A new type of vaccine could be a game-changer in the fight against COVID-19, but it hasn't yet received the green light from Canada. 

< p>With the arrival of the Omicron XBB.1.5 variant, scientists believe that Canada should design a new mucosal vaccine, according to Global News. This new type of vaccine can be inhaled or taken by mouth. According to scientists, this vaccine could significantly prevent the transmission of the virus.

China and India have decided to go ahead with this vaccine. However, it still has not been approved in Canada.

A McMaster University immunology professor, Dawn Bowdish, is of the opinion that the country should accept this vaccine to hope for a return to normal.

“Until we get vaccines that actually stop transmission, we have to make trade-offs between non-pharmaceutical interventions like masks and vaccinations. If we really want to get back to the life we ​​had before the pandemic, we are going to have to invest in mucosal vaccines,” she argued.

Current vaccines have the effect of stimulating an immune response, while a mucosal vaccine could stimulate an immune response targeted for the airways, according to professor at the Faculty of Medicine at the University of Ottawa Marc-André Langlois.< /p>

It clarifies that mucosal vaccines target the virus at its first point of entry – the mouth and nose – and can stop it even before it causes infection or transmission.

“We are really focused on the point of entry, and we really want to try to complement mRNA vaccines with vaccine technology that is almost entirely dedicated to preventing the initial binding of the virus to thereby reduce transmission of the virus,” he explained.

According to Mr. Langlois, the lack of awareness of this new vaccine explains why it is not yet available in Canada.

“We we need this kind of innovation, he said. Without it, we cannot win the battle.”
