Faith Initiative expands to help build bridges between community and HIV vaccine trials

SEATTLE (December 14, 2021) – While the rapid development of effective vaccines has helped combat the COVID-19 pandemic, key communities – especially people who are living with HIV –  remain disproportionately impacted, and are at higher risk of severe disease and death. Finding an effective HIV vaccine is critically important, and to that end, the HIV Vaccine Trials Network (HVTN) is launching an expanded Faith Initiative that will help advance the work of finding a cure.

Landmark COVID-19 vaccine trial in sub-Saharan Africa is the first to study the efficacy of mRNA COVID-19 vaccines in people living with HIV

Formation of the COVID-19 Prevention Network (CoVPN) and official website launch

CoVPN Logo
  • The COVID-19 Prevention Network (CoVPN) was formed by the National Institute of Allergy and Infectious Diseases (NIAID) at the US National Institutes of Health to respond to the global pandemic. Using the infectious disease expertise of their existing research networks and global partners, NIAID has directed the networks to address the pressing need for vaccines and monoclonal antibodies (mAbs) against SARS-CoV-2. The HVTN is one of four NIAID-funded networks that constitute the CoVPN.
