Welcome to icliniq.com. I am sorry for the dog bite. But, I am glad that you have taken the correct schedule of vaccines till now. Basically there are two types of anti rabies vaccines. 1. Neural tissue vaccine. 2. Tissue culture vaccine. Of these neural tissue vaccines is given in the anterior abdominal wall around the umbilicus for 14 days. Beta-Propiolactone belongs to this category. The tissue culture vaccine are given in the deltoid, outer aspect of your arm, in the regimental badge area on 0, 3, 7, 14 and 28 days. It is not common for them to give beta propiolactone (BPL) vaccine in your arms on 0, 3 and 7 days. If you have got your shots in your arm, then it is tissue culture vaccine. There are five types of tissue culture vaccines (TCV). 1. HDCV - human diploid cell culture rabies vaccine, the most expensive TCV per dose. 2. Rabipur (PCEC - purified chick embryo cell vaccine). 3. Verorab (PVRV - purified Vero cell rabies vaccine), dose of 0.5 mL. 4. Verovax-R (PVRV), dose of 0.5 mL. 5. Abhayrab (PVRV). The good news is that All TCVs that is HDCV, PVRV AND PCEC are freely interchangeable. So, if you had got your previous three injections in your arm, then,please go and get two more injections of tissue culture vaccine on day 14 and day 28 in private.
