Hi, Yesterday I Took My 6 Month Old Daughter To

Hi, yesterday I took my 6 month old daughter to her 6 month appointment. She received one oral vaccination, and 3 other shots. The D-Tap was given twice by accident instead 1 dose of the flu shot. Dr said it should be ok that she received D-Tap twice & to come back in on Monday to get flu shot, (needed for upcoming flight later that week) But I'm still freaking out about the over dosage of a vaccination & I feel very uncomfortable & seeking for further information. My baby's left leg has broken out into a red rash but no temp & she's been in a good mood.
