What does this research mean for the field?

Documented receipt of a 2-dose measles-containing vaccine alone may not be sufficient proof of measles immunity in healthcare workers, as a substantial proportion of measles-infected healthcare workers had received two or more doses. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

What question did this study set out to answer?

To assess whether documented receipt of two measles vaccine doses reliably indicates immunity by evaluating vaccination rates among healthcare workers who contracted measles.

Systematic review reveals 28% of measles-infected healthcare workers received two vaccine doses, suggesting proof of vaccination alone may not guarantee immunity.

Key Points

To assess whether documented receipt of two measles vaccine doses reliably indicates immunity by evaluating vaccination rates among healthcare workers who contracted measles.
Searched PubMed, Embase, and Scopus databases for studies published between 1974 and 2019 reporting measles infections in healthcare workers.
Performed a prevalence meta-analysis and meta-regression across 27 studies (N=1,319 measles-infected healthcare workers, aged 18–60 years) using time elapsed since national immunization schedule inclusion as a moderator.
Among infected healthcare workers, 28.0% (95% CI: 11.0 to 46.0) had received ≥2 vaccine doses, 41.0% (95% CI: 28.0 to 55.0) had received ≥1 dose, and 31.0% (95% CI: 17.0 to 46.0) were unvaccinated.
Infections occurred predominantly in females at 65.0% (95% CI: 57.0 to 72.0), individuals born after national vaccine introduction at 77.0% (95% CI: 66.0 to 87.0), nurses at 31.0% (95% CI: 24.0 to 39.0), and doctors at 27.0% (95% CI: 19.0 to 36.0).
Measles risk in healthcare workers who received ≥2 vaccine doses significantly increased with the duration elapsed since vaccine introduction into national immunization schedules (p < 0.05).
