The problem
Intervention: Analysis of population immunity against measles through serological testing to identify immunity gaps
Who it was tested with: 56,360 diagnostic samples from 50,754 individuals in Austria, stratified by birth year from 1922 to 2024.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"we analysed if immunity recently declined due to the COVID-19 pandemic, vaccine-induced immunity waned over long term or immunity gaps already pre-existed in the population" and "we determined anti-MeV antibody levels in a retrospective dataset of 56,360 diagnostic samples (from 50,754 individuals) collected 2010-2024". This is a descriptive surveillance study that documents immunity patterns but does not evaluate an intervention to improve measles immunity.
Retrospective diagnostic dataset may not represent general population; cannot determine causation of immunity gaps; does not assess actual outbreak attack rates or intervention effectiveness
