The Difference between the New mRNA and a Normal Vaccine

I compare the use of normal and the new mRNA vaccines with each other and what effects they have on the pandemic. The world made a terrible mistake to rely on only one type of vaccine and didn’t calculate the risks doing that. But with the exclusive use of the mRNA vaccine, the population is constantly open for new infections and the chance that the pandemic will be gone is less likely. What is more likely is that the pandemic will rage for many years to come. If they had an alternative, like a normal vaccine, this would not happen.
