MenB vaccination coverage higher in those receiving MenB-4C

While meningococcal group B (MenB) vaccination remains suboptimal in the United States, completion was significantly higher for the MenB-4C (Bexsero) vaccine, compared with the other vaccine option, MenB-FHbp (Trumenba), according to Elizabeth Packnett of IBM Watson Health in Bethesda, Md., and associates.

In a study published in Vaccine, the investigators retrospectively analyzed 65,205 (36,118 received MenB-4C; 29,087 received MenB-FHbp) commercially insured individuals from the MarketScan Commercial Claims and Encounters Database during Jan. 1, 2015–Feb. 28, 2018, as well as 13,535 (10,153 received MenB-4C; 3,382 received MenB-FHbp) Medicaid-covered individuals from the Medicaid Multi-State Database during Jan. 1, 2015–Dec. 31, 2017.

The rate of vaccine completion in the MarketScan database within 15 months of initiation was 63% for MenB-4C and 52% for MenB-FHbp, and dosing schedule adherence was 62% for MenB-4C and 18% for MenB-FHbp. The median time to completion among those who finished vaccination was 68 days for MenB-4C versus 258 days for MenB-FHbp.

In the Medicaid database, the rate of vaccine completion within 15 months of initiation was 49% for MenB-4C and 31% for MenB-FHbp; dosing schedule adherence was 48% and 8%, respectively. Median time to vaccine completion was 88 days for MenB-4C versus 309 days for MenB-FHbp.

“The observations of improved completion and schedule adherence rates for MenB-4C, compared with MenB-FHbp, were consistent across both the commercial and Medicaid populations, and persisted after adjusting for individual factors in multivariable analyses, suggesting that the results were not skewed by population differences in demographic or other characteristics,” the investigators noted, adding that the significant difference in completion and schedule adherence between vaccines likely reflects the MenB-4C flexible dosing schedule.

The study was funded by GlaxoSmithKline, the maker of MenB-4C, and four coauthors reported being employed by the company. Five coauthors were employed by IBM Watson Health, which conducted the study.
