Nasal spray prevention shifts viral defense from treatment to non-invasive interception

Ewaisha argues that viral pandemic prevention is shifting from post-infection treatment and vaccination toward non-invasive, targeted prevention strategies deployed at the respiratory system's viral entry points. This reframing represents a fundamental change in pandemic preparedness: blocking infection before it establishes rather than managing disease after symptoms emerge.
