Brazilian scientists to test AIDS vaccine

Publicado em 06 agosto 2013

BRAZILIAN scientists have developed an HIV vaccine and plan to begin testing on monkeys later this year.

Known as the HIVBr18, the vaccine against the virus that causes AIDS was developed and patented by a team from the Medicine Faculty of the University of Sao Paulo, the Sao Paulo state Research Foundation (FAPESP) said on Monday.

The scientists say that at its current stage of development, the vaccine will not totally eliminate the virus from the organism.

But the vaccine will be able to maintain it at a viral load low enough that the infected person will neither develop an immunodeficiency nor transmit the virus.

The foundation says the monkey trials are expected to last two years.

"Our goal is to test various immunisation methods to select the one capable of inducing a stronger immunological response and thus be able to test it on humans," FAPESP quoted Cunha Neto as saying.

Provided adequate funding is available, the first clinical trials could then be launched, it added.

Work on the vaccine began in 2001 and the research team - Edecio Cunha Neto, Jorge Kalil and Simone Fonseca - plan to test it on a colony of rhesus monkeys provided by Sao Paulo state's Butantan biomedical research institute.

The monkeys were chosen for the test because their immune system is similar to that of humans and they are susceptible to SIV (Simian immunology Virus), which is believed to have led to HIV when it crossed the species barrier.
