Scientists need to perform intensive research and study to design a vaccine against particular microbes. This vaccine is based on the fundamental information such as how it infects the human or animal cell and what is the immune reaction of the infected cell. Researchers have developed different types of vaccines such as live attenuated vaccines, subunit vaccines, inactivated vaccines, conjugate vaccines, toxoid vaccines, DNA vaccines, and recombinant vector vaccines.
Recombinant vector vaccines are made through biological preparation that produce active immunity against certain microorganisms in human-beings and animals. They produce antibodies to fight with different types of bacteria and virus. The vaccine enables an antigen T-lymphocyte which in turn generates strong cell in the body that fight against antigen of microbes or virus. This combination of vaccine is effective as it is produced by DNA technology for the prevention of lethal disease. There ... Read more
