Rio de Janeiro, Brazil & Brussels, Belgium — September 2026
Bio-Manguinhos/Fiocruz and Quantoom Biosciences today highlighted a major milestone in Brazil’s mRNA vaccine development: Anvisa, Brazil’s National Health Surveillance Agency, has authorized the start of clinical trials for the country’s first mRNA vaccine, developed on Bio-Manguinhos/Fiocruz’s proprietary mRNA platform, supported by Quantoom Biosciences’ Ntensify® technology for RNA production and purification.
This authorization positions Bio-Manguinhos/Fiocruz as the first partner within the WHO Global mRNA Technology Transfer Programme and the Medicines Patent Pool (MPP) initiative to advance a product to clinical trial stage. Fiocruz’s pilot plant is also the first in Latin America to hold Good Manufacturing Practice (GMP) certification for RNA production.
The vaccine, targeting COVID-19 as a booster dose in line with Brazil’s National Immunization Program, completed preclinical, toxicology and scale-up studies before receiving Anvisa’s authorization. Participant recruitment for Phase 1 is scheduled to begin in the first quarter of 2027, pending Research Ethics Committee approval.
Building National mRNA Manufacturing Capacity
This milestone demonstrates the feasibility of an end-to-end mRNA manufacturing ecosystem, enabling:
- Rapid vaccine design and production supporting national health-emergency preparedness
- Local manufacturing capability reducing reliance on external technologies.
- A scalable platform for future products, including candidates against leishmaniasis, tuberculosis and cancer already under study
Quantoom’s RNA production and purification technologies contributed to development activities conducted within Bio-Manguinhos/Fiocruz’s national mRNA platform, supporting efforts to expand local manufacturing capabilities and strengthen regional technological autonomy.
“Seeing Ntensify support Fiocruz’s journey to Brazil’s first mRNA vaccine reaching clinical trials is a powerful demonstration of how our technology enables national platforms to move from lab to patient,” said José Castillo, CEO, Quantoom Biosciences.
About Bio-Manguinhos/Fiocruz
Bio-Manguinhos/Fiocruz is Brazil’s Institute of Technology on Immunobiologicals, part of the Oswaldo Cruz Foundation (Fiocruz). Recognized by WHO since 2021 as a reference center for mRNA vaccines in Latin America, Bio-Manguinhos leads Brazil’s mRNA platform under the Program for the Expansion and Modernization of the Health Economic-Industrial Complex (PDCEIS), with funding from the Ministry of Health, BNDES and PAHO.
About Quantoom Biosciences
Quantoom Biosciences is a full-stack RNA partner dedicated to accelerating the development and manufacturing of mRNA- and saRNA-based vaccines and therapeutics. Founded in June 2021 by José Castillo, Quantoom built the N-Force™ toolbox — combining Ncode™ for sequence design and optimization, Ntensify® for construct-agnostic RNA production, and Ncapsulate® for RNA-LNP formulation — to give partners an integrated path from sequence to patient. Ntensify®, launched in 2023, scales seamlessly from microgram-scale research experiments to multi-gram and GMP-grade commercial manufacturing, and has been adopted by research institutions, biotechs, and CDMOs around the world.
