Professor Raghavan said that let us know what kind of vaccines can be made – 1. Only when you inject the genetic material of the mRNA vaccine virus. 2. The standard vaccine, which is made with a weak version of the virus, does not spread the disease. 3. The vaccine is made by applying the protein coding of the corona virus to the backbone of another virus. 4. Protein of the virus is made in the lab and it is applied with any other stemulus. Everybody is trying to make these four types of vaccines.
He said that it usually takes 10 to 15 years to make a vaccine and their cost comes from 200 million to 300 million dollars. As Kovid-19 aims to develop the vaccine in a year, the expenditure may increase by a hundredfold, ie from 20 billion to 30 billion dollars.
