NEW DELHI -- 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.
The country widened the gap between shots from 12 to 16 weeks in order to administer more first doses at a time when supply was limited and infections were surging — a tactic countries like the United Kingdom have used in times of crisis. But it created a lag in getting people fully immunized.
“We would like to see this number go up. Complete coverage is absolutely critical,” Paul said.
For now, the country appears to have enough vaccines to do that — but its supplies will be watched closely since it is a major supplier of the shots globally. When it halted exports in April as cases surged at home, it had a devastating impact on poorer countries that particularly rely on doses from India. Exports resumed earlier this month.
The government is now optimistic that the country’s rising vaccine supply will be enough to cover its international and domestic commitments. Both of the two main suppliers have ramped up production, with the Serum Institute of India now producing around 220 million doses a month and Bharat Biotech about 30 million, Paul said.
Still, experts say the vaccine situation will need constant review. “There can be no written-in-stone rule — if infections rise drastically, they can again stop exports until there’s enough doses,” said K. Srinath Reddy, president of the Public Health Foundation of India.
On Thursday, India confirmed more than 18,400 new cases and 160 deaths — dramatically below the worst days in May when daily fatalities exceeded 4,000. Overall, the country has recorded around 34 million infections and over 450,000 deaths, according to the Health Ministry, though those figures, as elsewhere, are likely undercounts.
Even states where infections were swelling a few weeks ago, such as Kerala along the tropical Malabar coast, have seen a sustained decline.
“There is a sense of comfort that India has suffered the worst of the delta variant, but this must be accompanied with a feeling of caution,” said Reddy. “Even if cases go up, we are unlikely to see the scale of the surge earlier — if that does happen, it would be fairly unexpected.”
India earlier said it aimed to vaccinate all eligible adults by the end of the year, but experts say the current pace of immunizations will need to increase to meet this goal, even though it has already ramped up significantly. Though the campaign began in January, by mid-June, only about 3.5% of the population had been fully vaccinated.
India celebrated the achievement of 1 billion shots with fanfare Thursday — though it's not that surprising since it's the world's second-most populous country. The first country to reach that milestone, China, is the most populous.
Billboards announcing the feat with a photo of Prime Minister Narendra Modi were posted across New Delhi. Outside a local politician’s house in the capital city, residents gathered as sweets were distributed. A song and film to commemorate the moment have been released, and the Indian flag was unfurled at the historic Red Fort in New Delhi.
In recent months, life in India has swung back to normal. Markets buzz with activity, foreign tourists are allowed again after a 19-month hiatus and the country is gearing up to celebrate Diwali, the Hindu festival of lights.
But there are fears this could be a lull before a storm. Even though India may have borne the brunt of the delta variant already, things could escalate quickly if a new variant emerges — either from within the country or outside.
“If the virus becomes different or mutates, it changes the dynamics. This could change everything,” Paul said.
