A team of researchers from INRAE ​​(the National Research Institute for Agriculture, Food and the Environment) and the University of Tours is working on a vaccine to be released into the nose.

It would resist variants and could eventually replace vaccines by injection.

The first clinical trials on animals are encouraging, according to the researchers. 

DECRYPTION

This could be the ultimate solution against Covid-19.

French researchers are working on a nasal vaccine.

It is a vaccine that would be administered through the nose.

It could supplement or even replace in the long term, vaccines by injection.

This is the goal sought by INRAE ​​(the National Research Institute for Agriculture, Food and the Environment) and the University of Tours.

In addition to protecting against the virus, this nasal vaccine would prevent any risk of contamination and therefore any risk of the virus spreading.

A solution that would complement the vaccines by injection at the beginning

What does this vaccine consist of?

This vaccine would focus on mucosal immunity.

So that your nose can acquire this powerful bulwark, the nasal vaccine would diffuse vaccine proteins encapsulated in nanoparticles into each nostril.

It is a solution that would complement current vaccines by injection.

Eight nasal spray vaccines in the evaluation phase 

"The idea of ​​a nasal vaccine would be to contribute to this protection against the disease and to provide additional protection against the contagiousness of the disease and to be able to protect individuals so that they are no longer contagious among themselves. ", explains Mathieu Epardaud, in charge of preclinical tests at Inrae.

"This could really be the solution to be able to return to life, before the epidemic. Because we will no longer need to wear a mask and we will no longer need to carry out barrier gestures," he recalls. 

There are currently eight anti-Covid nasal spray vaccines in the clinical evaluation phase, listed by the World Health Organization.
