Nasal spray prevention targets viral entry points, bypassing traditional vaccine approaches

Ewaisha argues that respiratory viruses like COVID-19 can be prevented through targeted nasal spray solutions that directly address viral entry points in the respiratory system, rather than relying solely on systemic vaccines and treatments. This represents a shift toward non-invasive, anatomically-specific prevention strategies that operate at the site of initial infection.
