Corona pandemic in many countries attacked people more than single phase. Even in India now it is 2nd phase of covid-19 which is more dangerous. Today even India crossed Brazil & America where as not a single country remain aloof from this pandemic which started first from China’s Wuhan city. Since two years people from almost all countries are suffering, dying by which everybody is in panic with a common question, “when corona will pass & no expert, scientist yet able to answer rightly the same. the most important thing is that, WHO’s recommendation are not with some vaccine like covaxin of India, which may pose a barrier for Indians to travel foreign countries. Nobody can ignore India’s own vaccination as it is 2nd most populated country of the Earth. In the way different vaccination cropped up in different countries like China, America, Russia & Canada is somehow or other, is not disciplined. Prior to this, the same opinion has been expressed by WHO’s chief. He told categorically that throughout all the nations of Earth one particular vaccine should have been invented & by that World as a whole would have been able to vaccinate all human race. In case of India, what will happen next, nobody knows. Still covishield & covaxin are two vaccine with which we can meet the challenge undoubtedly.
