CBS 2 Evening News highlighted Great Lakes Clinical Trials as being one of the research sites in Chicago conducting Johnson & Johnson’s two dose COVID-19 vaccine trial. J&J’s two dose study is evaluating the efficacy of the vaccine after both the first and second dose to asses protection against the virus and any potential benefits that may come with the added protection from a second dose.
Enrollment closed on March 31st, but the study has been continuing on with the other assessment visits scheduled throughout the duration of the two year study.
