Article Synopsis
- * A study involving 4,488 young women assessed the vaccine's effectiveness against specific HPV types, finding high efficacy rates of 93.5% for HPV-16 and 89.5% for HPV-18, with additional cross-protection against other types.
- * Results showed that the vaccine's effectiveness was similar for women who participated in catch-up vaccinations compared to those who received routine vaccinations, indicating both approaches are equally effective.
Article Synopsis
- Enteric hepatitis A virus (HAV) often goes unnoticed in children but can severely affect adults; the study aimed to improve surveillance during an outbreak at a primary school.
- Researchers used passive samplers in sewage to detect HAV RNA from November 2022 to March 2023, finding that 25% of samples tested positive and matched the strain from the symptomatic cases.
- The study concludes that sewage monitoring with passive samplers is an effective tool for quickly detecting HAV, identifying unnoticed infections, and enhancing public health responses during outbreaks.
Background: Since June 2017, oral pre-exposure prophylaxis (PrEP) has been reimbursed in Belgium for people at substantial risk of HIV. To inform the national PrEP programme, we described sociodemographic characteristics of PrEP users, PrEP dispensing practices, testing for HIV and sexually transmitted infections (STIs; gonorrhoea, chlamydia and syphilis), and incidence of HIV and STIs.
Methods: Analysis of routinely collected social health insurance claims data from all individuals who were dispensed at least one PrEP prescription between June 2017 and December 2019.
Objectives: This study aimed to assess associations of potential risk factors with human papillomavirus (HPV) seropositivity among men who have sex with men (MSM) and compare these to risk factors for anal and penile (HPV) deoxyribonucleic acid (DNA)-positivity in the same study population.
Methods: Seropositivity and anal and penile HPV DNA-positivity were determined for seven high-risk HPV genotypes for MSM aged 16-24 years participating in Papillomavirus Surveillance among STI clinic Youngsters in the Netherlands (PASSYON) 2009-2021. Logistic regression models were conducted to assess risk factors for seropositivity, anal and penile HPV DNA-positivity.
