Consumer willingness to pay for a hypothetical Chagas disease vaccine in Brazil: a cross-sectional study and the implications

Abstract

Aim: Chagas disease is a serious public health problem, endemic in 21 countries in Latin America. A future vaccine can contribute to decreasing the number of cases and its complications. Methods: A cross-sectional study was conducted with residents of the northern region of Brazil, on the willingness to pay for a hypothetical vaccine against Chagas disease (effective protection of 80%). Results: We interviewed 619 individuals and seven were excluded from the analysis and the value of willingness to pay was US$23.77 (100.00 BRL). Conclusion: The Northern region of Brazil is one of the largest markets for this vaccine, due to its epidemiological relevance, so economic studies with this vaccine will be important to assist in the assessment of technologies.

Acceptability and willingness to pay for a hypothetical vaccine against SARS CoV-2 by the Brazilian consumer: a cross-sectional study and the implications

“…Some economic studies can contribute to technology pricing discussion applied to its incorporation in a public health system (government purchase) as cost effectiveness analysis [89], and to private market such as the WTP approach [55][56][57][58]65]. In this last analysis, it is essential to consider the socioeconomic and epidemiological aspects of a region along with the purchasing power of an individual in the region [56,58].…”

“…Some economic studies can contribute to technology pricing discussion applied to its incorporation in a public health system (government purchase) as cost effectiveness analysis [89], and to private market such as the WTP approach [55][56][57][58]65]. In this last analysis, it is essential to consider the socioeconomic and epidemiological aspects of a region along with the purchasing power of an individual in the region [56,58]. This study demonstrated the profile of Brazilian people and its WTP for a hypothetical vaccine against COVID-19 associated with a number of variables including income range, education level, and locality, and can be useful in decisions regarding the purchasing and selling price of a vaccine against SARS-CoV-2 in Brazil.…”

“…In recent years, this methodological approach has enhanced deliberations regarding the potential value of new vaccines, i.e. the first approved dengue vaccine in Brazil, and to hypothetical scenarios for Zika and Chikungunya as well as Chagas Disease in the country [55][56][57][58]. Some published studies already assessed the WTP for a vaccine against SARS-CoV-2 infection [59][60][61].…”

Evidence-based public policy making for medicines across countries: findings and implications for the future

“…Independent willingness-to-pay (WTP) as well as other preference elucidation studies are also being conducted pre-pricing deliberations in some countries to help health authorities with subsequent pricing deliberations especially given increasing concerns with the lack of transparency with suggested prices [96][97][98][99][100]. We have seen WTP activities grow in countries such as Brazil with important implications for future pricing deliberations [96,98,101].…”

Willingness to pay for a hypothetical malaria vaccine in Brazil: a cross-sectional study and the implications

“…The interviews were conducted by undergraduates of health courses, mainly by students of the Bachelor of Public Health course from the Federal University of the South and Southeast of Pará (UNIFESSPA). All interviewees were trained by the researcher responsible for this study (IPDG) according to recommendations from previously published studies [31,34,41,42,46,47].…”
