If you got a tetanus booster at the beginning of a school year and keep on missing the dates to get the second booster can the vaccine hurt you?

Tetanus boosters are good for 10 years.If you go past the 10 year mark,the other booster wont hurt you when you get it.I got a Tetanus shot in 1994 and that is the first one I ever remember having.I felt fine after having it.
