Vaccines. write your opinion about it in 350 words
The body’s immune system helps protect against pathogens that cause infection. Most of the time, it’s an efficient system. It either keeps microorganisms out or tracks them down and gets rid of them. However, some pathogens can overwhelm the immune system. When this happens, it can cause serious illness.
The pathogens most likely to cause problems are the ones the body doesn’t recognize. Vaccination is a way to “teach” the immune system how to recognize and eliminate an organism. That way, your body is prepared if you’re ever exposed.
A healthy immune system defends against invaders. The immune system is composed of several types of cells. These cells defend against and remove harmful pathogens. However, they have to recognize that an invader is dangerous.
Vaccination teaches the body to recognize new diseases. It stimulates the body to make antibodies against antigens of pathogens. It also primes immune cells to remember the types of antigens that cause infection. That allows for a faster response to the disease in the future.
When the body responds to the vaccine, it builds an adaptive immune response. This helps equip the body to fight off an actual infection.
Vaccines are usually given by injection. Most vaccines contain two parts. The first is the antigen. This is the piece of the disease your body must learn to recognize. The second is the adjuvant.
The adjuvant sends a danger signal to your body. It helps your immune system to respond more strongly against the antigen as an infection. This helps you develop immunity.
