The 3rd dose of COVID-19 vaccine remains an exceptional measure | Coronavirus

By exception, the MSSS hears people who have an essential trip planned outside the country, in the short term, and who must meet vaccination requirements different from those in effect in Canada.

The ministry also specifies that there is no international consensus on the criteria according to which a person is recognized as adequately vaccinated.

Both in Quebec and in Canada, a viral vector vaccine (AstraZeneca or Covishield) can be combined with an mRNA vaccine (Pfizer or Moderna) in the second dose. The MSSS says it follows the recommendations of the Committee on Immunization of Quebec (CIQ) and the National Advisory Committee on Immunization (NACI) on this subject.

The government of Quebec therefore offers an additional dose of a messenger RNA vaccine people who want to travel to a country that does not recognize their vaccination status, and who therefore need to receive at least two doses of the same vaccine.

The Ministry of Health is offering this additional injection because some countries do not consider people who have received a mixed scenario vaccines as being adequately vaccinated.

What about two doses of AstraZeneca?

Discussions are also continuing between Quebec and the federal government so that mixed or two-dose scenarios of the AstraZeneca or Covishield vaccine are recognized more broadly at the international level, it was added.

The same procedures were also undertaken by Ontario.

Dr Julien Cavanagh, an infectious disease specialist based in Atlanta, has difficulty in explaining this approach for a third dose when some countries in the world have little access to vaccines.

As long as there are entire segments of humanity that are not vaccinated, there will be a playing field for variants that will continue to develop.

A quote from:Dr Julien Cavanagh

In an interview with ICI Première, immunologist André Veillette specifies that the third dose should be a matter of health, not of tourism. We don’t want to give a vaccine to people who don’t need it, he insists.

He adds that immunosuppressed people should receive this third dose as a priority.

Even if it means testing them to see in their blood if they have antibodies or not, continues the immunologist, who is a member of the Montreal Clinical Research Institute and a member of the federal working group on COVID vaccines.

The Institut national de santé publique du Québec says that 83.5% of residents aged 12 and over have received at least one dose of COVID-19 vaccine and that 62.5% are considered to be adequately vaccinated.

Quebec identified 298 new cases of COVID-19 and deplored 1 additional death in the last 3 days.
