At least half of Mumbai's under-18s have been exposed to Covid-19 and have antibodies against it, raising some hopes for levels of protection in that age group, Reuters quotes a senior official as saying.
The figures came from a government survey in India's financial capital conducted from April to mid-June, when the country was in the middle of a devastating second wave of the disease that left thousands dead.
Some experts have warned that a potential third wave could hit children, and Mumbai has joined other cities in building huge paediatric wards in preparation.
