Abstract

Introduction: The Human Immunodeficiency Virus (HIV) is one of the greatest public health challenges still facing communities worldwide, and until this moment, no vaccine is available for its prevention. In Brazil, the Rio de Janeiro State has stood out regarding the prevalence of this disease. As a result, an important state to consider the Willingness to Pay (WTP) for a hypothetical HIV vaccine to help with future pricing.

Methods: A cross-sectional study was conducted to assess the acceptability and WTP of individuals from Rio de Janeiro State for a hypothetical HIV vaccine with a 70% efficacy.

Results: 600 individuals were interviewed and the acceptability for this hypothetical vaccine was 77.2%. In addition, 452 participants were eligible for the WTP analysis and would accept a WTP US$79.37 (400 BRL) for this vaccine, a higher value than that found in another study (200 BRL) conducted in the Northern region of Brazil under the same methodological conditions.

Conclusion: Economic studies such as WTP can contribute to discussions regarding the prices and specifications for future vaccines, particularly for a HIV vaccine in countries such as Brazil with over 5,000 municipalities spread across regions with diverse characteristics and challenges in terms of socioeconomic, epidemiological and cultural differences.

巴西对假定的艾滋病疫苗的接受度和支付意愿及其影响：一项横断面研究。

导言：人类免疫缺陷病毒（HIV）是全球社会仍然面临的最大的公共卫生挑战之一，直到现在，还没有疫苗可以预防这种疾病。在巴西，里约热内卢州的艾滋病流行情况尤为突出。因此，里约热内卢州是考虑假定的艾滋病疫苗支付意愿（WTP）的一个重要州，有助于未来的定价：方法：我们开展了一项横断面研究，评估里约热内卢州的个人对有效性为 70% 的假定 HIV 疫苗的接受度和 WTP：对 600 人进行了访谈，他们对这种假定疫苗的接受度为 77.2%。此外，452 名参与者符合 WTP 分析的条件，他们对该疫苗的 WTP 值为 79.37 美元（400 BRL），高于在相同方法条件下在巴西北部地区进行的另一项研究（200 BRL）：WTP等经济研究有助于讨论未来疫苗的价格和规格，尤其是在巴西这样拥有5000多个市镇的国家，这些市镇分布在各地区，在社会经济、流行病学和文化差异方面具有不同的特点和挑战。
