nasal vaccination

Nasal vaccination is a method of delivering a vaccine through the nose rather than through a needle. This approach targets the immune response in the mucosal membranes of the respiratory system, where many viruses enter the body. By using a spray or drop that enters the nostrils, nasal vaccines can stimulate a strong immune response to help protect against diseases like influenza or COVID-19. The ease of administration and pain-free experience can encourage more people to get vaccinated, potentially increasing overall vaccination rates and helping to control the spread of infectious diseases.
