" AND "Access to Health Services." The search yielded 1,098 articles. After filtering for full text and English or Portuguese, we obtained 283 titles. From these, we excluded duplicate articles, articles that were not related to the proposed topic, or were published more than five years ago, resulting in a final total of 25 articles.Results: This documentary search found publications that reflected on accessibility in Brazil, and organizational and planning aspects of the healthcare workflow. Access barriers, both geographical and related to the physical structure of the facilities, were also mentioned in the articles searched. Perceptions from a user perspective about network equity and vulnerabilities appeared in few publications, demonstrating their scarcity in the field.Conclusions: Studying the daily routine of vaccination rooms in family health units and analyzing the perceptions of those involved in vaccination services can demonstrate ways of producing work that contribute to ensuring equal access to health care.
