Hello Doctor, I have 2 questions 1. Does tetanus overdose cause any side-effects? I was supposed to take tetanus vaccine last month (the one we usually take once in 6 months). I m not sure if I had taken or not. So, I d like to get one more shot.. 2. I got an intradermal rabies vaccine on day 0,3,7,28 (on both deltoids on those 4 days). How long does that effect last? Thanks in advance. Regards, Kowsik
