The race for cures: when will you be vaccinated against VID-C19?

CHSLD residents and health care workers will be the first to be vaccinated against VID19 when Canada receives its first doses in early 2021. But after that, the choices may be more complicated to make, experts say.

“The people most affected in terms of deaths and hospitalizations, health care workers, are clearly groups that will be quickly targeted,” says Dr Gaston De Serres, medical epidemiologist at the Institut national de santé publique du Québec.

Then,” he says, “there are all kinds of more complicated issues that will arise, as there won’t be enough doses to vaccinate everyone at the same time. »

Canada has hit the mark with its advance purchase program for vaccines from major pharmaceutical companies. A total of 152 million doses of the first three vaccine candidates with encouraging results, Pfizer, Moderna and AstraZeneca, have already been reserved.

But that doesn’t mean that all these doses will be shipped at the same time.

Ottawa expects the initial lots to arrive gradually in the first three months of 2021. Three million people are expected to be vaccinated during this period.

Yesterday Justin Trudeau argued that the majority of Canadians will be vaccinated by next September if all goes well.

England’s got her list.

Unlike some states, such as England, specific vaccination priority lists by population group have not yet been unveiled in Quebec.

The National Director of Public Health, Dr Horacio Arruda, however, gave clues yesterday by explaining that the most vulnerable – “that is, the elderly” – will be protected first, along with some key workers and some remote communities, but without adding more.

Quebec has entrusted the vaccination operation to the new Assistant Deputy Minister of Health, Jérôme Gagnon.

According to the Dr De Serres, the calendar chosen by England is “simple to manage”, because it works essentially by age group. But other considerations should be taken into account, he argues, such as those relating to the vaccination of essential workers who do not work remotely in non-health sectors.

He gives the example of those responsible for the proper operation of water filtration plants, or of employees in critical Hydro-Québec positions.

And that’s where the questions come in. “Who will determine these critical positions? We’re getting into something that has to be decided at the organizational level, and it’s complicated,” says Dr. De Serres. But in the end it will be up to the government to arbitrate, he says.

The professors

For his part, epidemiologist Nimâ Machouf says that teachers should be included in the category of people to be vaccinated as a priority.

“Teachers are essential workers because we want the school to work,” she says.

Once at-risk populations and key workers have been immunized, it will be the turn of the general population.

Can we then fear a kind of traffic jam because of the large number of people to be treated?

I don’t think it will be a problem,” says Ms. Machouf. We’ll be up and running, the system will be efficient, we’ll be able to deliver vaccines quickly. »

The National Health Service England (NHS England) has developed a recently unveiled schedule of vaccinations against COVID-19 by population group.

Here it is, with the expected start dates of the vaccination:

  • Health care workers and staff and residents of homes for the elderly: early December
  • Persons aged 80 and over: mid-December
  • Persons aged 70 to 79: end of December
  • Persons aged 65 to 69: early January
  • Persons aged 65 and under at risk: early January
  • Persons aged 50 to 64: mid-January
  • All persons aged 18 to 49: end of January, with the bulk of the vaccination in March.

What Doc Béliveau thinks about it

The main obstacle is overcome

If someone had said last spring that the main concern for 2021 would be the effective delivery of three vaccines against COVID-19, he would probably have been dismissed as being overly optimistic.

That’s how quickly scientific research has found the counter-attack to this fearsome virus!


While there are logistical challenges to the distribution of these vaccines, the main hurdle has been overcome and the final stage of the fight against VIDOC is now entering its final phase.

The limiting stage of this war was really the scientific part!

Distributing and administering a vaccine, we know how to do it…
