Stanford Medicine begins enrolling for COVID-19 vaccine trial | News Center

Stanford Medicine has joined a large, Phase 3 clinical trial of an experimental vaccine against COVID-19.

The trial will test whether the vaccine, which is produced by the Janssen Pharmaceutical Companies of Johnson & Johnson, protects people from the disease. It will enroll some 60,000 people at about 180 sites around the world. The Stanford site is expected to enroll about 1,000 participants.  

Participants will receive either the vaccine or a placebo, and their health and immune responses will be monitored for about one year after their initial visits. If any participants become ill with symptoms of COVID-19, a health care provider will go to their homes to assess their health and collect a nasal sample to test for the presence of the novel coronavirus. If they are infected, Stanford physicians will monitor their disease progression. 

“We’re enrolling a wide variety of participants, but we are particularly interested in those who feel like their home or workplace exposure puts them at risk,” said Philip Grant, MD, assistant professor of medicine and the trial’s principal investigator at Stanford. “Teachers, grocery store workers, people who live in multigenerational households, health care workers and students on campus would all be good candidates for participation.”

Participants will be followed for two years and one month. They are expected to visit the trial site eight times: six in the first year and two in the second year. The initial visit will last about two hours; subsequent visits will consist of a short blood draw and symptom screening. If a participant develops COVID-19 during the study period, additional visits may be required.
