Work on building permanent immunity: Baba Ramdev

''We should not say in the misconception that since vaccine is here now so we can stay at peace and stop making efforts. One should not give up on Yoga and continue to build immuity. People are dying from other dieases too. Acquired immunity works only for a specific time but permanent immunity works for a longer time'', says Yog Guru Baba Ramdev to ABP News.
