India gave out a record 8.3 million vaccine doses on Monday under a federal campaign to inoculate all adults for free after weeks of criticism that a chaotic rollout had worsened a second wave that killed hundreds of thousands.

Earlier this month, Prime Minister Narendra Modi said the government would buy 75% of all vaccines from drug makers and distribute them for free to states, which along with private hospitals had earlier been buying shots for people aged 18-45.
