What is meant by "route of administration"?

The term "route of administration" specifically refers to the path or pathway by which a drug or vaccine is delivered into the body. This can include various methods such as oral, intravenous, intramuscular, subcutaneous, and inhalation, among others. Each route can affect the onset of action, intensity of effect, and potential side effects. Understanding the route of administration is crucial for ensuring the effective delivery of vaccines, as it influences how the body absorbs and responds to the medication.

The other choices do not capture the essence of the term. Securing vaccines in a pharmacy relates to inventory management rather than the method of drug delivery. The timeline for administering doses pertains to scheduling rather than the method of administration itself. Record keeping processes involve documentation practices that track vaccinations, which is important but not what is meant by the route of administration. Thus, the focus on how a drug interacts with the body through its delivery method makes the second option the correct choice.
