A team of scientists at uOttawa is aiming to create something new and revolutionary — a needle\u002Dfree, self\u002Dadministered nasal vaccine that blocks infection
Why, at this point in the pandemic, with highly successful mRNA and other vaccines widely available, are Canadian researchers working to develop new mucosal vaccines against COVID-19? And why should people care?
Current COVID-19 vaccines administered via needles, produced within months of pandemic declarations, were approved for emergency use based on proof that they could prevent severe disease and deaths, which they did. They did not entirely stop infection or transmission. Because mucosal vaccines can be delivered through the mouth and nose, they can be self-administered, making delivery significantly easier and cheaper, something that is crucial in parts of the world with fewer resources. They also do away with the need for injections.
The mucosal vaccine research at uOttawa is to develop a prototype, Langlois said. Where it goes from there depends on funding. “Right now it is limited, until we make a strong case that it is effective and then we can increase our team size to move things along faster. “Canada needs much higher sovereignty over vaccine production and bio-manufacturing of drugs. We are highly reliant on foreign industry. That has been a lesson of the pandemic.”OTTAWA – March 02, 2023 – Marc-André Langlois and Allyson MacLean, uOttawa researchers, are working on a nasal covid booster vaccine that is plant based.
