WHAT IS DNA VACCINE

In this technique, immune proteins are developed using the DNA of the body. This protein prevents virus infection and protects the cells of the body from corona virus infection. The whole world has become a fan of the indigenous vaccine made on DNA technology against Corona. Zydus Cadila's vaccine Zykov-D is the first DNA vaccine made not only against corona but against any disease in the world. Scientists believe that this vaccine based on DNA technology can pave the way for a vaccine for a complex disease like cancer in the future. The Drug Controller General of India last month allowed its emergency use after meeting its effectiveness and safety standards against Corona. According to him, efforts to make DNA vaccine for various diseases were going on all over the world since 1990, but for the first time India's Zydus Cadila has got success. That is why this achievement is special. D has been 67 percent effective in preventing corona infection. It has been proved that it is actually capable of preventing many diseases. DNA vaccine is termed better than RNA vaccine. The biggest feature of DNA vaccine is that it remains stable at normal temperature, whereas RNA vaccine has to be kept in temperature from -20 to -80 degree. The RNA vaccine has been found to be more than 90 percent effective against the corona, but their trial took place before the arrival of the delta variant of the corona, during which it was relatively less infectious, while Jaykov-D has proved its effectiveness on the infectious delta variant. A vaccine based on DNA technology can use a complex protein or a combination of several proteins. According to Nature, work is currently underway on about a dozen DNA vaccines against Corona all over the world. Out of which the vaccines of Osaka University of Japan and Inivio & Partners of America are in the second and third phases of clinical trials. While Zydus Cadila's Jaycov-D will join India's vaccination campaign this month.
