Reassurance of population immunity to diphtheria in England: Results from a 2021 national serosurvey

CONCLUSIONS: Basic diphtheria protection is comparable between 2021 and 2009. The increase in immunity in working age adults is likely due to the school leaver booster introduced in 1994. The current vaccination schedule is maintaining sufficient population immunity. However, we recommend clinicians remain vigilant to severe diphtheria outcomes in older adults, because of their observed susceptibility.PMID:37821313 | DOI:10.1016/j.vaccine.2023.10.003
