HVTN 307

This study is assessing the safety and immunogenicity of ferritin nanoparticles expressing native-like HIV-1 envelope trimers followed by an mRNA boost in adults without HIV between the ages of 18 to 55 . This study is currently enrolling participants.

HVTN 303

This study is assessing the safety, tolerability, and immune response of an adjuvanted HIV-1 fusion peptide conjugated vaccines in healthy, HIV negative adults between the ages of 18 to 50. This study is currently enrolling participants.

SARS-CoV-2 Household Transmission

This study is assessing whether COVID-19 vaccines reduce SARS-CoV-2 transmission within households and how readily SARS-CoV2 transmits to household members in an effort to determine better quarantine measures. This study is currently enrolling participants.

HVTN 302

This study is assessing the safety and immune response of 3 experimental mRNA HIV vaccines in healthy, HIV negative adults between the ages of 18 to 55. This study is currently enrolling participants.

vYF02

This study is comparing the immunogenicity and safety of an investigational yellow fever vaccine with the previously approved YF-VAX vaccine. The main purpose of the study is to determine if the study vaccine is safe and creates comparable immune responses to that of the YF-VAX vaccine. This study is currently enrolling.
