Vaccination is when a virus, or bacteria, is deliberately administered to you (usually by injection) so that your immune system can prepare to fight a future infection.
Vaccines. A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. Vaccines create immunity that protects you from an infection without causing the suffering of the disease itself. Sometimes vaccines are called immunizations, needles or shots. Here's how vaccines work: 1  Most vaccines contain a little bit of a disease germ that is weak or dead. 2  Vaccines do NOT contain the type of germ that makes you sick. 3  Some vaccines do not contain any germs. Vaccination: Injection of a killed microbe in order to stimulate the immune system against the microbe, thereby preventing disease. Vaccinations, or immunizations, work by stimulating the immune system, the natural disease-fighting system of the body. 1 Most vaccines contain a little bit of a disease germ that is weak or dead. 2  Vaccines do NOT contain the type of germ that makes you sick. 3  Some vaccines do not contain any germs. 4  Having this little bit of the germ inside your body makes your body's defence system build antibodies to fight off this kind of germ. MyNPS Search. Vaccination is when a virus, or bacteria, is deliberately administered to you (usually by injection) so that your immune system can prepare to fight a future infection. Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection.
