Step 1: Cell culture rabies vaccine can be given by two routes, intramuscular or intradermal, but never into the gluteal region because absorption there is poor and antibody response is unreliable.
Step 2: For the intramuscular route the preferred site is the deltoid muscle. In children under 2 years of age the anterolateral thigh is used. The intradermal route is also given over the deltoid or thigh.
Step 3: So whether the route is intramuscular or intradermal, the deltoid is the standard recommended site. Subcutaneous and anterior abdominal wall are not used, and the gluteus is specifically avoided.
Step 4: The correct answer is option 3, Deltoid.
