Hello There, Firstly, I Just Received A Rabies Vaccination, My

Hello there, firstly, I just received a rabies vaccination, my first shot was free 24 hours of a possible exposure, it was a slight scratch no blood and I do not think the skin was broken but could not be sure. And secondly is it okay I drink during the vaccine process? Also I have been vaccinated before 8 years ago, however explaining this to the nurse was very difficult so they put me on the 5 shot course will this matter?

Thank you

Matt
