HVTN Responds - No Justice, No Progress


George Floyd, Gabriella Nevarez, Michelle Cusseaux, Alexia Christian, Breonna Taylor, Trayvon Martin, Michael Brown, Charlena Lyles, Stephon Clark, Terence Crutcher, Alton Sterling, Philando Castile, Che Taylor, Eric Garner, Mi’Chance Dunlap-Gittens, Laquan McDonald……the list of Black/African American people murdered continues to grow. This is unacceptable.

Epidemics and pandemics are magnifying glasses for tragedies. Those of us who have fought to address the biological outcomes of racial injustice work every day in communities where the human cry of “no justice, no peace” is resonating off the walls. It echoes with us as we try to work in a world where structural racism and discrimination consistently highlight difference.

COVID-19 Prevention Network (CoVPN) logo

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

  • 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.

A Tale of Two Interdependent Pandemics

According to the World Health Organization (WHO), there have been over 20 million confirmed cases of Covid-19 and over 700,000 associated deaths throughout the world. These numbers are so staggering that most of society remains shut down until a safe and effective vaccine is brought to market. 

Having already claimed a significant number of lives worldwide, Covid-19 is one of the most acute global health crises many people – especially Americans – have ever faced. Because fully reopening society and repairing the economy is contingent on developing a vaccine (while taking the necessary precautions to prevent transmission of Covid-19), many Americans are just now coming to grips with what that process entails.
