 This episode of PEM Currents: The Pediatric Emergency Medicine Podcast focuses on the approach to unvaccinated or undervaccinated children aged 3–36 months presenting to the ED with fever. Host Brad Sobolewski reviews differences in immune response, risk for serious and invasive bacterial infections, and outlines evaluation strategies including labs, imaging, and empiric antibiotics. He highlights data showing increased interventions in this population and calls for local guideline development. The episode emphasizes thoughtful, individualized care in the context of rising vaccine hesitancy and declining immunization rates.

As always, I’m your host, Brad Sobolewski, and this episode is gonna focus on a challenging yet. Unfortunately, timely clinical question, what do we do with the UN or under vaccinated child who presents to the emergency department with fever? So what are we gonna go over in this episode? Well, we’re gonna compare the clinical presentation of bacterial infections in unvaccinated and unvaccinated children versus fully immunized children in the emergency department, and we will assess the need for empiric antibiotics and diagnostic testing in this challenging population. Now, before you listen to this episode, I will presume that you are all familiar with the recommended child and adolescent immunization schedule for children ages 18 and younger in the United States or wherever you live. So I’ll pause for a moment so that you can review that. Great. Welcome back, and there’s a few definitions that I will use. Unvaccinated or unm. Immunized means that you have no vaccines. Unvaccinated or under immunized means that you have some but not all of your vaccines, and you should always verify vaccine status via history EMR records and state registries. So I think the first important question to answer is, when is a child immunocompetent? And honestly, competency is sort of on a sliding scale, and a child is immunocompetent if they have a normally functioning immune system capable of mounting an effective response to infections. So this means you have intact, innate and adaptive immunity with functioning neutrophils, macrophages, T cells, and B cells. You don’t have. Severe combined immunodeficiency like a primary immunodeficiency or a secondary immunodeficiency. You’re on chemo or you’re severely malnourished. Immunocompetent kids respond to vaccines completely immunized, so greater than two doses of PCV and HIB should be immunocompetent ...
