Help Doctor, My husband was bitten by dog on the back of his thighs yesterday night around 9.30pm.it was just a superficial injury and not a deep bite at all,no blood,just I could see a red dot and slight swelling in the spot,he was experiencing pain only when pressed on the spot.he immediately washed it and had a tetanus injection. But we were worried and he took first dose of rabis injection today only in the evening around 7.00pm.I am worried of it is too late to start the course?pl tell me..
