Brief Summary
This is a randomized, double-blind clinical trial involving emergency medicine and internal medicine healthcare providers as participants. The intervention involves the administration of the seasonal influenza vaccine or a saline placebo; this protocol is used in psychoneuro-immunology to simulate a state of mild illness. The primary aim is to examine whether acute inflammation induced by receiving the vaccine affects decision-making on standardized psychological reaction time tasks and questionnaires. Participants attend two laboratory sessions on consecutive days, receive either a seasonal influenza vaccine or a saline placebo at the first session, provide blood samples to measure inflammatory cytokines, and complete a series of standardized assessments of medical decision-making and social attitudes. Participants who received the placebo during the first session will receive the vaccine during the second session. Overall, the study is designed to examine how adverse provider conditions particularly acute inflammation, burnout, and concerns about one's own health affect provider judgments and healthcare-related decision-making. The primary hypothesis is that providers experiencing greater adverse conditions at the time of research participation would have altered decision-making compared to those experiencing fewer adverse conditions.

Outcome Measures
Primary Outcomes (2)
Testing Automatic Judgments: "Implicit Association Test"
This task calculates a "d" score across trials to quantify the strength of implicit associations. Higher d scores indicate more negative automatic attitudes.
2 days
Testing Deliberate Judgments: "Feeling Thermometers"
Explicit attitudes are assessed via 100-point Feeling Thermometers that ask for feeling toward different patient groups. Lower values indicate more negative attitudes.
2 days
Secondary Outcomes (4)
Questionnaire Assessing Social Avoidance: "Patient Sorting Task"
1 day
Questionnaire Assessing Perception of Others' Pain: "Threshold for Detecting Pain on Faces"
2 days
Questionnaire Assessing Cognitive Depletion: "Stroop Task"
2 days
Questionnaire Assessing Motivation: "Motivation to Respond without Prejudice Scale"
2 days
Study Arms (2)
Influenza Vaccine Injection
EXPERIMENTALReceives the influenza vaccine at the end of Session 1
Placebo Injection
PLACEBO COMPARATORReceives a saline placebo injection at the end of Session 1
Interventions
A single administration of a seasonal trivalent cell-based influenza vaccine delivered by injection into the arm at the end of the first study session.
Control group will receive a saline placebo injection at the end of Session 1
