Artificially acquired passive immunity refers to immunity from:
A person acutely suffers from a disease when his immune system is unable to produce antibodies to deal with that particular disease. Hence external immunoglobulins are administered in the form of anti-serum. Anti-serum contains antibodies against that specific disease which is injected intravenously to the patient. This provides artificially acquired passive immunity.
Maternal antibodies (IgG) reach the placenta and enter the child's blood circulation through the umbilical cord. The maternal IgA reaches the child through colostrum/ first breast milk which is natural passive immunity.
In natural active immunity, the immune response is produced when active microorganisms (pathogens) from nature enter the body. The immune system is stimulated, hence the body produces antibodies.
