The development of the Vaccine is usually done by the researchers in the fields such as cellular or molecular biology, chemistry, biochemistry, or microbiology. Now Biotechnology involves more on the production part of the drug and how to optimize the vaccine for the availability of the beneficiaries.

Some of the important subject topics which really influences the preparation of vaccines from the field of Biotechnology are as follows:

• Recombinant DNA Technology
• Model Organisms in Human Genome Project
• Medical Biotechnology
• Principles of Bacteriology and Virology
• Microbial Genetics
• Vaccine biotechnology

So there are no so called a perfect field which involves vaccine development but its actually an Interdisciplinary field where a lot of different field experts works together to give an output.
