What is the death rate from measles in the UK for unvaccinated kids?
No record here gives a UK death rate for unvaccinated children. The closest numbers are from other countries, and they range from under 1 in 100 to about 5 in 100.
The honest answer is that this retrieval cannot give you a UK figure. It surfaced no UK surveillance data, no UK outbreak series, and no UK community study of measles deaths in unvaccinated children. What it does give is the range of case fatality rates seen elsewhere, and that range is wide enough that quoting any single number as "the" UK rate would be invention.
| Setting | Deaths per 100 measles cases |
|---|---|
| Romania outbreak, 2016-19 [3] | 0.4 |
| Pakistan outbreak, unvaccinated children [2] | 0.68 |
| Nationally representative community studies [1] | 1.0 (median) |
| Rural community studies [1] | 5.06 (median) |
| All community studies pooled [1] | 3.29 overall |
The pattern matters more than any single row. Death rates were higher in rural settings, in outbreaks, and in children under five [1]. In Romania, 45 of the 64 deaths were in unvaccinated children aged one year or under [3]. That is the group where measles is most lethal, and it is the group too young to be vaccinated on schedule.
What this retrieval cannot see is the UK specifically. UK measles deaths in the vaccine era are rare enough that a single outbreak series would be needed to estimate a rate, and none was surfaced. The absence is a fact about this search, not a finding about Britain.
My call: the UK-specific death rate for unvaccinated children is not established by this evidence; the best available range from comparable settings is roughly 0.4 to 5 deaths per 100 cases, concentrated in infants and the malnourished. Confidence: low on any UK number, moderate on the range.

Estimates of measles case fatality ratios: a comprehensive review of community-based studies
In a comprehensive review of community-based measles studies, CFRs varied widely (median 3.91%), were higher in rural, outbreak, under-5, and unvaccinated populations, and remained too imprecise for reliable global extrapolation.

Characterisation of measles after the introduction of the combined measles-mumps-rubella (MMR) vaccine in 2004 with focus on the laboratory data, 2016 to 2019 outbreak, Romania
During Romania's 2016-2019 measles outbreak, 17,533 cases and 64 deaths occurred, mostly in unvaccinated individuals, with genotype B3 predominant (n=269) and D8 sporadic (n=9), indicating multiple virus importations and insufficient MMR coverage.
