Health care workers sometimes think the 2 oral rotavirus vaccines are injectable formulations and mistakenly administer them with a syringe, according to a recent account in the Morbidity and Mortality Weekly Report.
Investigators at the Centers for Disease Control and Prevention (CDC) recognized the errors when they searched records in the Vaccine Adverse Event Reporting System (VAERS) for the period between January 2006 and August 2013. Overall, they found 66 reports of errors or adverse events involving oral rotavirus vaccine. Of the total, 39 were reports of the oral vaccine being administered by injection.
