I was supposed to get a tetanus shot today as I have not had one in about 38 years. My new PCP really wanted me to get one due to the additional protection from the whooping cough. I know it is dangerous for babies to be exposed to the whooping cough.. But I am not around babies and I figure if I cut myself or step on a nail, I can get one then. I clearly remember my shot in 7th grade. I ended up with a red, sore, hot shoulder for several days. Am I being a wimp? When was your last tetanus shot?
