Injection with a syringe

An injection (often called 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.
