Which combination of vaccine, route, and site for administration is correct?

The combination of the Zoster vaccine administered subcutaneously in the fatty tissue over the triceps is correct because the Zoster vaccine is indicated for prevention of herpes zoster (shingles) and is specifically recommended to be given either intramuscularly or subcutaneously, with subcutaneous administration being an acceptable option in certain settings. The triceps area represents an appropriate injection site for subcutaneous administration due to its accessibility and sufficient adipose tissue, ensuring proper delivery of the vaccine.

In contrast, while the Zoster vaccine can be administered via the intramuscular route, it is not typically done in the fatty tissue over the triceps, as this area should primarily be used for subcutaneous administration. Other vaccines, such as the influenza vaccine and meningococcal vaccine, typically follow different administration guidelines and site preferences, which do not align with the provided options in those other choices.
