Technology 2.0

ButanVac was announced in March 2021, as a vaccine that uses a “technology 2.0”, as defined by the director of Butantan at the time, Dimas Covas. Its production works by inoculation in an embryonated egg, using the viral vector technique.

The immunizer uses the inactivated Newcastle Disease virus – which only infects birds, without symptoms in humans – to take the coronavirus protein and generate the production of antibodies. This process facilitates manufacturing on an industrial scale with the Institute’s current infrastructure, which makes costs cheaper.
