Protective Efficacy and Pulmonary Immune Response Following Subcutaneous and Intranasal BCG Administration in Mice

Intradermal injection of antigen can theoretically produce the same antibody response as 10-20% of the volume required for subcutaneous injection. This paper demonstrates equal efficacy of intradermal injection of Fluviral vaccine as compared to subcutaneous injection in an ambulatory geriatric population. There was no difference in adverse reactions between the two groups. A significant portion of both groups did not develop protective HAI antibody level to or more than 1/40.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
