In a retrospective study, we analyzed the immune status of 1134 travellers (621 males, 513 females), by comparing actual with recommended vaccinations, in particular with regard to malaria. 61.6% of travellers showed complete immunization against diphtheria, 73.3% against tetanus, and 66.3% against polio. Overall, women have better immunization rates than men. The best immunization rates were seen in young adults (< 20 years). The majority of travellers had destinations in Africa (35.2%), Asia (21.95) and South America (20.9%). Accordingly, vaccinations for yellow fever and hepatitis were the most commonly indicated and implemented vaccinations, and more than 50% received antimalarial chemoprophylaxis.

Targeting PCSK9, through an innovative cVLP-based vaccine, enhanced the therapeutic activity of a cVLP-HER2 vaccine in a preclinical model of HER2-positive mammary carcinoma.

Background: HER2-targeted therapies have revolutionized the treatment of HER2-positive breast cancer patients, leading to significant improvements in tumor response rates and survival. However, resistance and incomplete response remain considerable challenges. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition is a novel therapeutic strategy for the management of dyslipidemia by enhancing the clearance of low-density lipoprotein cholesterol receptors, however recent evidence also shows links between PCSK9 and cancer cells.

Background: Multiple studies have demonstrated that the abundance and functionality of γδ T cells are favorable prognostic indicators for prolonged survival in cancer patients. However, the association between the immunophenotype of circulating γδ T cells and the therapeutic response in NSCLC patients undergoing chemotherapy or targeted therapy remains unclear.
Methods: Patients with EGFR wild-type (EGFR-WT) or mutant (EGFR-Mut) non-small cell lung cancer (NSCLC), diagnosed between January 2020 and January 2024, were included in this study.
The association of public health interventions regarding both infant sleep position and pertussis immunization with sudden infant death syndrome rates: an ecological study.

Institute of Social Medicine, Epidemiology and Health Economics, Charité - Universitätsmedizin Berlin, Luisenstr. 57, 10117, Berlin, Germany.
Background: Infections may play a role in the etiology of sudden infant death syndrome (SIDS), with Bordetella pertussis being a potential agent. The objective was to analyze the association of SIDS and infant pertussis hospitalization rates over time, comparing a previously unvaccinated population (West Germany) versus a predominantly vaccinated population (East Germany).
Methods: We calculated SIDS rates per 1000 live births per state.
Impact of vaccination against SARS-CoV-2 on mortality risk, ICU admission rate, and hospitalization length in hospitalized COVID-19 patients: a cross-sectional study.

Background: Vaccination against SARS-CoV-2 has been crucial in impeding virus spread and preventing fatal complications. Despite growing evidence of vaccine efficacy, data on its impact on hospitalized patients remain limited. We aimed to estimate the risk of mortality, ICU admission, and hospitalization length among hospitalized COVID-19 patients based on vaccination status.

Glioblastoma (GBM) is a primary central nervous system neoplasm, characterized by a grim prognosis and low survival rates. This unfavorable therapeutic outcome is partially attributed to the inadequate immune infiltration and an immunosuppressive microenvironment, which compromises the effectiveness of conventional radiotherapy and chemotherapy. To this end, precise modulation of cellular dynamics in the immune system has emerged as a promising approach for therapeutic intervention.
