New Drug-Free Nasal Spray Shows Promise Against Respiratory Infections

Researchers at Brigham and Women’s Hospital have developed a groundbreaking drug-free nasal spray that shows promise in blocking and neutralizing respiratory infections, including COVID-19 and influenza. This innovative spray creates a protective gel-like barrier in the nasal cavity, potentially offering nearly 100% protection against respiratory pathogens. As respiratory infections continue to pose a global health threat, this new approach could play a crucial role in enhancing public health and safeguarding communities.
