COVID-19 seroprevalence changes over time, with infection, vaccination, and waning immunity. Seroprevalence estimates are needed to determine when increased COVID-19 vaccination coverage is needed, and when booster doses should be considered, to reduce the spread and disease severity of COVID-19 infection. We use an age-structured model including infection, vaccination and waning immunity to estimate the distribution of immunity to COVID-19 in the Canadian population. This is the first mathematical model to do so. We estimate that 60-80% of the Canadian population has some immunity to COVID-19 by late Summer 2021, depending on specific characteristics of the vaccine and the waning rate of immunity. Models results indicate that increased vaccination uptake in age groups 12-29, and booster doses in age group 50+ are needed to reduce the severity COVID-19 Fall 2021 resurgence.

Following a gluten-free diet (GFD) is known as the main effective therapy available for celiac disease (CD) patients, which in some cases is not enough to heal all patients presentations completely. Accordingly, emerging researchers have focused on finding novel therapeutic/preventive strategies for this disorder. Moreover, previous studies have shown that celiac patients, especially untreated subjects, are at increased risk of developing viral and bacterial infections, which can become a challenge for the clinician.

Background: Reliable gender-sensitive normative data is needed to facilitate mental health research and clinical utility of commonly used symptoms scales. This study establishes Danish gender-stratified norms for the 53-item and 18-item Brief Symptom Inventory (BSI-53, BSI-18), proposed attention deficit hyperactivity disorder (ADHD) symptomatology scales from the BSI-53, and the 10-item Symptom Checklist (SCL-10). This study also examines gender-differences in symptom reporting of the ADHD and SCL-10 scales, and assesses potential bias in recent SCL-10 norms.
