The government on Saturday exempted basic customs duty on import of Covid vaccine, medical-grade oxygen and related equipment to boost domestic availability and make them cheaper amid rising infections across the country. The decision to exempt customs duty was taken at a meeting chaired by Prime Minister Narendra Modi to boost oxygen availability in the country and put highest priority on Covid treatment. Over the past two months, the outbreak in India has exploded, with reports of super spreader gatherings, oxygen and medicine shortages.
