Acquired or adaptive immunity only develops after there has been contact with a particular antigen. An individual is said to be immune to a particular pathogen when it may be introduced into the body, without causing illness. In contrast to innate immunity, the immune system is changed as a result of exposure to a particular antigen.
Acquired immunity is specific to a particular antigen. For example, previous exposure to the measles virus will have allowed the immune system to adapt, generating immunity to any future measles infection. However, because the response is specific, the individual may still suffer from mumps, influenza, or indeed any other antigenic organism it has not previously been exposed to.
Antigens (antibody generators)
An antigen is anything the immune system recognises as being foreign. When detected, antigens generate an immune response in the body. It is antigens which stimulate the production of ...

I was 13-14 when I watched this movie. It's a long movie if I recall it correctly. I was so moved by it's theme, so I watched it all. I had strong feelings of sadness and sympathy towards little robot David that wanted to be a real child and to have a mom to love him. And that little bear ... I cried during some scenes. I don't ...
World Science Federation - Greatest Mysteries of Gravity | Brian Greene & Kip Thorne
Nobel laureate Kip Thorne joins Brian Greene to trace a story that runs from the trenches of World War I to the rise of gravitational-wave astronomy—a journey that eventually carried black holes to Hollywood in Interstellar through Thorne’s work with Christopher Nolan.
He revisits the improbable path from Einstein’s equations to the moment LIGO—an experiment he helped imagine and that contributed to his Nobel Prize—captured the sound of two black holes colliding more than a billion light-years away. Along the way, he explores puzzles that stymied generations: the nature of horizons and singularities, the mathematical insights of Schwarzschild and Penrose, and the profound divide between what an outside observer sees and what a falling observer experiences.
The conversation also turns to the human side of deep...
