vaccination drive has significantly slowed in recent months due to a shortage of jabs and hesitancy, even as it battled a vicious surge in cases in April and May that overwhelmed the healthcare system in many places.
Case numbers have since fallen sharply and the authorities have again relaxed many restrictions, sparking fears of another wave.
The government had expanded the vaccine rollout to include all adults aged below 45 on May 1, but states and private hospitals had to procure and buy the shots themselves for the younger age group, leading to confusion and shortages.
But New Delhi later changed tack, announcing it would procure 75 percent of vaccine supplies and distribute them to states so that they can inoculate people for free.
