“Researchers led by Dr. Dan Barouch of Beth Israel Deaconess Medical Center used monkeys called rhesus macaques to look at levels of antibodies and immune cells required to prevent reinfection with the virus.
The study was funded in part by NIH’s National Institute of Allergy and Infectious Diseases (NIAID), Office of the Director (OD), and National Cancer Institute (NCI). Results were published on December 4, 2020, in Nature.
At A Glance
- Monkeys with the highest levels of antibodies against SARS-CoV-2, the virus that causes COVID-19, were best protected against reinfection.
- Immune cells called T cells also helped prevent reinfection and may be especially important if antibody levels are low or decline over time”
