PG - 3747-3751 LID - S0264-410X(20)30418-7 [pii] LID - 10.1016/j.vaccine.2020.03.039 [doi] AB - BACKGROUND: Annual influenza vaccination is recommended for persons 6 months or older and vaccination in infants less than 6 months old is a vaccine administration error. There are limited safety studies in this population, particularly among infants less than 6 weeks old. METHODS: We searched the U.S. Vaccine Adverse Event Reporting System (VAERS) database for reports of adverse events (AEs) following influenza vaccination in infants less than 6 months old for the 2010-2018 influenza seasons. We conducted a descriptive and qualitative analysis of reports to describe AEs and identify possible risk factors. RESULTS: In total, 114 reports were identified; only 21 reported a specific AE. Pyrexia, irritability, crying and diarrhea were the most common symptoms. There were 12 reports involving newborns; the most common circumstance cited was confusion with the birth dose of hepatitis B vaccine. The following risk factors were identified: (1) individuals getting vaccinated together resulting in patient mix-ups; (2) healthcare provider not verifying the patient's information; (3) individual provider confusion due to similarities in vaccines' packaging and names of vaccines that sound alike. CONCLUSIONS: Reports identified of influenza vaccination in infants less than 6 months old indicate that vaccination errors in this age group are occurring and healthcare providers who vaccinate infants should be aware of how to prevent such events. Our study adds to the existing literature by providing valuable information regarding the general absence of serious adverse events in the case of vaccination errors associated with inadvertent influenza vaccine within this population.
