Vaccine coverage

Bexsero reactivity
none  caveats
Trumenba reactivity
cross-reactive  caveats

Bexsero Antigen Sequence Typing (1) was developed to allow high-throughput analysis of whole genome sequence data and cataloguing of vaccine antigenic variants.

  • There are 5 components to the BAST: fHbp, NHBA, NadA, PorAVR1 and PorAVR2.
  • Only 4 are used in determining the likelihood of coverage by the Bexsero vaccine:fHbp, NHBA, NadA, and PorAVR2. Of these, only fHbp and NadA variants are considered potentially cross-reactive.
  • You can find the BAST antigenic profile for this isolate by selecting the Typing → Bexsero Antigen Sequence Typing (BAST) link in the scheme tree at the bottom of the page.
  • Bexsero contains: fHbp 1; NHBA: 2; NadA 8; PorA VR2: 4.

The traffic light system was devised to help users of the BAST system to determine the potential genomic coverage of a given isolate by Bexsero.

  • isolate contains exact antigenic variants found in the vaccine.
  • isolate contains cross-reactive antigenic variants.
  • isolate contains no antigenic variants that are either exact matches or cross-reactive to those found in the vaccine.

It is important to understand the caveats to the estimates made using genomic data as below:

  • These are genomic estimates of vaccine coverage based on the presence or absence of genes encoding vaccine antigenic variants.
  • We have not inferred the cross-reactivity of antigenic variants based on genomic data alone.
  • We have used published literature to obtain information about cross reactivity of the antigens, which demonstrates that vaccinee sera can directly kill meningococci in serum bactericidal antibody assays or through the Meningococcal Antigen Typing System (MATS) assay (2,3), an indirect measure of the potential to be killed by vaccinees’ sera.
  • We have not inferred protein expression from the genomic data, therefore there may be isolates that possess genes but do not express the protein in vivo.
  • The age of the vaccinees included in the published trials needs to be considered when interpreting potential coverage of an isolate with Bexsero or Trumenba, and deciding which vaccine to administer.

Trumenba is a bivalent fHbp-containing vaccine.

  • The vaccine contains fHbp protein variants 45 and 55.

The traffic light system was devised to help users of PubMLST to determine the potential genomic coverage of a given isolate by Trumenba.
  • isolate contains exact antigenic variants found in the vaccine.
  • isolate contains cross-reactive antigenic variants.
  • isolate contains no antigenic variants that are either exact matches or cross-reactive to those found in the vaccine.
