What are natural active immunization and artificial active immunization?

1 year ago

Natural active immunization is that in which a previous natural infection induces the primary immune response, specific memory cells are produced and the individual becomes immune to new infections with the antigen. This is what happens in diseases that affect people only once in life, like mumps and chickenpox.

Artificial active immunization is that in which the primary immune response is caused by the inoculation into an individual of specially prepared antigens. This is the case with vaccines.
