My Daughter Just Got A Tdap Vaccination At Kaiser. It

My daughter just got a tdap vaccination at Kaiser. It said on her kaiser record that it was due. But she had gotten some vaccines at her university's health clinic. I am not sure kaiser had the record of the shots she got at her university. I worry that it might be harmful to have gotten the vaccine again if she had already gotten it at the university. Could it be harmful to her if she had already gotten it?
