Plain-language summary

VOICES is a longitudinal, prospective, observational study that will enroll up to 10,000 subjects of diverse racial backgrounds being administered an emergency use authorized COVID-19 vaccine, for collection and analysis of stool and blood samples. It has recently been shown that the gut microbiome, the collection of microbes that line our GI tract, play a significant role in vaccine immune response and severe complications from COVID-19. The identification of biomarkers may aid in predicting response to vaccination and are critical towards improving vaccine-induced immunity. These real-world patient derived biomarkers could be used as interventional targets for the design of innovative adjuvant co-therapies that can boost an effective immune response to the vaccine, enhancing efficacy for a broader population, including those at most risk. Subjects who meet the entry criteria will provide two samples each of blood, one prior to and one following vaccine administration. Follow-up questionnaires will be sent at 3, 6, 9, and 12 months to determine if participants have contracted COVID-19 or have experienced any adverse effects of the vaccine. Nasal swab samples will also be collected from participants that have contracted COVID-19. The samples will be analyzed to determine the impact of gut microbiome composition and function on the immune system and vaccine efficacy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Men or women who are ≥ 18 years old and expecting to receive the SARS-CoV-2 vaccine within the next 30 days. * Subjects who are able to provide written informed consent. Exclusion Criteria: * Subjects with known HIV, Hepatitis A, Hepatitis B, Hepatitis C, or SARS-CoV-2 infection within 4 weeks of vaccination * Subjects without the mental capacity to complete either a written or online questionnaire, alone or with assistance, or make sound decisions * Women who are pregnant, plan on becoming pregnant, or are nursing.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring
