Safety of vaccines administration in hereditary fructose intolerance

Abstract

Abstract Patients with hereditary fructose intolerance need to follow a life-long fructose dietary and drug restriction to prevent symptoms of intoxication. Concerns about vaccines administration have been manifested overtime, for the risk of a life-threatening acute intoxication. For this reason, at Ospedale Pediatrico Bambino Gesù we performed a deepen research from open sources, datasheets and Pharmaceutical Companies informations from the most common Italian and European vaccines, which are carried out in infancy and childhood. As a safe threshold of 2.4 mg/kg/dose was recently established for oral and parenteral (other than i.v.) route, the manuscript clarifies the safe administration of majority of vaccines in patients with hereditary fructose intolerance.
