[I]n Santiago del Estero, an Argentine province…[a]5-month-old died…[She]had been one of more than 13,000 Argentine children to participate in a clinical study implemented…by…GlaxoSmithKline…to test the efficacy of [an] experimental pediatric pneumonia vaccine…Because of the multinational business of major drug companies…as well as consumers of drugs that will be available in the U.S. market, there are global ramifications of clinical testing being conducted around the world. The lion's share of drug studies has gone to regions with "emerging markets": Eastern Europe and Central Europe, Latin America, and south and Southeast Asia…Conducting trials in regions considered "poor" by Western standards makes economic sense...GlaxoSmithKline denies allegations of ethical misconduct. Ruttiman says the deaths have been analyzed, and says all of them were clearly unrelated to the vaccine.
