Tetanus Shot for Adults: What You Need to Know

Question
The pediaticians office just gave my 19 yr old daughter the shot today.  She thought it was the flu vaccine and when she questioned it, realized they had given her a tetanus shot about 6 weeks ago.  Anything we need to worry about having two?

Answer
no need to worry.... will have a sore arm for a few days but having two won't hurt her in any way with her immune system...... tell her to write it on her driver's license, because nobody ever remembers from year to year, so that will be a good place to keep a record.
