Population resistance against COVID vaccination in Brazil

Abstract

Vaccination hesitation is defined as the act of refusing or delaying, despite their availability, the administration of recommended vaccines. The refusal, in turn, is the result of doubts or own convictions regarding the safety and efficacy of the vaccine. The present study is justified by the health professionals assisting patients who have doubts and/or fears about the safety and/or efficacy of vaccines. The present research aims to describe, through a literature review, the causes of hesitation in the vaccine against covid-19. The present study used the integrative literature review as a method, which aimed to gather and summarize the scientific knowledge already produced on the investigated topic, that is, it allows searching, evaluating and synthesizing the available evidence to contribute to the development of knowledge in the theme. As a result, vaccines against Covid-19 were prepared to provide extensive preservation against the virus and offer some level of protection against several variants. Over time, various vaccination practices may be indispensable as new variants appear. This could include modifying the vaccine dose, extra booster vaccinations, combination vaccines or tailoring the vaccines themselves to the target variants. It is concluded that above hygiene and social distance prevention, immunization is the only concrete way to prevent COVID-19. Vaccines are essential for preventing vaccine-preventable diseases that have a benefit confirmed through data and scientific studies.
