Biotechnology is a group of technologies that work together with living cells and their molecules to extend life (Keener and Hoban et al., 2014). Today biotechnology can be used in various ways, for example in an industrial context where they use it to create enzymes to synthesize chemical substances, in an environmental context where they use it for the prevention of waste and pollution and finally it can be used in applications medical such as in pharmaceuticals, genetic engineering, DNA fingerprinting and finally it can be used in stem cell therapy (Keener and Hoban et al., 2014). Everyone in today's society depends on and uses biotechnology in one form or another, biotechnology is essential to our health and well-being. Vaccines are also produced using biotechnology in which they consist of three main ways: it helps scientists to separate the pure antigen using specific monoclonal antibodies, it helps in the synthesis of an antigen with the help of a cloned gene and finally it also helps in the synthesis of peptides to be used as vaccines (Alam 2014). A vaccine can protect you from specific diseases that can make you seriously ill or even kill you. Vaccines strengthen your immune system by helping the body create antibodies for a specific disease so that the next time a real infection arises your body will be ready to deal with it. the infection which in turn helps in the resistance of the antibodies. Biotechnology has provided tools to understand virulence, i.e. the ability of a microorganism to cause disease (virulence meaning: Collins English Dictionary 2014) and the functioning of microbial immunogens and, secondly, offers new ways to create vaccines (Fields and Chanock, 1989). first invented by Edward Jenner in 1796 to protect against smallpox, involving...... middle of paper .......• Josefsberg, J.
