As the world continues to grapple with the ongoing COVID-19 pandemic, new questions have emerged about the origin of the virus and whether one of its more pathogenic variants, Delta, may have originated from Pfizer Inc.'s India operations.

HHS oversight of gain-of-function research “does not fully meet key elements of effective oversight" and "fell short in terms of transparency and performing reviews."
