Having had rabies shots, tetanus shots, and human immunoglobulin shots, for me, at 235#, it was 4 human immunoglobulin shots (one in each thigh and one in each butt cheek), one tetanus shot in the arm, and a series of 5 rabies shots in the arm spaced out several days apart. So 10 total over 3 weeks.
Unless they were spreading the human immunoglobulin shots around the bites, which I was told they do. Since mine were precautionary with no visible bite marks, they just shot my legs and butt.
The immunoglobulin stuff is really thick, and they used a huge needle. And the dosage was based on body weight. So big guy got the big dosage. Ouch!
