Quebec will require three injections for “adequate protection”, those who have received COVID-19 are invited to be boosted sooner

MONTREAL – Quebec’s public health has released new guidelines for people to be stimulated “as soon as possible”, including those who have recently had COVID-19, as the province prepares to make three doses the minimum for be considered “sufficiently protected”.

Quebec announced the upcoming changes in a press release on Wednesday, as it prepares to open third-dose eligibility to all Quebec adults on Friday.

All three doses will be required for the Quebec vaccine passport, which is required to enter government alcohol and cannabis retailers, as well as dining rooms in restaurants, bars and other environments that are currently closed.

However, the statement did not specify exactly when the change will occur.

“When the entire population has had the opportunity to receive its booster dose, the status” sufficiently protected “for the vaccine passport will increase to three doses,” the statement said.


“In the current epidemiological context, it is recommended to all those who wish, including those who have recently had COVID-19, to be able to obtain a booster dose against COVID-19 as soon as possible”, can – read in the press release.

“People who have contracted COVID-19 will be able to receive the booster dose as soon as their disease resolves, that is, when the symptoms have ended. “

This marks a change in the province’s public health guidelines. On Wednesday, the government’s online booking portal, Clic Santé, still recommended that people wait “eight weeks after the onset of your symptoms or a positive COVID-19 test” before making an appointment for a third dose of the vaccine. .

CTV News has asked the Department of Health and Human Services to clarify the new recommendation.


While it’s not known exactly how much immunity a person can get after catching a variant of COVID-19, the presence of more than one makes the waters muddier.

While a significant portion of Quebec’s population fell ill with COVID-19 during the province’s explosive and continuing Omicron wave, the previously dominant Delta variant was still circulating.

As community transmission has grown and testing has become more difficult to obtain, it is not so easy to tell, at this point, who got Delta and who got Omicron.

Dr Donald Vinh, an infectious disease specialist at the McGill University Health Center, said it is still not clear whether antibodies from a Delta infection will protect against the Omicron variant, and whether the first data from Africa from South suggest they won’t.

“And so we don’t necessarily want to lump these two groups of people together,” he told CTV News. “The purpose of a third dose is to protect you against the predominantly circulating variant.”

Vinh said that in an ideal world where everyone knew which variant they were getting, vaccination timelines would vary for each group.

“We don’t think that if you have been infected with Omicron you can be re-infected with Omicron in the short term,” he said, estimating that this term would last around four to six weeks, but we still cannot be sure. because “we have no data”.

“So for a directive to say if you’ve had a recent infection, once your symptoms are over take your booster dose, I think there’s a bit of intellectual thinking missing here.”
