A recent study has shown that the impact of Omicron in India was less, as compared to countries like the US and the UK, because of the presence of hybrid immunity among its population.
Hybrid immunity is the immunity generated when a person with prior infection receives a vaccine
This hybrid immunity wall is the reason India had a relatively minor third wave
As more than 70% of Indians were infected with Delta during the second wave and India has vaccinated 95% of eligible population, at least with one dose, so close to three-fourths of India's population has hybrid immunity. This hybrid immunity wall is the reason India had a relatively minor third wave.
