In photos: COVID vaccinations around the world
Officials are stepping up efforts to reach some of the world's most remote regions in a global vaccination drive, as the world crosses 1 billion total COVID-19 vaccines administered.
The big picture: Most doses have gone to rich countries so far, but President Biden's pledge to soon export 60 million doses could be a global game-changer. The WHO is pushing to increase trust and investment in vaccines during World Immunization Week, which runs until Friday, with the message that "vaccines bring us closer."
