Brazil Against Zika Virus

A new generation DNA-based Zika vaccine has been found safe and effective at eliciting an immune response against the virus in early human clinical trials, scientists say. The GLS-5700 vaccine contains the synthetic DNA instructions for the host to learn how to mount an immune response against a specific Zika virus antigen.

In May, as the first cases of the Zika virus were being detected in Brazil, Rossandra Oliveira stopped receiving a critical tool she needed to do her job: insecticide.

The head of the World Health Organization expressed confidence Tuesday that Brazil can host the Rio Olympics safely despite the Zika threat, while warning of a long battle against the mosquito-borne virus.

Brazilian authorities in the southern city of Joinville are warning residents to guard against fraudsters after three thieves posing as health workers working to wipe out the Zika virus entered a home and ran off with cash and electronics.

Brazil's government launched a nationwide campaign on Saturday to fight the Zika virus, with President Dilma Rousseff and cabinet ministers personally visiting homes and handing out leaflets along with 220,000 troops.

Brazil's health minister is calling on residents to join the government's battle to eliminate Zika, saying that keeping homes free of mosquitoes is the most-effective way to contain the virus.

Leading researchers in Brazil are borrowing techniques used to accelerate the fight against Ebola in the hope of developing a Zika virus treatment that could be tested in humans in a year.

Brazilian President Dilma Rousseff vowed Wednesday to wage a "house-by-house fight" against Zika, the virus blamed for causing a surge in brain-damaged babies and sowing fear ahead of the 2016 Olympics.

Brazil's health minister says the country is sending some 220,000 troops to battle the mosquito blamed for spreading a virus suspected of causing birth defects - but he also says the war is already being lost.
