There is no doubt that the current pandemic required one central agency to control and monitor the same. The present status can only be attributed to the WHO, which has at its disposal a band of the best scientists from all over the world who worked relentlessly. They took all aspects, even economics, into account. Their objective was to break the transmission and they came up with: keep one-metre distance, wear masks, wash hands frequently, avoid crowded places, sneeze in elbow or tissues. Note: all must be done simultaneously. When the transmission is broken you will have protected others and yourself. Wearing masks alone does not protect you, but when two people at one metre distance wear WHO recommended three-layered cloth masks, the efficacy of the mask is 91 per cent. The vaccines in India have an efficacy of 70 per cent. Elderly and those with comorbidity must use N95 masks. Theory alone cannot comprehend all aspects as found in the field. Listen to the experts working in the field, they are not elected people. Protect others and you will be protected. Remember, chickens always come home to roost.
