HVTN 405/HPTN 1901 – Research leading to a COVID-19 vaccine

SFDPH is learning more about how our bodies respond to and recover from the virus called SARS-CoV-2, that causes COVID-19.

The information we learn from this study will be used to help develop better tests for SARS-COV-2 infection and COVID-19 disease and will help in developing future vaccines and treatments.

You may be eligible if you received a positive COVID-19 test result. If eligible for a study, you will be paid for your time and participation.

The Long-term Impact of Infection with Novel Coronavirus (LIINC)

We are researching changes that happen after recovery from the virus. Specifically, how immunity develops and changes over time, as well as the effects of COVID-19 on different organ systems.

People who tested positive for COVID-19 can volunteer. You will need to give blood and saliva samples several times over the next 2 years.

COVID-19 Host Immune Response Pathogenesis (CHIRP) Study

We are working to understand why some individuals have more severe symptoms of COVID-19 while others have little to no symptoms, which may be related to your genetics, immune defenses, or personal characteristics such as your age, gender, or medical conditions. The information will be used to potentially develop vaccines, treatment, and better tests for COVID-19.

Find COVID - Return to public life

Are you curious if you can still give COVID to your family or friends? Are you worried that they may get it from you? 

We want to understand how long people are infectious with COVID as part of a household transmission study. This information will help determine how long quarantine should be, and when people can return to work or their public life.
