Abstract
Currently, the development of new vaccine technologies for the treatment of
diseases is vital. The use of biotechnology in the application of viruses for the
development of vaccines is a relatively new research platform. Viruses have become an
important tool in biotechnology, and they are being used in the development of
vaccines and anticancer drugs. Some of the viral vectors commonly used to develop
vaccines are adenoviruses, adeno-associated viruses, herpes simplex viruses,
retroviruses and lentiviruses, among others. Viral vectors have been used as vaccines
against a variety of infectious diseases, such as COVID-19, influenza, HIV and
malaria. Viruses have also been used to target drugs to cancer cells by using engineered
viral vectors that can selectively target and infect cancer cells. In this way, viral vectors
can also be used to deliver antitumor drugs. This will selectively target cancer cells.
Thus, vectors can be used to deliver therapeutic drugs directly to the tumor, resulting in
reduced side effects and improved efficacy.
