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.

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.

It is anticipated that 10,000 subjects will be enrolled in this study. It is preferred that enrollment is balanced by sex; however, it is not required. All efforts will be made to provide racial/ethnic balance, with a goal of 50% underrepresented minorities.
