India's Covid-19 vaccination pace seen dwindling from first day record

India's vaccinations over the next few weeks could fall short of the blistering pace set on the first day of a federal campaign, unless it makes inroads in a vast hinterland and bridges a shortage of doses, experts said on Tuesday.

The 86 lakh doses injected on Monday represented a record two-fold jump as India kicked off free inoculation for all adults, reversing a policy for individual states and hospitals to buy vaccines for those aged 18 to 44.

"This is clearly not sustainable," Chandrakant Lahariya, an expert in public policy and health systems, told Reuters.

"With the currently projected vaccine supply for the next few months, the maximum daily achievable rate is 40 lakh to 50 lakh a day."

The inoculation effort in the world's second most populous nation had covered just about 5.5% of all the 95 crore people eligible, even though India is the world's largest producer of vaccines.

A devastating second wave of infections during April and May overwhelmed medical staff and facilities, killing hundreds of thousands. Images of funeral pyres blazing in car parks and open spaces spurred questions over the chaotic vaccine rollout.

Since May, India has distributed an average of fewer than 30 lakh doses each day, far less than the 1 crore health officials say is crucial to protect the millions vulnerable to new surges.

Particularly in the countryside, where two-thirds of a population of 140 crore lives and the healthcare system is often overstretched, the drive has faltered, experts say.

Maintaining the pace of the vaccination effort will prove particularly challenging when it comes to injecting the younger population in such "underserved" areas, said Delhi-based epidemiologist Rajib Dasgupta.

Widespread vaccine shortages since May have worsened the divide between urban and rural areas, as many younger people in cities turned to private hospitals, paying between $9 and $24 a dose in the rush to protect themselves from the virus.

Such regional gaps in healthcare are exacerbated unless comprehensive data is made available on vaccinations, among others factors, said Bhramar Mukherjee, a professor of epidemiology at the University of Michigan.

Authorities in New Delhi said more than 80 lakh residents had yet to receive a first dose, and added that inoculating all the adults in the capital would take more than a year, at the current pace.

Even as new infections have dropped nationwide to their lowest in more than three months, experts expressed concern over the transmissibility of the variants driving infections in India and spreading worldwide and urged a faster vaccination effort.

Over the past 24 hours India reported 42,640 new infections, its lowest figure since March 23, along with 1,167 deaths.

Its tally of infections now stands at 2.998 crore, with a death toll of 389,302, health ministry data showed.
