One of the most promising world researches for the development of an AIDS vaccine is taking place at the Federal University of Pernambuco (UFPE), in partnership with the University of Paris 5.
In the first phase, entirely developed in Recife, the capital of the Northeastern Brazilian state of Pernambuco, 18 patients who carried the virus were submitted to three doses of the experimental vaccine. Just one day after immunization, the viral load in these volunteers had dropped on average 80%.
In eight of them, the reduction was as high as 90%. Within two months a group of 40 patients is going to receive a stronger dosage, and a new phase of the history against the Acquired Immunodeficiency Syndrome may start being written.
Made from an inactive HIV virus, the immunizer also uses dendrites from the patient himself. These cells are in charge of showing the body's defense cells which are the invaders.
The Aids virus normally manages to kill them before they do their job. The objective of this vaccine is to halt this.
It is not, however, a vaccine to avoid contamination by the HIV virus. The objective of the medication is therapeutic, i.e., for the treatment of patients who are already HIV positive.
"Our expectation, in phase two, is to come close to 100% reduction," stated infectologist Luiz Cláudio Arraes, a professor at the Tropical Medicine Department of the UFPE, during an interview to the Trade Newspaper.
Despite the researcher's optimism, the arrival of this medication on the market may still take 10 years.
The research being developed in Brazil is the first in the world to present such significant results. India and China also started testing a vaccine, but the success of this research cannot yet be measured.
Other initiatives, however, also showed great interest. At the end of last year, Israeli researchers from the Hadasa University Hospital in Jerusalem and from the Weizman Science Institute developed a medication to strengthen the immune system. The drug proposes to reduce the cracks that are used by so called "opportunist diseases".
Aids is considered the infectious contagious disease that most kills in the world. The estimate is that in 2004 40 million people were infected by the HIV virus.
In Brazil, between 1980 and 2002, a total of 257,000 cases were registered. In other times, different diseases frightened humanity.
In the 1950's, for example, 50 million people were infected with cowpox. Today, the disease is considered eradicated worldwide.

The small, coastal town of Condé is located just a twenty minute's drive from João Pessoa, the capital of Paraíba. The Northeast of Brazil has historically been a place of encounter and mixing between peoples. For millenia groups of indigenous people fished, farmed, migrated and sometimes fought along this large, fertile area. 
The Brazilian diplo-MÁ-cia (bad diplomacy) carries on its accelerated course towards the non-acknowledgment of human rights, although sometimes it takes pleasure in saying that it does precisely the opposite. The visit of Iran's president, Mahmoud Ahmadinejad, is another example of a diplomatic omission that verges on hypocrisy. 
On July 4, 2006, representatives of Argentina, Brazil, Paraguay and Uruguay met in Caracas to sign the protocol for the entrance of Venezuela into the Southern Common Market (Mercosur). After two and a half years, the protocol was approved by the legislative bodies of Argentina and Uruguay, and as of now it may be only days away from being ratified by the continent's economic megalith, Brazil. 
Some sectors of the fight against AIDS have suggested that Thabo Mbeki, the former president of South Africa, committed genocide through his absence from the fight against the illness in his country throughout his two terms. 
One hundred and eleven years after Brazil abolished slavery, the number of workers deprived of their freedom is still huge. They raise cattle, produce charcoal, sugar cane or timber. Some of them, most undocumented Bolivians, work in basements of small apparel factories in São Paulo and other metropolis. 
On November 7, 2009 a few friends and I had an opportunity to take a look inside a Brazilian jail outside the city of Rio de Janeiro. We were able to take some amateur footage of our experience on video (see link below). It's no surprise, of course, that the typical Brazilian jail lacks some of the functionality of those in North America or Europe, but our experience that day was quite shocking. 
Depletion of the Amazon Rainforest is not a new concern facing environmentalists, biologists, ecologists, and a growing number of the Amazonian indigenous peoples. For decades they have feared for the fate of the world's most biologically diverse and species-rich hothouse. 
Geisy Arruda made history this week in Brazil, but for all the wrong reasons. What began as a poorly planned fashion statement has become a worldwide tale. Geisy decided to wear a pink mini-dress to her private college in São Paulo state, and after that, all hell broke loose. 
The push of vigilante groups in Rio de Janeiro's favelas (shantytowns) in the last three years is the most important and alarming information of the just-released study by the Rio de Janeiro University's Violence Research Center (Nupev-Uerj). 
A dispute over drug trafficking territory in Rio de Janeiro has intensified lately, leaving in its wake unprecedented acts of violence, such as the downing of a police helicopter in the northern zone of the city on October 17. Three policemen died and another two were injured. This event has drawn the attention of the international media, who are raising the issue of public security for the 2016 Olympics to be held in Rio.
