"A recent risk assessment of the situation in India conducted by WHO found that resurgence and acceleration of COVID-19 transmission in India had several potential contributing factors, including increase in the proportion of cases of SARS-CoV-2 variants with potentially increased transmissibility; several religious and political mass gathering events which increased social mixing; and, under use of and reduced adherence to public health and social measures. The exact contributions of these each of these factors on increased transmission in India are not well understood," it said.

The results show they induced strong antibody and T-cell immune responses for up to 56 days after they were given. T-cells are crucial for maintaining protection against the virus for years.
... 'Or any country which has reasonable vaccine coverage.' 'The emergence of Omicron clearly proves that if we allow a virus to circulate in an unvaccinated population, it would take a form which could be a Variant of Concern, or a new variant.'
