India was one of the hardest hit countries during the first two waves of Covid. Millions have been affected and more than 530,000 people have died, according to official figures.
But experts believe the true number of Covid deaths could be much higher because many of the cases in which people died were not tested or not reported in official numbers.
The government was heavily criticized for its poor preparation during the second wave in the summer of 2021, when many people died due to a lack of oxygen and vital medicines.
