From the U.S. State Department:
New foreign assistance funding commitments continue to bolster the unparalleled global leadership of the United States in response to COVID-19. The U.S. Government (USG) has allocated $20.5 billion to benefit the international response, including commitments for the development of vaccines and therapeutics, preparedness efforts, and foreign assistance. We continue to ensure that the substantial U.S. funding and scientific efforts on this front remain a central and coordinated part of the worldwide effort against this deadly virus. Importantly, our global efforts in the face of COVID-19 build upon decades of U.S. investment in life-saving health and humanitarian assistance. We are achieving real results, helping nations around the world respond to COVID-19 and thereby protecting the homeland.
