What is the standard route of administration for most vaccines?

• A. Oral ingestion
• B. Subcutaneous injection
• C. Intramuscular injection
• D. Intravenous injection

Answer: (C)

The standard route of administration for most vaccines is intramuscular injection. This method is preferred because it allows the vaccine to enter the muscle tissue, where it can be rapidly absorbed into the bloodstream, leading to a quicker immune response. The intramuscular route also allows for the injection of a larger volume of the vaccine compared to other methods, which is important for many vaccines that require a specific dose to be effective. Additionally, administering vaccines intramuscularly can enhance the immune response by efficiently targeting immune cells that reside in the muscle. While other routes like subcutaneous or oral ingestion are used for specific vaccines, the intramuscular route remains the most widely employed for the majority, particularly for vaccines like those for influenza and tetanus.
