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.
