I have been on an anti rabies course of 0,3,7,14,28 , I had taken the the first 3 doses correctly , now since I had to move to hyderabad I had packed the rest of the rabipur injections and kept it at a friends place , when I went to take the injection on the 14 th day , I saw the fridge was off , now I searched for other shops for rabipur injection but they didn't have it so I was forced to take the injection which was not kept at required temperature for 4 days. What should I do regarding the 4 dose of the 5 dose course.
