BILL GATES :HIS FIGHT AGAINST THE MALARIA
Left: Spaniard Researcher Dr. Pedro Alonso.
The biggest merits of Bill Gates, will not be his innovations in software global needs. We foresee, that his greatest achievement -for which he will be remembered- will be one in which he and his wife Melinda, are working feverishly :a Foundation whose goal number one, is the eradication of malaria globally (which kills 1 million Africans every year, of which 90% are children under age 5, living in the african SubSahara). To that end his Foundation has injected to a conglomerate of scientific institutions: $ 380 million dollars, to a total of $ 1 billion that already has the Herculean undertaking. The attack against malaria is carried by his most obvious side: immunization of children under 12 months, against Plasmodium Falciparum. We dream of someday, to fit the genomes of human blastocyst of 32 cells, with antigens against all endemic infections and infestations worldwide.
The vaccine chosen (RTS, S), consists of a recombinant protein that merge a portion of the circunsporozoit protein of P. Falciparum, with a surface antigen of hepatitis B virus, generating production of antibodies and white blood cells, diminishing the ability of the parasite to infect, to survive and develop in the human liver, as well as stimulating a protective immune response against the virus Hepatitis B. The vaccine developed since 1987 by GSK (Glaxo Smith Kline) and worked in children by experts from the University of Barcelona (Dr. Pedro Alonso), proved successful in 2002, when tracks realized showed protection for 6 months. Since 2005, it is known that the protection is more durable (18 months). Currently, 1442 african children (Tanzania), under 12 months receive 3 doses in order to asses the safety, immunogenicity and efficacy of the vaccine, which so far reduces episodes of severe malaria, up to 50% of times.

BILL GATES Y LA MALARIA
Los méritos más grandes de Bill Gates, no serán sus innovaciones en softwares de necesidad mundial. Intuimos, que su logro más grande -por el que será recordado- será uno en el que trabajan febrilmente, él y su esposa Melinda : una Fundación cuyo objetivo número 1, es la erradicación de la Malaria a nivel mundial (que mata 1 millón de africanos cada año, de los cuales el 90 %, son niños menores de 5 años, radicados en el SubSahara africano). Para ello su Fundación ha inyectado a un conglomerado de instituciones cientificas : 380 millones de dólares, al total de 1 billón de dólares con que ya cuenta la ciclópea empresa. El ataque contra la malaria se realiza por su lado más obvio : inmunización a niños menores de 12 meses, contra Plasmodium Falciparum. Soñamos con que algún día, se acoplen a los genomas de blastocistos humanos de 32 células, antígenos contra todas las infecciones e infestaciones endémicas mundiales.
La vacuna escogida (RTS, S), se compone de una proteína recombinante que mezcla una parte de la proteína del circunsporozoito del P. Falciparum, con el antigeno de superficie del virus de la Hepatitis B, generando producción de anticuerpos y glóbulos blancos, atenuando la capacidad del parásito para infectar, sobrevivir y desarrollarse en el hígado humano, además de estimular una respuesta inmune protectora contra el virus de la Hepatitis B. La vacuna desarrollada desde 1987 por GSK (Glaxo Smith Kline) y trabajada en niños por expertos de la Universidad de Barcelona (Dr. Pedro Alonso), probó ser exitosa en el 2002, cuando seguimientos dieron cuenta de una protección por 6 meses. Desde el 2005, se sabe que la protección es más duradera (18 meses). Actualmente, 1442 niños africanos (Tanzania), menores de 12 meses, reciben 3 dosis que valorarán la seguridad, la inmunogenicidad y la eficacia de la vacuna, que hasta el momento reduce los episodios de Malaria severa, hasta en un 50 %, de veces.
