The conclusion is drawn that each type of vaccine has unique properties that cannot be replaced by others and that it was not easy to determine the best among them.
The use of vaccines to combat disease by humans has been ongoing for centuries and has produced significant results.

This paper have analyzes three main types of vaccines that have been developed and commercialized: DNA vaccines, mRNA vaccines, and inactivated vaccines, to gain insight into the issues associated with vaccines. This paper explained the mechanisms of action and the process of their production, and identified some of their potential advantages and disadvantages. Finally, this study draw the conclusion that each type of vaccine has unique properties that cannot be replaced by others and that it was not easy to determine the best among them.
