Our deadly second wave of covid has been ebbing for two months, but the number of daily infections continues to stay worryingly high. India reported an average of more than 42,000 daily new cases over the past week, about a tenth of our 6 May peak of over 414,000. While covid fatigue is understandable, such careless crowding could set off a third surge that epidemic experts have warned of. Like our immunity, that varies widely, and moving the needle on this variable of vulnerability is the task of vaccination. Since ring-fences require reliable information, their success would also depend on the accuracy of our approach.
