Nasal sprays are being tested as an alternative to injections for vaccines against COVID-19, the flu, RSV, and other diseases. Early trials in the U.S. have shown success, with two nasal vaccines generating immune responses against COVID-19. Researchers believe that nasal vaccines could offer faster and stronger protection by activating the immune system in the nose and mucosa. They could also be cheaper and easier to transport, potentially reducing vaccine access inequities. However, there are technical challenges to overcome in delivering nasal vaccines and measuring immune responses in the nose. Nasal vaccines target viruses and bacteria that enter through the nose and mouth, stimulating the mucosa and triggering both immediate and long-term immune responses. They have the potential to prevent breakthrough infections and may be easier to administer and store than injected vaccines. [Extracted from the article]
