Live-Attenuated and Inactivated DNA Vaccines

An immunizing agent usually contains AN agent that resembles a disease-causing organism and is commonly made of weakened or killed styles of the bug, its toxins, or one in every of its surface proteins. An attenuated or a live vaccine is a type of vaccine that is created by reducing the virulence of a pathogen that is the virus is still viable. Attenuation is a process where a infectious agent is taken and it is altered in a way so that it becomes harmless or less virulent.

These vaccines distinction to those created by "killing" the virus. An inactivated vaccine is a type of vaccine that is made up of virus particles, bacteria, or other pathogens that have been grown in culture and then lose disease producing capacity
