They were interviewed in the New York Times and elsewhere. Epidemiologists are better at judging these things than doctors in the field. Doctors have often been mistaken about the efficacy of a drug. The epidemiologists say the curves of the recent outbreaks indicate the epidemic abated because of natural herd immunity in the hard hit districts. The doctors took antibody tests from a sample of the population. They found that the infection rate was far higher than official statistics showed. It was high enough to achieve local herd immunity. Local herd immunity is why there are multiple waves of an epidemic in different cities over time.
Double-blind tests of ivermectin show either a very small effect, or none at all, so it is not possible it has had a giant effect on the Indian population. The doctors in the field are not more skilled in administering the drug than the doctors doing the double-blind tests. The doctors in the field have described their methods, dosage and so on. Clinical double-blind tests did not replicate their claims. When a drug has a small effect at best, the way ivermectin does, the only way to confirm that effect is with a double blind test.
