Our results show that inequalities in infection risk between ethnic groups are context- and pathogen-dependent, so public health interventions based only on national-level estimates would conceal regional variation in risk and may ultimately increase inequalities. 🚨Not yet peer reviewed🚨

Alexis Robert @alxsrobert.bsky.social · 21/04/2026

This, together with mixing patterns and demographic differences, led to inequalities in simulated transmission dynamic. Differences in ethnic composition and population structure between cities in England resulted in differences in expected inequalities at a local level. 🚨Not yet peer reviewed🚨

We used the largest social contact survey available in England (Reconnect, see here www.medrxiv.org/content/10.1...), and found that differences in contact distribution between ethnic groups remained after adjusting for demographic variables.

In England, the burden of respiratory infections varies by ethnicity. Many factors lead to observed disparities. We show that differences in demographic characteristics, mixing patterns, and distribution of contacts between ethnic groups all create inequalities in infection risks

In itself, the simulation model showed that an early delivery of MMR2 has the potential to reduce the risk of large measles outbreaks. Improving coverage remains the best way to fully mitigate outbreak risk.

010

Alexis Robert @alxsrobert.bsky.social · 13/10/2025

Across scenarios and sensitivity analyses, bringing MMR2 forward led to a short- and medium-term reduction in case numbers in the simulations. This decrease was impacted by coverage: if MMR2 coverage decreased by 3-5% in the new schedule, only 4.8% of cases were averted.

100

Alexis Robert @alxsrobert.bsky.social · 13/10/2025

Vaccine-induced immunity did not wane in the reference scenario. When a slow waning was included (from our previous study www.thelancet.com/journals/lan...), the impact of early MMR2 delivery decreased slightly (5.28% reduction). If waning started at a younger age, the reduction dropped to 3.79%.

Number of measles cases and cases avoided by vaccination strategy using a model including waning since vaccination.

100

Alexis Robert @alxsrobert.bsky.social · 13/10/2025

The different vaccination strategies changed the age distribution of the cases: an earlier delivery of MMR2 led to a lower proportion of measles cases in children aged between 2 and 4. A 0.5% increase of MMR1 uptake decreased the number of measles cases across all age groups.

Comparison of measles cases per age compartment as proportion of all cases and absolute numbers of cases between the reference scenario and an earlier MMR2 (A, D), between the reference scenario and MMR1 improved by 0.5% (B, E) and MMR2 given at the age of five (C, F). The error bars represent the interquartile range across all 2500 simulations per scenario.

100

Alexis Robert @alxsrobert.bsky.social · 13/10/2025

We used a compartmental model stratified by age and region, and simulated outbreaks with different vaccination schedules and coverage. Without changes to coverage, moving MMR2 to 2 years reduced the number of cases by 11.86%, similar to increasing MMR1 coverage by 0.5% across all regions and years.

Comparing the median number and IQR (shaded area) of simulated cases across simulations using CPRD data between A Reference scenario and MM2 given at school age, B Reference scenario and MMR2 given at the age of two, C MMR2 given at the age two against an increase of MMR1 by 1%, D increased MMR1 by 1% and an earlier MMR2 with the same coverage as MMR1. E, F are comparing the early MMR2 with the same uptake as before against a drop in coverage by 3% and 5% respectively.

100

Alexis Robert @alxsrobert.bsky.social · 13/10/2025

Changes in the vaccination schedule affect transmission: it may impact vaccine coverage, and close an immunity gap by quickly protecting children who did not react to the first dose, but it also requires an extra vaccination appointment. This may be difficult for parents, and lead to lower coverage.
