Do vaccines completely protect you from diseases?
If you get vaccination shots, would you still have a chance to be exposed to a disease? (is the chance great?)

The answer to your question is that vaccines are great, but not 100% effective. What vaccines do is they allow the body to produce antibodies to fight more effective the "thing" in view. The key words are "more effective." For example, according to Center for Disease Control Center the season flu vaccine is only effective within a range of 40-80% depending on the age and overall health of the person. Also with new strains, no one can be certain what the effectiveness will be. The Swine flu is a case in point. See link for the Center for Disease control explanation with charts and statistics.
Nothing works 100% of the time, not even vaccinations. So no, vaccines do not completely protect you from diseases.
There is a chance that you could contract a disease (I don't think you should say "be exposed to" that just means you're around the germs. "Contract" means actually getting the disease, which is what matters.) even after you've been immunized, but the chances are very small.
For example, there were only nine cases of rubella in 2004 in the United States. So of all the people alive in the US in 2004, only nine got the disease even though it used to be a very common disease.
Immunization, also called vaccination, a method of strengthening the body resistance against specific diseases using microorganisms - bacteria or viruses - which have been changed or killed. These microorganisms do not cause disease treated, but stimulates the body's immune system to create a defense mechanism that protects against disease continuously. If the protected person against a particular disease contacts the agent that causes disease, the immune system is able to respond immediately against the disease.
Immunization reduced the amazing number of people dying from a fatal disease. Scientists have discovered two types of immunization: active immunization, ensuring greater period of protection against disease, and passive immunization, ensuring temporary immunization.
In active immunization, some or all micro-organism that causes disease or as a product of the same product is injected into the body to make immune system to resist disease.
Vaccines that produce active immunization are made into several types depending on the type of disease and the body it causes.
Vaccine components are antibodies, substances found in the body that cause disease, so that the immune system recognizes them as foreign. In response to the antibodies, the immune system creates antibodies or other white blood cells called lymphocytes. Immunization mimics real infection, but have little or no risk of infection with the disease.
Passive immunization is the injection of blood from a person or an animal actively immunized.
Some agents in vaccines provide complete protection against the disease throughout life.
Some agents offer partial protection, ie the vaccinee may contact the disease, but to a less severe form.
Vaccines are considered risky for people who have an immune system partially destroyed, such as those infected with the virus that causes immunodeficiency syndrome or AIDS, or those which are chimo therapy for cancer or those awaiting an organ transplant.
Some vaccines need to be repeated at specified intervals. Tetanus injections, for example, are recommended every 10 years throughout life.
no vaccine can save u 100% from the attack of germs. vaccine contains the paralzied or dead germs of the same disease 4 whch it is being used and u r always suseptable to the germs even u r vaccined though chances 2 get infection r very small . u can say its upon God either he wants u 2 b blessed by the advantages of it or not. nice question overall.hv a nice tym friend.
A vaccine is made from weakened virus from that disease. When the vaccine is injected into a person, the person's body starts to make antibodies to fight off the disease. These antibodies will remain in the person's body to fight off the disease if exposed to it at a futher date. Sometimes the vaccine injected is so weak that the body does not make enough antibodies to fight if off if exposed and the person may come down with that disease. Most vaccines are highly effective but not always 100 %. Sometimes when the person is injected with the vaccine, the virus is not weak enough and you will get the disease because your body can't produce enough antibodies to fight it off. An example is that some people come down with influenza when given the flu shot.
