Research Roundup: A Global Health Security Index report, US global vaccine initiative, and mRNA HIV vaccine
In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week.
The US Agency for International Development on Monday announced the creation of the Initiative for Global Vaccine Access, or Global VAX, a new initiative to accelerate COVID-19 vaccination efforts around the world. Global VAX will aim to get COVID-19 shots into arms as well as enhance international coordination to identify and rapidly overcome access barriers, particularly in sub-Saharan Africa. These efforts will include bolstering cold chain supply and logistics, service delivery, vaccine confidence and demand, human resources, data and analytics, local planning, and vaccine safety and effectiveness. The US government will supply $400 million in American Rescue Plan Act funds to support this work, adding to the $1.3 billion that has been previously committed for vaccine readiness.
An experimental mRNA-based HIV vaccine showed promise in early animal studies, according to study results published Thursday. The research, conducted by the National Institute of Allergy and Infectious Diseases (NIAID), Moderna, and other institutions, showed the vaccine was safe and prompted antibody and cellular immune responses against an HIV-like virus in mice and monkeys. Rhesus macaques that received a priming shot followed by multiple boosters had a 79 percent lower per-exposure risk of infection by simian-human immunodeficiency virus compared to unvaccinated animals. The mRNA vaccine, which uses the same technology deployed in two effective COVID-19 vaccines, combines several features that could help overcome shortcomings of other experimental HIV vaccines, according to NIAID.
