theMSSS explains that this decision was made following a new opinion from the Comité sur l’immunisation du Québec (CIQ), which recommends a booster dose for young people in this age group who are at higher risk of complications related to COVID-19.
Young people living in closed congregate settings should also get this booster dose given the particularly high risk of transmissioncan we also read.
Young Quebecers should, however, receive a booster dose only three months or more after the last dose of vaccine received against COVID-19.
The Ministry of Health recalls that studies in adolescents, as in adults, reveal
decreased protection against infection over time. A booster dose would be more effective in the short term in young people aged 12 to 17 against new variants, including Omicron.
The CIQ recommends Pfizer’s vaccine for this age group because of a
slightly lower risk of developing complications [myocardite] after vaccination.
