Brazil Sets Jan. 17–18 Start for Single-Dose Dengue Vaccine Pilot in Three Cities

Overview

• Vaccinations begin Jan. 17 in Nova Lima and Maranguape and Jan. 18 in Botucatu, targeting residents 15–59 with Butantan-DV to rapidly reach roughly 40–50% coverage.
• Primary care health workers will be vaccinated first, then eligibility will move from people aged 59 down to 15 as doses become available.
• The initial phase uses about 300,000 doses supplied to the National Immunization Program and draws from an early stock of 1.3 million, with production set to expand via a WuXi technology transfer.
• Anvisa authorized the single-dose vaccine for ages 12–59 after trials showed about 74.7% overall efficacy and strong protection against severe disease and hospitalization.
• The SUS will continue offering the two-dose QDenga to 10–14 year olds, and both dengue vaccines are not indicated for people 60 or older, pregnant women or immunocompromised individuals.
