Brief Summary:

During the study, members of different neighborhood and digital communities will be followed post COVID-19 vaccination.

Injection-site (local) and systemic reaction data will be assessed on vaccination day and afterwards using either web surveys or personal communication, depending on study participant preference.

Hypothesis to be tested The safety profile and the magnitude and durability of immune responses to the COVID-19 vaccines as well as adverse reactions depend on health conditions, metabolism and microbiomes.

Condition or disease Intervention/treatment
COVID-19 Vaccines Drug: Vaccine

Detailed Description:
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was declared a Public Health Emergency of International Concern in January 2020 and upgraded to pandemic in March 2020. First vaccines to prevent COVID-19 were authorized for emergency use in the US in December 2020, but a number of unknowns still remains. One of these unknowns is the relationship of the microbiota, gut dysbiosis and impaired metabolism with active immunity to pathogens and vaccines and tolerance to antigens. Study groups will be based on age, metabolism and self-reported symptoms. Data will be collected continuously via surveys and investigator-participant interactions, as needed. Statistical methods used will be the ones with the greatest power.
