Do you get a tetanus booster shot every 10 years as recommended for adults? Hubby and I have been discussing this. He cut his arm putting up fencing and a couple weeks ago I scratched my arm on barbwire. Both wounds became infected (tea tree oil cleared it up though). We're thinking we should get tetanus shots since we're both so accident prone. I know I haven't had one since 1985-86 and he can't remember the last one he had. What are your thoughts?
