How does the flu vaccine work?

Answer 1

In simple terms you are given a very tiny dose of the virus, dead in this case, your body then develops antibodies to that virus, remember it only take a tiny amount, not enough to cause illness. When you do encounter the flu you are already immune and will not get sick since you already have antibodies for it. Each year the flu vaccine is developed to target what they think will be the strain you need protected from and it only protects you from that, not all flu viruses so you still do have the potential to get the flu.

Answer 2

The same principle as all vaccines: Vaccination is the process of administering weakened or dead pathogens to a healthy person or animal, with the intent of conferring immunity against a targeted form of a related disease agent. It succeeded and is distinct from inoculation.

The term was coined by Edward Jenner and adapted by Louis Pasteur for his pioneering work in vaccination. Vaccination (Latin: vacca—cow) is so named because the first vaccine was derived from a virus affecting cows: the cowpox virus, a relatively benign virus that provides a degree of immunity to smallpox, a contagious and deadly disease. In common speech, 'vaccination' and 'immunization' generally have the same colloquial meaning.

Vaccination efforts have been met with some resistance since its inception. Early success and compulsion brought widespread acceptance and mass vaccination campaigns were undertaken which have greatly reduced the incidence of many diseases in many areas. The eradication of smallpox, which was last seen in a natural case in 1977, is considered the most spectacular success of vaccination. Currently some people assert that childhood vaccination causes some autoimmune disease and autism. Scientific studies have not demonstrated a link, however, the assertion found space in a United States House of Representatives report in 2003 which included the suggestion that mercury derivatives in vaccines might have been a cause of autism

Answer 3

Flu vaccine works by actually making you sick. This triggers your immune system to adapt to that small exposure. Now your white blood cells are prepared for that certain virus. Flu vaccines like all of them just expose you to tolerable amounts of a poison, virus, etc.

Answer 4

All vaccines work in the same way. The injection you receive is a strain of the disease that has alreadsy been weakened by drugs. these less powerful viruses are injected into your body, thus creating the army of white blood cells that will fight the disease. they will then be programmed into your brain when such a virus might invade your body so the brain can tell your bone marrow to produce the right cells to fight the invading "alien" in your body.

Answer 5

a vaccine is itself a flu virus but not harmful
it makes the immune system familiar with that virus and in turn the body gets prepared to fight for the virus and it enters the body

its similar to a war


for example
if the soldiers or a country are informed about how would the enemy attack them and with what weapons they would enter, then the army being attacked would get prepared accordingly

Answer 6

buy giving you a live strain of flu and your imune system kills it, there fore once the flu starts doing the rounds you wont catch the flu as your body has already built a defence against it from the vaccine

Answer 7

It doesn't work. Different strains of the virus appear every year. Therefore, the vaccine you will be given this year is more than likely last years strain. No-one can tell which strain will be about this year. It makes no odds wether you have the shot or not.

Answer 8

It gives you a small amount of the flu virus so that your body will make antibodies to fight the flu.

Answer 9

same as any vaccine !

it gives you a small dose of flu! your body creates the correct antibody! and then when you get it your body already has the means to get yourself better!

its a good theory but csn mske you pretty ill before your natural defences deal with it!

Answer 10

They shoot dead or weakened flu bugs into your body and your body manufactures stuff to fight those flu bugs.
