what is the difference between a shot and an injection
Injection (medicine) Injection (often referred to as a "shot" in US English, or a "jab" in UK English) is the act of putting a liquid, especially a drug, into a person's body using a needle (usually a hypodermic needle) and a syringe.[1] Injection is a technique for delivering drugs by parenteral administration, that is, administration via a route other than through the digestive tract. Parenteral injection includes subcutaneous, intramuscular, intravenous, intraperitoneal, intracardiac, intraarticular and intracavernous injection.
