Vaccine developer Intravacc has published data from a preclinical study of an intranasal whooping cough vaccine demonstrating strong immune responses in mice. The intranasal vaccine also prevented colonization of the lung, trachea, and nose by B. pertussis, the bacteria that causes whooping cough, while mice vaccinated by subcutaneous injection did experience nasal colonization.
The vaccine is based on the company’s outer membrane vesicle (OMV) technology. Intravacc CEO Jan Groen commented, “This study, showing full protection against whooping cough after intranasal immunization with our OMV based pertussis vaccine, provides us with a lot of comfort towards the development of our Covid-19 intranasal vaccine based on OMV’s”
Chief Scientific Officer Gideon Kersten said, “Intravacc’s vaccine concept has several potential advantages. Because of its composition outer membrane vesicles reduce the risk of vaccination induced selection of strains not matching with the vaccine, it induces immunity at the port of entry and it is needle free, allowing easy administration and flexible incorporation in immunization programs.”
