Artificially acquired active immunity.
active acquired immunity and passive acquired immunity
Active immunity to a disease is acquired either through getting the disease or being vaccinated for it.
Naturally acquired active immunity
Tetanus shots protect against diphtheria, tetanus, and pertussis.
The response to infections is active or cellular immunity. Acquired immunity
There is innate immunity (that you are born with) and acquired immunity. Acquired immunity you get when you are vaccinated or you get the disease and fight it off. The best example is that of what we call common colds. There are about 100 different viruses that cause them. This is one reason that babies and young children seem to be always be coming down with one or getting over one.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.
Naturally acquired active immunity
active
Active immunity is long term protection that generally lasts 20-30 years and passive immunity is immediate protection. there are two forms, naturally acquired and artificially acquired. in active immunity the naturally acquired immunity is when you suffer from the disease then recover again. the artificially acquired way is by getting a vaccination. in passive immunity, the naturally acquired way is to receive antibodies from mother in pregnancy and breastfeeding, the artificial way is to have antibodies injected in a serum for immediate response for example when you have been bitten by a poisonous animal. note they are not vaccinated.
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
