India celebrates 1B vaccine doses, hopes to speed 2nd shots

India celebrated giving its billionth COVID-19 vaccine dose on Thursday, a hopeful milestone for the South Asian country where the delta variant fueled a crushing surge earlier this year and missteps initially held back its inoculation campaign. About half of India’s nearly 1.4 billion people have received at least one dose while around 20% are fully immunized, according to Our World in Data. Many of those shots have come in just the past couple of months, after the rollout languished in the first half of the year amid vaccine shortages and problems with the system for rolling them out.
