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.
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.”
