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

Abstract

INTRODUCTION\nThe new coronavirus pandemic has appreciably impacted morbidity and mortality, as well as having an economic impact worldwide. New vaccines are a potential way forward to reduce transmission rates and subsequent infection. In Brazil, vaccines are being distributed via the public sector though in the future, they will be available in the private market. Information about consumers willingness to pay (WTP) for a hypothetical vaccine against SARS CoV-2 can help future price setting discussions.\n\n\nMETHODS\n: A cross-sectional study was conducted with consumers in the five regions of Brazil regarding the WTP for a hypothetical vaccine against SARS CoV-2 with a 50% efficacy.\n\n\nRESULTS\n: A total of 1402 individuals over 18 years of age who declared not having COVID-19 at the time of the survey were interviewed. The acceptability for this hypothetical vaccine was 80.7%. In addition, the amount of WTP by Brazilian consumers for a hypothetical SARS CoV-2 vaccine was estimated at US$ 22.18(120.00 BRL).\n\n\nCONCLUSION\n: This study can contribute to decision-making to inform potential pricing for a hypothetical SARS CoV-2 vaccine.
