In January, Bloomberg reported that vaccine refusal rather than production was the problem in India. The claim was that Indian pharma could make 500 million doses a month, but the Modi government was offering it to other countries because Indian medical personnel were refusing the vaccine over safety concerns.
Although the government pushed hard to vaccinate, the pleas fell on deaf ears. A more longstanding problem was low levels of mask compliance, as this article from October 2020 reports.
My impression is that the recent surge of cases has changed views in India. A concern, however, is that mutations have proliferated.
Mutations to the virus occur all the time, but most of them are clinically insignificant. Still, keeping the number of transmissions low is important because the more transmissions, the more mutations, and the greater the chance of a mutation that isn't blocked by the vaccine.
I've never heard the elevated risk of vaccine-resistant mutations mentioned by those who regard mask-wearing and vaccination as a simple matter of personal choice. The decision to go unmasked, undistanced and unvaccinated jeopardizes everyone's safety, including those who have been vaccinated.
