The word 'injection' refers to a shot or medicine that is given to a person with a needle. It is used in medical contexts where a person needs a medication or vaccine introduced into their body quickly and directly. Injections are often used for vaccinations, insulin for diabetes, pain medication, and antibiotics. They can be administered by healthcare professionals or by people themselves after being trained by healthcare professionals. It is important to take great care when using needles to avoid injury or infection.
