Antibodies
Freaking awesome bodies!! Antibodies!!
They look for the bodies antibodies that fight HIV infection to tell if a person is infected with the virus.
vaccine
Cowpox was a less harmful version of smallpox. So their bodies created antibodies for the cowpox which in turn could kill the smallpox cells.
Anti bodies they protect our bodies from diseases that's why we get vaccinated ,, To make Anti bodies for the disease that we were injected for :) hope that helps
passive immunity is short term it could either be from a mom giving the antibodies from her blood to the baby in her womb, and when the baby gets out, it still has some of the anitbodies to protect it (for a couple days/ months/ years) or antibodies are injected into a person (this is not a vaccine) to help cure the illness (rabies is an example of a disease where people inject the antibodies)
People with AB blood are universal recipients, people with 0 negative blood are universal donors.
B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies.
Yes, white blood cells, specifically B cells, produce antibodies in response to antigens present on injected microorganisms. When these antigens are recognized, B cells are activated and differentiate into plasma cells that secrete specific antibodies designed to neutralize or mark the microorganisms for destruction. This immune response is a crucial part of the body's defense against infections.
If a person's immune system is producing antibodies against a specific antigen, then that person has a positive or active immunity toward that antigen. If a person has merely been injected with antibodies but does not produce them, that is a passive immunity.
This is the concept of immunization, the immune system identifies the "germ" as an intruder and develops antibodies to fight it.
