Yellow fever vaccination coverage heterogeneities in Luanda province, Angola

In either event, a substantial portion of the truly susceptible population is likely to remain at risk owing to overvaccination in some districts and undervaccination in others.1 In view of the current global yellow fever vaccine shortage, undervaccinated districts in Luanda province are unlikely to achieve 100% vaccination.8 These districts might continue to experience sustained transmission, thus increasing the likelihood of exportation events to other countries. [...]in low-supply settings, our findings suggest that smaller-scale (eg, district-level) coverage heterogeneities--as opposed to larger scale (eg, province-level) vaccination rates--should be carefully considered when developing and monitoring vaccine allocation strategies.
