About this trial

The purpose of this study is to see whether dried blood spot (DBS) samples can measure inflammatory biomarkers as accurately as venous blood samples.

Investigators will be measuring inflammatory biomarkers changes obtained in DBS compared with paired venous blood samples following a controlled physiological stressor (i.e. after a vaccine or other planned event that can cause a temporary rise in inflammation).

These findings will help understand whether DBS can be a reliable alternative to traditional blood draws in future research and healthcare.

Eligibility criteria

Qualifiers

Men or women aged ≥18 years, who are planning to receive a seasonal vaccine OR have a scheduled acute stressor*.

Disqualifiers

Any self-reported active/recent use of cocaine, injection drugs, or amphetamines

Acute worsening of a known chronic health condition within the previous 30 days (e.g., of IBD, COPD, asthma, rheumatologic disease)

Known severe allergy or intolerance to the planned vaccine
