Quebec says only people at risk who haven't had COVID-19 should get booster dose

MONTREAL — Only people who are considered at risk for severe COVID-19 — and who haven't already been infected — need to get a booster dose, Quebec's public health director said Thursday.

MONTREAL — Only people who are considered at risk for severe COVID-19 — and who haven't already been infected — need to get a booster dose, Quebec's public health director said Thursday.

The vast majority of Quebecers have hybrid immunity — protection through vaccination and through a SARS-CoV-2 infection — making regular boosters unnecessary, at least for this winter and spring, Dr. Luc Boileau told reporters.

"People with hybrid immunity … have a very good protection against a severe form of the illness," Boileau said. "And this immunity lasts for a long enough time that we can propose changes."

Those who have been vaccinated but haven't contracted the virus are also protected against severe COVID-19, he said, but their immunity "has a tendency to drop with time."

Quebec's vaccination committee decided to focus the province's immunization policy on preventing hospitalizations and deaths, he said. People who are 60 and older or who have chronic illnesses, health workers, pregnant women and those who live in isolated regions are among the people who should get a booster every six months — but only if they have never caught the virus, Boileau said.

Dr. Caroline Quach-Thanh, chairperson of Quebec immunization committee, said the data shows that people already vaccinated for COVID-19 who have contracted the virus "maintain their protection."

"Adding a dose doesn't add a lot protection for severe (illness)," she said.

Health officials estimate that more than three-quarters of Quebecers under 60 have had COVID-19 over the past three years, while about half of those over 60 have caught the virus.

Boileau said only people who are immunocompromised should continue getting boosters even if they've been infected, "because their immunity could be affected by their condition."

Before Thursday's announcement, boosters were recommended for all people considered at risk of severe COVID-19. Boileau said COVID-19 vaccines will remain available to anyone who wants one. "We won't refuse anyone," he said.
