The CISSS calls for vaccination

Faced with an increase noted since 2022 in serious infections linked to meningococcus, particularly for those aged 10 to 25, the Chaudière-Appalaches Integrated Health and Social Services Center (CISSS-CA) has launched a call for vaccination against meningococcus to fourth and fifth secondary students and people born before October 1, 2008 who are under 18 years old.

Even if children have already been offered vaccination against meningococcal type C in two doses, at the age of 18 months and in secondary three, they are still at risk for other types of meningococci.

“Meningococcus is a bacteria that 5 to 10% of healthy people carry in their throat. It is transmitted by contact with secretions from the nose or throat of an infected person. There are several serogroups of meningococcus. The main ones are A, B, C, Y and W. It can rarely cause a serious infection, such as meningitis or a blood infection. These serious infections can lead to serious complications and even death,” explained Jessica Poiré, publicist in the communications and public relations department of the CISSS-CA.

Vaccination in schools

Thus, with the increase observed in recent years, Quebec recently made the decision to replace the vaccine against type Y administered in secondary school three with a quadrivalent vaccine for serogroups A, C, W and Y for the immunization of adolescents.

“Replacing the monovalent C vaccine with a quadrivalent ACWY vaccine for the vaccination of adolescents ensures direct protection against invasive infections of serogroups C, Y and W which are currently circulating in Quebec and above all prevents outbreaks caused by virulent clones. belonging to these serogroups. The Quebec Immunization Committee therefore recommended a change to the vaccination program for secondary 3 students. Then, following the persistence of the circulation of virulent strains of serogroup Y in the population of Quebec during the spring and summer 2023, the Committee on Immunization of Quebec (CIQ) also recommended a catch-up vaccination for young people in secondary 4 and 5 for the 2023-2024 cohort,” indicated Jessica Poiré.

To ensure this vaccination catch-up, tours are currently taking place in schools in the region.

“Nurses check vaccination records in schools by making rounds in each school to vaccinate students according to a pre-established schedule from now until the end of next May for all of Chaudière-Appalaches. At the same time, we offer appointment times at the local community service center (CLSC) for students who could not be vaccinated at school,” explained Jessica Poiré.
