According to the report, the vaccine could be feasible and effective, especially for mass distribution. It works on the same mechanism as the influenza vaccine.

The GlobalData drugs database revealed that currently, five intranasal vaccines for coronavirus are under development. All these vaccines contain SARS-CoV-2 spike protein in their formulations.

Scotty Chung-Siu, MPH, Senior Analyst at GlobalData, stated, as cited in the Express Pharma report: “Nasal sprays are far less invasive for the recipient than the intramuscular injection alternative, as the drug can be rapidly absorbed through the nasal mucosa since it is supplied by many blood vessels.”

The intranasal spray consists of genetic segments of Covid-19’s spike protein. The vaccine mimics the infection of respiratory viruses to stimulate the immune response.
