Impact on meningococcal disease of different vaccination strategies with 4CMenB and MenACWY-CRM197 in infants and adolescents in Argentina.

Background: Invasive meningococcal disease (IMD) is a life-threatening disease, primarily affecting infants and children. Argentina introduced routine meningococcal vaccination in infants and adolescents in 2017, with MenACWY vaccination targeting serogroups A, C, W, and Y (current National Immunization Program [cNIP]). Serogroup B, more prevalent since 2015, became predominant in children.

SARS-CoV-2 seroprevalence and mental health of school staff: a cross-sectional study of schools from four areas of Montreal, Quebec in 2021.

Objectives: To assess the seroprevalence of infection-acquired SARS-CoV-2 and the mental health of school/daycare staff in the months after reopening of schools in Montreal, Quebec (Canada) in the Fall of 2020 and whether these varied by school and participant characteristics.

Design: A cross-sectional design based on a convenience sample of schools/daycares and staff was used as the originally planned longitudinal design was no longer feasible due to obstacles in recruitment, for example, teacher's strike.

Setting: Forty-nine schools/daycares in four Montreal neighbourhoods from March to October 2021.

Meningococcal burden of disease in Argentina: 10 years epidemiologic review.

Invasive meningococcal disease (IMD) is an uncommon but serious and potentially fatal condition, mainly affecting infants. In 2017, Argentina introduced a vaccination program against serogroups A, C, W and Y (MenACWY) for infants aged 3, 5 and 15 months and adolescents aged 11 years. The objective of this study was to review the burden of IMD in Argentina in 2010-2019.
