Injection

An injection, also known as a shot, is putting liquid into the body, usually with a needle and a syringe. There are many different kinds of injections, such as:
 Intradermal (just under the top layer of the skin)
 Subcutaneous (into the fat layer under the skin)
 Intramuscular (into a muscle)
 Intravenous (into a vein) 
 Intraosseous (into a bone)
 Intraperitoneal (into the abdominal cavity)

Injections can be used to prevent illness or to give medicine.

Injections that prevent illness put a dead or weakened version of the virus they want to prevent into the body. The body then 'remembers' the virus to make future encounters of the virus easier to manage.
