The median individual maximum WTP for a hypothetical malaria vaccine was US$11.90 (BRL 50). <b>Conclusion: </b>The northern region of Brazil is one of the largest markets for a malaria vaccine due to its epidemiological relevance. Consequently, economic studies will be important to assist in the assessment of the potential price and value of new vaccines.
