BEXSERO: The only MenB vaccine with real world evidence demonstrated in a broad population[1-3]

BEXSERO has demonstrated an impact in reducing cases of meningococcal disease, helping to protect patients in a real life setting (national and regional immunisation programs).[1-2]

BEXSERO regional vaccination program in Saguenay-Lac-Saint-Jean (Quebec, Canada)1

  • From May through December 2014, an estimated 83% of 59,500 residents/individuals aged 2 months to 20 years was immunised in 2014 with BEXSERO in response to a MenB outbreak
  • In the four years following the vaccination campaign, serogroup B incidence fell by 96% from 11.4/100,000 (2006 to 2014) to 0.4/100,000 (2014 to 2018) (p<0.0001) in the targeted age group*

*Note during the assessment period MenB disease also decreased in the other regions where no vaccination took place; the magnitude of that decrease in younger and older age groups was over 50%. Taking into account the decrease in MenB incidence at provincial level, the overall campaign impact in the SLSJ was 86% [95% CI: -2%,98%]. The campaign impact was mostly seen in the target age-group suggesting no herd effect among unvaccinated older adults.

BEXSERO national immunisation program in the United Kingdom2

  • In September 2015, England offered BEXSERO to all infants free of charge, as part of a national immunisation program in the UK
  • In England, 92.5% (average annual birth cohort, approximately 650,000 infants) completed their primary immunisation by their first birthday, and 87.9% completed all 3 doses by 2 years
  • Using national surveillance data in England, it was determined MenB disease in all children fully eligible for vaccination was reduced by 75% (rate ratio: 0.25; 95% CI, 0.19 to 0.36) from September 2015 through August 2018
