The U.S. government spent more than $18 billion last year funding drugmakers to make a Covid vaccine, an effort that lead to at least five highly effective shots in record time. Now it’s pouring more than $3 billion on a neglected area of research: developing pills to fight the virus early in the course of infection, potentially saving many lives in the years to come.

The Indian authorities launched an investigation after an internal government report concluded that some private agencies responsible for coronavirus testing on pilgrims at a sprawling Hindu festival forged at least 100,000 results.

The festival, Kumbh Mela, which ran throughout April, is widely believed to be responsible for a coronavirus surge in many parts of India, as the pilgrims returning from the festival tested positive days after returning to their villages.

The festival drew millions of faithful to the town of Haridwar on the banks of the river Ganges in the northern state of Uttarakhand.
