In an interview to CNBC-TV18, Dr NK Arora said, “The proportion of Omicron is rapidly increasing in metro cities. In coming weeks we are going to see a large number of cases and most of these are going to be Omicron.”“The vaccine escape capability of Omicron is very high. So what value a booster will do is still being evaluated. However, our primary task is that everybody should get two doses because it has been seen that all those who have received primary doses, the risk of severity, hospitalisation and death is much less.” he added.
