Implications of suboptimal measles immunity in UK health-care workers. Lancet. 2024 Jul 6;404(10447):23-24. doi: 10.1016/S0140-6736(24)01011-0.1474-547X10.1016/S0140-6736(24)01011-038944048http://hdl.handle.net/20.500.14200/5042The UK Health Security Agency declared the rapid increase in measles cases a national incident on Jan 19, 2024.1 We found in two cohorts of UK health-care workers that measles immunity is currently suboptimal. The VIBRANT study, which was a substudy of the national UK SIREN study,2 examined the immune system of 200 health-care workers recruited from NHS hospitals across the UK (cohort 1; median age 51 years [IQR 42–58], 161 [81%] were female and 39 [19%] were male). Of these 200 participants, six (3%) were negative for the measles antibody and eight (4%) had equivocal resultsenCommunicable diseasesMicrobiology. ImmunologyPublic health. Health statistics.
