Why is that when the doctor gives you a shot they are actually injecting you with the disease?


Answer:
Your premise is incorrect, based on poor terminology.The purpose of a vaccine is to expose your immune system to the signs of disease organisms (viruses or bacteria) so that it is primed to fight them.聽 Ideally, on an exposure to the real thing it will fight it off before it gets far enough to make you sick.The "signs" of the disease organisms are molecules, mostly from its surface.聽 Exposing yourself to these molecules in the right form will get your immune system to react to them quickly if it sees them again.聽 These molecules can come in the form of individual surface pieces (bits of the disease bug), whole killed disease bugs or even live "attenuated" bugs.聽 Both the smallpox vaccine and the oral polio vaccine are live "attenuated" organisms; they have been grown in other animals (cows or chicken eggs) so long they are poorly adapted to humans, and while they will cause a small infection they only rarely cause serious illness.聽 The organisms still bear most of the surface signs of the disease-causing variants, and immunity to either gives immunity to both.HTH.
So your body will build up immunity to it.
it is a very small dosage of the disease the body can than start to build an immunity to it don't worry its very very rare to contract the disease from the shot.
They give you the disease in low doses so that your body can build up an immunity. It trains your immune system to recognize certain diseases so that you are better able to defend yourself. It's much easier to stay healthy when your body can identify the enemy. This is also why most doctors advocate just getting the flu when you are still young. Your body is able to build up its defense system naturally instead of having to rely on the aid of shots and medications. But certain diseases, the more serious ones, are controlled through vaccinations.
They inject the disease into your body so your body knows what it is and can detect it incase you find it. When they inject it into you, the disease is dead. Your body will notice that it isn't part of the body and attack it. Then if you catch the live version of it your body will detect it instantly and be able to destroy it.Hope that helped =D
Body builds up immunity to infections. This process takes weeks to months. Body suffers from infection and some infections are fatal. A preventive shot 1)Gives the mildest form of infection which involves no suffering 2)Supplies ready made antobodies to neutralise infections and 3)Gives no infection (dead virus or bacteria) but help build up immunity.
first you are not being given a disease it is inactivated or attenuated (dead or alive) form of the virus that you are being protected against, it does cause your body to produce antibodies to the virus , so when you are introduced to it again your body can quickly generate antibodies to fight off the virus. think of chicken pox, it is said that you can only get them once this is because your body has made the antibody to fight it in the past and has kept it for use in the future. once your body makes the antigen it will be able to acsess it for the rest of your life unless you get an autoimmue disorder like HIV then your immune system will become too weak.
The only time you are injected with the disease is when you receive vacinations. Then the amounts are very small, and you can develop some minor symptoms. Other shots that the doctors will give you can be antibiotics, cortisone, pain medication, or any other number of things.Just because you get a shot does not mean that you are getting a dose of a disease.
Doctor don't want you to suffer from disease that why they immunise before
Now you can classify vaccines into two groups
Live vaccines
Dead vaccines
In live vaccines the microbes are attenuated so that they give you immunity but they can not produce disease in you
in dead vaccines only immunity develops
if you get fever other reactions following vaccination it is because of body reaction to vaccine. Now don't read this as disease
there are drugs which have side effects that is different story
Now I f you are asking about homoeopathy I don't know much the basic concept of homoeopathy is give compound which produce same symptom I really don't how it really cures from disease
