[The royal philanthropic expedition of the vaccine (Xavier de Balmis/Josep Salvany). 1803-1806]. / La real expedición filantrópica de la vacuna (Xavier de Balmis/Josep Salvany): 1803-1806.

Six years after Jenner discovered the anti-smallpox vaccine, King Charles IV mandated the initiation of vaccination campaigns throughout his kingdom. The overseas campaign was coordinated by the Valencian military doctor Xavier de Balmis with the aid of the Catalan Josep Salvany. The vaccine was transported to America "in vivo" in 22 children. The expedition departed from La Coruña on November 1806 and arrived to the Venezuelan port of La Guayra where it was split in two: One sub expedition under the order of Josep Salvany, continued by land to Colombia, Ecuador, Peru and Bolivia. Salvany died in the Bolivian city of Cochabamba. The other sub expedition, leaded by Balmis himself, continued by sea to Cuba and Mexico. From Acapulco it arrived to Manila and from there to Macau followed by inland penetration into China.

Older children and adolescents surviving with vertically acquired HIV infection.

This article describes the characteristics of children infected vertically with HIV surviving 10 years or more who were enrolled in the prospective European Collaborative Study. Thirty-four of 187 infected children were identified with a median age of 11.4 years (range, 10.1-15.9 years). Factors examined included clinical status, immunologic and virologic characteristics, type of antiretroviral therapy, and psychosocial characteristics. By 10 years of age, 6 (18%) children had progressed to Class A as determined by the system of the U.S. Centers for Disease Control and Prevention (CDC), 17 (52%) to class B, 7 (21%) to class C, and 3 (9%) had remained asymptomatic. At 73% (904 of 1234) of scheduled clinic visits, these children had no symptoms of HIV disease. Most children were in CDC immune categories 1 (18, 56%) or 2 (11, 34%) at their last visit. Three quarters (24 patients) were on combination therapy with three or more drugs, although 3 children had never received any antiretroviral therapy. Nineteen (56%) children were living with at least 1 parent and the mothers of 13 (38%) children had died. Most (77%) children had been told about their HIV infection. Children infected vertically with HIV who have survived their first 10 years are mainly free of serious symptoms. As they enter adolescence, additional services are needed including support with disclosure to others, therapy, and sexual health.
