A comprehensive systematic review and meta-analysis by the Infectious Disease Epidemiology Group examined the epidemiology of Chlamydia trachomatis in Canada & analyzed data spanning more than four decades (1981–2025), providing important insights into infection prevalence, risk patterns, and public health implications. The findings highlight the continued burden of chlamydia and reinforce the need for strengthened screening, prevention strategies, and investment in vaccine development.

A new study by our Infectious Disease Epidemiology Group in collaboration with the Biolab Diagnostic Laboratories in Jordan, provides one of the first comprehensive assessments of the epidemiology of Neisseria gonorrhoeae (gonorrhea) in Jordan using a national laboratory dataset spanning 2014 to 2025.

Analyzing data from 8,779 individuals, the study found a low overall prevalence and incidence of gonorrhea in Jordan. However, higher positivity rates among individuals tested for clinical reasons, coupled with no evidence of a temporal decline in infections, suggest ongoing transmission that warrants continued public health attention.

The findings underscore the importance of strengthening surveillance systems, expanding targeted testing and treatment strategies, and incorporating antimicrobial resistance monitoring to better inform prevention and control efforts.

A new study demonstrates how a novel fatty acid measurement derived from NMR lipoprotein profiling can uncover genetic signals linked to fatty acid metabolism.
Analyzing data from over 274,000 participants in the UK Biobank, researchers identified key genetic pathways involved in lipid regulation, providing a valuable new tool for understanding cardiovascular and metabolic health.
Congratulations to the research team, Dr. Abdelaziz Belkadi, Dr. Gaurav Tharja, Nisha Stephan, Dr. Anna Halama and Dr. Karsten Suhre on this important publication in the Journal of Proteome Research.

New publication in iScience
Researchers from the Ca²⁺ Signaling Group have identified a previously unknown endoplasmic reticulum structure, the cER-basket, that plays a critical role in regulating intracellular calcium signaling. Using a combination of 3D ultrastructural reconstruction, mathematical modeling, and experimental validation, the team demonstrates how this specialized cellular architecture supports calcium tunneling and shapes signaling dynamics. The findings provide new insights into how cellular structure influences signaling specificity and function, advancing our understanding of fundamental mechanisms that govern cell behavior.
Congratulations to Dr. Raphael Courjaret, Dr. Khaled Machaca, and colleagues on this important contribution to cell biology and calcium signaling research.

📢 New Editorial Published in Expert Review of Vaccines

Aggregate analyses can sometimes obscure important temporal and dose-specific safety signals.
In this new editorial, the Infectious Disease Epidemiology Group (IDEG) demonstrates how stratified self-controlled case series (SCCS) analyses can provide deeper insight into vaccine safety by examining shorter risk windows, stroke subtypes, and vaccine dose number.
🔬 A reanalysis of stroke following COVID-19 mRNA vaccination in Qatar found that the overall signal was concentrated in the first week after vaccination and was largely driven by the first vaccine dose.
Importantly, these findings do not establish causality. Rather, they illustrate how refined SCCS analyses can uncover nuanced, hypothesis-generating patterns that may be missed by conventional aggregate approaches.
📊 The work highlights the value of incorporating clinically informed stratification into vaccine safety SCCS studies while interpreting newly identified signals cautiously and validating them through further analyses.
Congratulations to and colleagues in the IDEG group on this important methodological contribution to vaccine safety research.

A future HSV-1 vaccine could help reshape the burden of herpes infections.

📢A new study by our IDEG, published in , uses mathematical modeling to estimate the projected public health benefits of a hypothetical HSV-1 vaccine in the United States.
The findings indicate that vaccination could substantially reduce both oral HSV-1 and ge***al HSV-1 infections, with the greatest projected benefit seen when protection is lifelong and vaccination includes adolescent catch-up.
These findings highlight the potential value of advancing HSV vaccine development and integrating future vaccines into public health strategies.

Congratulations to our IDEG team members, Drs. Laith Abu-Raddad, Bechir Naffeti and Houssein H. Ayoub, and to collaborator Christine Johnston for their important contributions to this work.

A new study led by researchers from Weill Cornell Medicine-Qatar, in collaboration with Hamad Medical Corporation (HMC), the Ministry of Public Health (MOPH), and QRDI, found that the "healthy vaccinee effect" did not measurably bias COVID-19 vaccine effectiveness estimates.
Using national population-level data, the study showed that although vaccinated individuals generally had better underlying health than unvaccinated individuals, vaccine effectiveness estimates against infection and severe COVID-19 remained remarkably consistent across different analytical approaches.
These findings strengthen confidence in real-world vaccine effectiveness studies and highlight the importance of using rigorous, well-defined clinical outcomes in public health research.
