How is normal vaccine different from nasal one?

Unlike other Covid-19 vaccines that are administered intramuscularly (or through the muscles), the nasal vaccine delivered through the nose, which is also an initial point of infection in humans.

According to a study by the University of Washington School of Medicine, the nasal delivery route created a strong immune response throughout the body, but it was particularly effective in the nose and respiratory tract, preventing the infection from taking hold in the body.
