International – Nanoparticle vaccine against various coronaviruses

Coronaviruses have caused three major epidemics in the past 20 years—SARS, MERS, and the current COVID-19 pandemic. All three viruses belong to a group called betacoronaviruses (betaCoVs).

These viruses began as animal coronaviruses that jumped to human hosts. A vaccine that protects against a range of betaCoVs could prevent future outbreaks as well as help contain the current pandemic. A team of researchers led by Drs. Kevin Saunders and Barton Haynes at Duke University School of Medicine attempted to create such a vaccine. NIH’s National Institute of Allergy and Infectious Diseases (NIAID) and National Cancer Institute (NCI) supported the work. It was described in Nature on May 10, 2021…
