nasal spray vaccines

Nasal spray vaccines are a form of immunization delivered directly into the nose using a spray device. They stimulate the immune system to recognize and fight specific viruses or bacteria by activating immune responses in the mucous membranes lining the nasal passages. This method is non-invasive, easy to administer, and can promote immunity at the entry point of many respiratory infections. Nasal vaccines are especially useful for preventing illnesses like influenza and COVID-19 and may encourage a quicker immune response compared to injections. They provide an effective alternative to traditional shots, often with fewer side effects and improved compliance.
