Nearly all Montreal-area teenagers age 12 to 17 have developed COVID-19 antibodies, according to a CHU Sainte-Justine study.
The study, led by pediatric infectious diseases specialist Dr. Caroline Quach, shows the highest level of antibodies — 97 per cent — is in teens age 12 to 17, when taking into account those who developed antibodies through either vaccination or natural infection.
“It gives us enough information to tell us there have been a lot of infections and recently, in all likelihood, Omicron [infections],” Quebec’s interim public health director, Dr. Luc Boileau, who commissioned the study, said at a news conference Wednesday.
Omicron has been the dominant COVID-19 variant in the province since December 2021, Quebec’s Health Ministry confirms.
Data from Quebec’s institute of public health (INSPQ) published Wednesday shows nearly three million Quebecers have been infected with Omicron.
