Where is smallpox vaccination given?

• A. In the gluteal region
• B. Over the insertion of the deltoid muscle
• C. In the upper arm near bicep
• D. In the thigh

Answer: (B)

The vaccination is given in the upper arm, specifically over the deltoid region near where the deltoid muscle inserts. This location is chosen because the skin here is accessible and shallow, allowing the vaccine to be delivered into the superficial layers to produce the characteristic local reaction that confirms vaccination. It keeps the injection away from deeper muscle tissue and is easy to monitor for the vaccine scar.
