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

INTRODUCTION: The 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; however, 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. METHODS: 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. RESULTS: 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). CONCLUSION: This study can contribute to decision-making to inform potential pricing for a hypothetical SARS CoV-2 vaccine.
