仅凭一家基金会，能否改变人类命运？

Core Viewpoint - The Gates Foundation aims to eradicate tuberculosis (TB) globally within the next 20 years, emphasizing the need for increased investment in research and development for diseases primarily affecting impoverished nations [3][4][5]. Group 1: Tuberculosis and Global Health Initiatives - Despite being rare in wealthy countries, TB remains prevalent in parts of South Africa, with the Gates Foundation supporting clinical trials for a new vaccine that could potentially eradicate the disease [2][19]. - Bill Gates highlighted the tragic reality that TB still caused 1.25 million deaths in 2023, attributing the lack of attention to the disease's prevalence in poor countries [3][4]. - The foundation plans to invest $200 billion over the next 20 years to significantly reduce mortality rates from various diseases, including TB, and to enhance health innovations [3][4].
