Altruism Scepticism and collective decision-making in foreign-born U.S. residents in a tuberculosis vaccine trial

摘要

BackgroundThe current vaccine against tuberculosis, BCG, is effective when given in most TB-endemic countries at birth but has diminished efficacy against pulmonary TB after 15–20 years. As a result, new booster vaccines for adolescents and adults are being developed to realize the World Health Organization target of global elimination of TB by 2035. Multiple TB candidates thus are in active clinical development.
