Vaccine Administration Errors

We inadvertently gave both pneumococcal conjugate (PCV) and pneumococcal polysaccharide (PPSV) vaccines at the same visit. We are looking for guidance.

Although PCV and PPSV23 should not be administered at the same visit, CDC does not recommend repeating either vaccine dose should this occur. You should inform the patient of the error and let them know that they will not need to repeat either dose.
