While a widely available dengue vaccine for the entire population is still under development, there is reason for optimism. The Butantan Institute,a leading authority in vaccine research,has made a groundbreaking announcement. They are set to produce the first single-dose dengue vaccine, ushering in a new era of hope for widespread vaccination in Brazil. This development has the potential to significantly impact the control and prevention of dengue in the region.
A groundbreaking new dengue vaccine developed by the Butantan Institute, officially named Butantan-DV, is poised to revolutionize the fight against this mosquito-borne disease. Director Esper Kallás reveals that the institute aims to produce a remarkable 100 million doses of this innovative vaccine within the next three years.
Production has already commenced at the institute’s Bioindustrial Center,with initial batches being meticulously refined and improved. This phased approach indicates a commitment to quality and efficacy.Production projections are enterprising: 1 million doses in 2025, scaling up to 60 million in 2026 and 40 million in 2027.
The single-dose nature of Butantan-DV represents a significant advantage for widespread distribution and public health initiatives. As Kallas anticipates a challenging 2025 due to a predicted surge in dengue cases in brazil, this efficient delivery system will be crucial for maximizing vaccine accessibility and impact.
Butantan-DV is a tetravalent vaccine, designed to offer comprehensive protection against all four dengue virus serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. This crucial feature safeguards individuals against the possibly severe consequences of recurrent infections.
The vaccine has undergone rigorous testing in phase 2 and phase 3 clinical trials, involving approximately 17,000 volunteers.These studies have yielded notable results, demonstrating a high safety profile and an efficacy rate of 80% in preventing dengue infection during the initial two years following vaccination. Furthermore, Butantan-DV has been shown to provide 88% protection against severe dengue manifestations.
The vaccine’s journey to market is well underway, with the complete regulatory package submitted to Anvisa, Brazil’s National Health Surveillance Agency, in December 2022. This extensive package necessitates a thorough evaluation of a vast amount of data, a process that is expected to culminate in a final decision between March and April 2024.

A landmark development in the fight against dengue fever has emerged, with volunteers participating in trials demonstrating a remarkable response to a new single-dose vaccine. the vaccine, being developed by the Butantan Institute, has been met with incredible initial success.
According to experts, the vaccine is remarkably well-tolerated by recipients. “The vaccine is extremely well tolerated and effective,” confirmed Dr.Kallás, highlighting the promising results observed so far. The most common reported side effect was mild, temporary skin irritation, a clear indication of the body’s immune system responding effectively to the vaccine.
This breakthrough single-dose vaccine represents a significant leap forward in tackling dengue fever,a mosquito-borne illness that poses a major global health threat.The Butantan Institute’s ambitious project, announced on January 27, 2025, by Julio Silva, holds immense potential to change the landscape of dengue prevention and control.
