Nasal Spray Vaccine

A nasal spray vaccine is a method of protecting against certain diseases by delivering a vaccine directly through the nose. It stimulates the immune system to recognize and fight the virus or bacteria without needing an injection. The spray uses a weakened or inactivated form of the pathogen or its proteins, prompting the body's defenses to build immunity. This approach is non-invasive, often easier to administer, and can provide effective immunity, especially in the respiratory tract where many infections begin. It’s a practical alternative to injections for some vaccines and can encourage higher vaccination rates.
