2. Pro’s and Con’s of combined MenABCWY
vaccine vs separate immunisation
• Pro’s
• Potentially
• Simplifies immunisationschedules
• Reduces costs
• could make introduction of MenB into an
adolesecent schedule cost effective?
• Enhances uptake
• Reduces number of injections
• Reduces distress
• Cons
• Potentially
• Reduces flexibility*
• Reduces adaptability tolocal
epidemiology*
• Increases reactogenicity
• Reduces immunogenicity
• Increases risks of interference with
concomitantvaccines
* Dependent on whether MenABCWY would be licensed in addition to, or as a replacement for, existing meningococcalvaccines
Are likely to require a 2 dose schedule, so may not reduce number of immunisation episodes

3. Pfizer Studies combiningrlp-2086 (Trumenba) with MenACWY-CRM (Nimenrix)
Infant study (N = 1325) launchedNov 2020
No OMV - Less likely protective against gonococcus

4. Peterson et al, ID Week 2020
Healthy adolescents, approx50%
previously immunized with
MenACWY
Immunised with:
- Combined rlp-2086 and
MenACWY (MenABCWY) at a
0, 6 month interval
- MenACWY at 0 months and
rlp-2086 at0, 6 months
