Outcome Measures
Primary Outcomes (1)
Positive and Negative Affect Schedules Score
We will compute change in scores on the PANAS-x subscales between baseline and day 1. Self reported assessment that contains both positive and negative words and phrases that describe different feelings and emotions. Subjects read each item and mark the appropriate answer for how they feel right now as they fill out the form. Possible answers and the associated score are: (1) Not at all, (2) A little, (3) Moderately, (4) Quite a bit, (5) Extremely. To rate, responses to items in each scale are summed. The scales in the PANAS are listed below with the number of items in that scale in parentheses followed by the total range of the scale. General Dimensions Negative Affect (10) 10-50 General Dimensions of Positive Affect (10) 10-50 Negative Emotion Fear (6) 6-30 Hostility (6): 6-30 Guilt (6): 6-30 Sadness (5) 5- 25 Positive Emotion Joviality (8) 8-40 Self-Assurance (6) 6-30 Attentiveness (4) 4-20 Other Affective States Shyness (4) 4-20 Fatigue (4) 4-20 Serenity (3) 3-15

Depression Subjects: Influenza Vaccine
EXPERIMENTALSubjects will receive a quadrivalent inactivated influenza vaccine, for the appropriate season/year of enrollment. The vaccine will be administered by the PI or similarly trained clinician, into the deltoid muscle as directed
Healthy Subjects: Influenza Vaccine
ACTIVE COMPARATORSubjects will receive a quadrivalent inactivated influenza vaccine, for the appropriate season/year of enrollment. The vaccine will be administered by the PI or similarly trained clinician, into the deltoid muscle as directed
Interventions
The appropriate quadrivalent influenza vaccine for the give year will be given to subjects.
Eligibility Criteria
You may qualify if:
- Adults age 18-60
- Able to provide written informed consent directly, without use of a proxy
- Able to speak and write in English sufficiently to undergo consent and to complete self reports
- Currently meets criteria for a Depressive Episode and a diagnosis of MDD according Mini International Neuropsychiatric Interview (MINI)
- Depressive severity of ≥ 12 on the Quick Inventory of Depression Symptomatology, Clinician Rated (QIDS-C), corresponding to more than mild depression severity, but \<21, indicating not severe
- No lifetime Axis I diagnosis on the MINI
- QIDS-SR score \<6 indicating no depression
- CRP at screening of \<1mg/L.
You may not qualify if:
- Active, unstable, or serious medical illness (e.g. requiring urgent out-patient or higher level of care) as determined by history and lab examination at screening. For example, subjects with untreated cardiovascular disease (blood pressure above 140/80 on repeated measurements, history of cardiac event without medical follow up) or untreated diabetes (based on symptoms and elevated fasting blood sugar at screening) will be excluded.
- Has received the influenza vaccine for the current season or within the last 12 months
- Infection with fever or otherwise clinically significant in the last two weeks. Subjects with elevated white blood cell count at screening will also be excluded.
- Current and within the last 3 months meeting criteria for tobacco use disorder.
- Previous severe adverse event associated with IIV
- History of allergy to any component of the IIV
- History of Guillain-Barre Syndrome
- Pregnancy
- Otherwise judged unable to comply with study procedures or unsafe to participate by study clinician
- Life-time history of mania, hypomania, or psychosis on the MINI
- Meets or has met criteria for substance abuse or dependence in the last 6 months (3 months for nicotine)
- Meets or has met criteria for any eating disorder in the last 6 months
- Baseline suicidal ideation above "passive" defined as thoughts of death or dying (e.g. wish for natural death) without thoughts of active methods (e.g. overdose) or intent to die, as determined using the Concise Health Risk Tracking Scale (CHRT) (assessment interval "the last week") and clinician interview.
