At present, there are about 10 such vaccines on which the final stage is being tested all over the world. However, the initial results of Pfizer, which is developing the vaccine jointly with Moderna and the German biotech company, have raised hopes among people. In such a situation, let us know about those top-5 vaccines, which are working from China to Britain and by when will they come in the market?

US drug manufacturer Pfizer has prepared this vaccine in collaboration with German pharmaceutical company BioNotech. The results of the third phase of the vaccine have been released by Pfizer. This drug has created great hope among the people. This vaccine has been found to be up to 95 percent effective.
