"It's outrageous ethically, morally, scientifically," said Maria Van Kerkhove, an epidemiologist with the World Health Organization, on global vaccine inequities. In some countries with high vaccination rates - including the United States, Britain and Israel - coronavirus numbers are decreasing or plateauing.

Countries in the Caribbean - which consider themselves a "third border" with the United States - have expressed particular frustration with Washington. "But from the United States, disappointedly, we have not had one dose of vaccines," he said.
