When administering a subcutaneous vaccine, what is the recommended angle of injection?

The recommended angle for administering a subcutaneous vaccine is 45 degrees. This angle is conducive to ensuring that the vaccine is delivered into the fatty tissue just beneath the skin while avoiding the deeper layers of muscle. Subcutaneous injections are typically performed in areas with adequate fat, such as the outer triceps area or the abdomen.

Injecting at 45 degrees allows for effective absorption of the vaccine and minimizes the risk of inadvertently hitting a muscle or blood vessel. Choosing the right angle for subcutaneous injections is crucial for maximizing the immunogenic response while ensuring safety and comfort for the patient.
