Valneva and Instituto Butantan Launch Pilot Vaccination Campaign Against Chikungunya in Brazil
Valneva SE and the Instituto Butantan announce the initiation of a pilot vaccination campaign in Brazil using IXCHIQ®, a single-dose vaccine against chikungunya. This pilot vaccination strategy will serve as a basis for post-marketing studies to be conducted following the vaccine's approval.
The pilot vaccination campaign will be deployed in ten Brazilian municipalities selected based on epidemiological and operational criteria. In accordance with the current authorization of IXCHIQ® in Brazil, adults aged 18 to 59 are invited to participate, with a vaccination coverage goal of 20% to 40% of the target population. This campaign has been jointly decided by the Brazilian Ministry of Health and the Instituto Butantan.

Valneva will provide up to 500,000 doses of IXCHIQ® to the Brazilian Ministry of Health through the Instituto Butantan to support this program. The campaign aims to evaluate the vaccine's efficacy and safety under real-world conditions and to generate data across a broad population. IXCHIQ® was granted marketing authorization in Brazil in April 2025 by ANVISA, marking the first global approval of a chikungunya vaccine in an endemic country.
