In order to combat potential coronavirus pandemics in the future, the Vaccines and Infectious Diseases Organization (VIDO) is working on the creation of a new universal vaccine.
According to the director of vaccine development at the laboratory located in Saskatoon, Trina Racine, this vaccine aims to protect against several types of coronaviruses, including pan-sarbecoviruses.

Pan-sarbecoviruses are a subfamily of the coronavirus family that circulate in animals and can be transmitted to humans.
The goal of this vaccine is to protect people not only against SARS-CoV-2 and these variants, but also against other viruses in the coronavirus family, says Trina Racine. The goal is also to protect the population against the possibility of another coronavirus pandemic.
In the past 20 years, three known pathogenic coronaviruses have emerged in humans, according to VIDO.
These are the SARS-CoV-1 which affected the City of Toronto in 2003, the 2012 MERS-CoV which is also known as the Middle East respiratory syndrome and the 2019 SARS-CoV-2 (COVID -19).
All of these viruses have one thing in common: they have led to infectious diseases and significant death rates.
The VIDO laboratory indicates that it is important to continue research on protective vaccines against current and future coronaviruses because of the frequency of these viruses and their impact on human health.
Through its new vaccine, the laboratory wishes not only to offer protection against the pathogens of the virus which already exist in humans, but also against those found in animals and which can potentially spread among humans.
With the panoply of COVID-19 vaccine authorized on the market, the National Advisory Committee on Immunization (NACI) recommends several booster doses.
For its part, VIDO indicates that it does not yet have data on its new vaccine to decide on the number of doses that will be necessary to protect the population against the different types of coronavirus.
Something new in science?
This is not the first time that scientists have attempted to create a universal coronavirus vaccine.

Ciro Piccirillo is co-head of the Immunology and vaccine protection pillar at CoVaRR-Net. He also holds the positions of professor and graduate program director at McGill University.
He believes that this type of vaccine would be very useful.
It’s the jackpot! That’s what everyone wants. Do we really want to dwell on being slaves to one wave after another, to endless threads of waiting?
According to him, a universal vaccine would remove all the pressure on governments, as well as on public health services.
