Also known as: vaccines, booster shots, immunizations.
What are vaccinations?
Vaccinations are doses of dead or weakened viruses, bacteria or other organisms that provide the body with protection from developing the illness related to the organism later in life. Many are given early in life to protect children from dangerous illnesses, but others are given annually (such as the flu vaccine) or later in life.
What happens during the procedure?
Vaccines are frequently administered through an injection, through the mouth or via the nose. Some require multiple doses given in intervals.
Is any special preparation needed?
In most cases, no special preparation is needed before administration of a vaccine. Most require that the patient not be sick before administration.
What are the risk factors?
Pain, swelling or redness at the site of the injection are the most common risks. In general, vaccinations are very safe, and the benefits far outweigh the minor risks.
