Okay, let me start off by saying I'm very clumsy and often bump into things, sometimes causing injury to myself, though nothing serious. However...recently, I've noticed a couple of scratch marks on my body, one of which is on my shoulder. They don't look too bad, but if I keep getting scratch marks on me, the wounds might become infected with bacteria and possibly cause tetanus.
P.S., my last tetanus booster shot was on July 22, 2015, but I don't remember if it was the Td or Tdap vaccine. My previous booster shot before that one was on October 14, 2009.
I´m not sure since I´m not so good at this area
