Passive Immunity & Acquired Immunity ,
passive acquired
Skin is an example of innate immunity. It serves as a physical barrier that protects the body from pathogens and prevents their entry. Innate immunity is the body's first line of defense, providing immediate, non-specific responses to infections, unlike acquired immunity, which develops over time and targets specific pathogens.
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.
An example of artificially acquired passive immunity is the administration of immunoglobulin therapy. This involves injecting antibodies (such as those found in human serum) into a person to provide immediate but temporary protection against specific infections, such as hepatitis B or rabies, following exposure. Unlike active immunity, this type of immunity does not involve the host's immune system producing its own antibodies.
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.
Receiving antivenom after a snake bite would be an example of passive immunity, where antibodies are transferred from another source (in this case, the antivenom) to provide immediate protection against the venom.
An example of acquired immunity is the immune response generated after receiving a vaccine. When a person is vaccinated, their immune system is exposed to a harmless form of the pathogen, allowing it to produce specific antibodies and memory cells. This prepares the body to recognize and respond more effectively to the actual pathogen in the future, providing long-term protection against diseases such as measles or influenza.
Naturally acquired active immunity means that you have contracted the disease and your body has developed immune defenses against the disease. An example if when a person gets Chickenpox- the body has memory cells which functions to produce an immune response when it recognizes the same virus later on. The immunity for chicken pox is usually lifetime.
