Before the advent of biotechnology, the vaccines where made from inactive or dead pathogens of that disease. But now the vaccine is made artificialy using biotechnological processes. Such vaccines used to produce some disease symptoms in some cases. The antigen of the disease is researched upon and its genetic code is found out. A similar antigen is made in the laboratories which is used as a vaccine. Such vaccinrs are more thermostable and remain active for longer duration. Therefore, the vaccines are now safer.
