call the office when they open. i am sure they have a protocol for missed shots. since i do not know your daughter's medical history or what type of allergy shot she is taking only her doctor's office should address this issue.
what happens if my daughter missed her monthly allergy shot? . my daughter's allergy doctor's office is closed until december 14th. she was scheduled to receive her monthly maintenance shot around november 19th but the office was already closed. what should we do now?
