IMMUNE SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Vaccines are designed by scientists to iniciate a weak primary response by our immune systems. They are able to produce a protein that resembles the shape of an ____ on the surface of the pathogen.
A
antigen
B
antibody
C
ion channel
D
phospholipid
Explanation: 

Detailed explanation-1: -When a person gets a vaccine, their immune system recognises the antigen as foreign. This activates the immune cells so that they kill the disease-causing virus or bacterium and make antibodies against it.

Detailed explanation-2: -Vaccines induce antibodies. The adaptive immune response is mediated by B cells that produce antibodies (humoral immunity) and by T cells (cellular immunity).

Detailed explanation-3: -Toxoid vaccines use a toxin (harmful product) made by the germ that causes a disease. They create immunity to the parts of the germ that cause a disease instead of the germ itself. That means the immune response is targeted to the toxin instead of the whole germ.

Detailed explanation-4: -It begins releasing antibodies to fight the germ-think of antibodies as soldiers designed to fight off the specific germ you have. This process can take a few days. The antibodies work to attack, weaken, and destroy the germ. Afterwards, your immune system remembers the germ.
