Vaccines inject a weak amount of the pathogen that causes the infection into you. This is not enough to harm you. This causes your bodies lymphocyte white blood cells to produce antibodies that lock onto antigens on the pathogen, marking then out for your phagocyte white blood cells to destroy them.

This means that next time you get infected with the pathogen, your body recognises it quicker so it can produce the antibodies much faster and destroy the pathogen before you express any symptoms.

Vaccines are created by taking a sample of whatever you want to prevent and heating it up just enough to kill it or severely weaken it. When that is injected in a person, their immune system will still fight it like it was alive. Even though it's dead, it's still the virus/bacterium, and your body marks it down as such.

So now here comes the real thing, but your body already knows from the vaccine that this is a very bad thing and needs to be removed. Your immune system promptly does so.

When a person receives a vaccine, the body reacts by making protective substances called "antibodies". The antibodies are the body's defenders because they help to kill off the germs that enter the body. In other words, vaccines expose people safely to germs, so that they can become protected from a disease but not come down with the disease.

The human body has several different types of white blood cells (WBCs) which fight foreign invaders (Antigens) that enter our body. Certain types of WBCs react to specific invaders to produce antibodies that aid in the destruction of these antigens. However, it takes time to produce these antibodies, especially if it is the first time the body has come into contact with a specific antigen.

The Lymphocyte is a WBC that transforms into a B cell. Whenever an antigen enters the body, the B cell proliferates into plasma cells and memory cells. Plasma cells produce the antibodies against a specific antigen. The first time this happens, it takes several days for the antibodies to become numerous enough to do any good. The memory cells are created to prevent this time lag from happening again. They enhance the production of antibodies upon second contact.

Vaccines are a collection of dead or attenuated antigens (foreign invaders) that are introduced into the body so that memory cells are created. If the live antigen enters at a later time, the body now has the ability to rapidly create antibodies. The vaccine does not prevent future infections, it enables your body to kill the foreign invader before it has an effect on your body. Therefore, you won't even know you've been infected.

INFECTIONS


Do vaccines work against viruses and bacteria?

No. Vaccines are not used for treatment. They are used as prevention.


Can vaccines be used to prevent some bacterial infections?

yes, it can help up to a little bit.


How vaccines prevent infection?

Vaccines do not prevent infection. Vaccines prepare the immune system to fight infection by allowing the immune system to produce antibodies to a specific invading organism, kill it, and remember it in the future. In vaccines, this organism is often weakened or dead. If the invading organism is found by the immune system in the future following immunization, the immune system remembers it and produces the specific antibodies needed to kill it quickly.


How are vaccines benificial?

vaccines are beneficial because they help prevent a disease happening to a person in the future by developing anti- bodies in the blood. they help fight the infection better


Do all infections cause disease?

Yes, they both do. The difference is that you can cure diseases from bacteria but not from viruses. You can prevent both kinds with vaccines.


Can vaccines work on viruses?

Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.


What are vaccines made?

Vaccines are made in several ways. However, all vaccines have the same general goal: weaken the virus or bacteria in a way that allows the recipient to develop an immune response without developing any symptoms of infection. Vaccines are made using the same components that are found in the natural virus or bacteria.Vaccines are made of small amount of the bacteria, virus or other antigen and administered to stimulate the immune system to create antibodies to prevent future infections with the disease.Viruses grows in primary cells, or on continuous cell lines

What does vaccine and pathogenic have in common?

Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.
