Acute Hyperglycemia After Influenza Vaccination in a Patient With Type 2 Diabetes.

Abstract

There are 29.1 million people in the United States living with diabetes (1). Except in cases with contraindications, annual influenza vaccination is recommended for all people with diabetes to reduce morbidity, mortality, and health care costs associated with influenza illness (2,3). There were 12 influenza vaccines available for the 2016–2017 influenza season. These vaccines were categorized into inactivated or live, quadrivalent or trivalent, and high-dose or standard-dose formulations (2). Common adverse reactions of pain, soreness, fever, muscle aches, fatigue, redness, or swelling may occur after intramuscular vaccine administration (4). Hyperglycemia is not noted as an adverse reaction in vaccine package inserts; however, reports of its occurrence have been documented in the Vaccine Adverse Event Reporting System (VAERS) (5). Since 1991, there have been 946 reports of hyperglycemia with all available vaccines and 361 reports of hyperglycemia with all types of influenza vaccines. When looking specifically at the trivalent influenza vaccine, there have been 235 reported cases, with 70.6% reported during the first 4 days after vaccine administration (5). In light of these reports, a literature search was performed to obtain more information about acute hyperglycemia after vaccine administration. The search was performed with the advanced search option in PubMed using the terms hyperglycemia,” “blood sugar,” “blood glucose,” “vaccines,” “influenza vaccine,” “diabetes,” and “immunizations.” The search failed to yield any literature reports specifically related to blood glucose …
