Surveillance and vaccine effectiveness of pertussis, the Netherlands, 2012 to 2024, with an unprecedented surge in 2023 and 2024.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUNDA surge in pertussis occurred in the Netherlands in 2023-24. Infant vaccination uptake decreased from 95% in 2011 to ca 86% in 2024. Maternal vaccination was introduced in 2019, with uptake ca 70%.AIMTo describe pertussis epidemiological trends in the Netherlands.METHODSWe conducted a retrospective study using pertussis notification data from 2012 to 2024 and estimated infant and maternal vaccine effectiveness (VE) with the screening method.RESULTSDuring the COVID-19 pandemic, pertussis notifications dropped from ca 6,000 in 2013-19 to 79 in 2021 (incidence ca 35 to < 0.01/100,000 population). Notifications surged from May 2023, peaking in March 2024, resulting in 18,208 notifications in 2024 (102/100,000). Notifications and hospitalisations in 2024 were highest among infants aged 0-5 months (573 and 304/100,000) followed by infants aged 6-11 months (446 and 92/100,000). Annually, 0-2 deaths were reported; in 2023-24, 10 deaths were reported (6 infants, 4 ≥ 60-year-olds). In 2024, 83% of mothers of notified infants aged 0-2 months were unvaccinated. In 2020-24, maternal VE against pertussis in infants aged 0-2 months was 91%. In 2012-24 primary series VE was 98% at age 1, 92% at age 3, 92% post-booster at age 5, and 71% at age 9 years.CONCLUSIONLow population immunity after 2 years of reduced circulation likely contributed to the highest pertussis incidence ever recorded in the Netherlands, posing a particular threat to unprotected infants. Maternal and infant VE are high, underscoring the public health priority of enhancing vaccination uptake.
