MenB

Neisseria meningitidis (meningococcus) is a bacterium which causes meningitis and septicaemia. There are 13 serogroups of meningococcus, 6 (A, B, C, W, X and Y) cause most disease of which MenB is the most common cause of meningococcal disease in the UK. Infants have the highest incidence of MenB disease in the UK and across Europe, with the main burden of disease falling in the second 6 months of life.

In 2015 the UK became the first country in the world to introduce Men B vaccination with 4CMenB (Bexsero®) into its routine schedule, with a two-dose priming regime at 2 and 4 months with a booster at 12 months. The vaccine has proved to be very effective in preventing invasive MenB disease in immunised infants (Parikh et al, 2016). This study also showed that a single dose of 4CMenB however, was not effective. Half the MenB cases diagnosed after 16 weeks of age in the vaccine-eligible infant cohort were either unvaccinated or partially vaccinated (i.e. received only a single dose of 4CMenB). Such cases could potentially have been prevented through timely or, preferably, earlier completion of the primary immunisation schedule.

 

Current studies:

LION MenB study

This study is being undertaken to compare the immune responses of UK infants who receive their routine immunisations alongside two different 4CMenB primary immunisation schedules. Completing the primary 4CMenB schedule by 3 months could provide infants earlier protection against MenB disease since cases peak at 5 months of age and remain high in the second half of the first year before starting to decline.

If this clinical trial shows comparable immunogenicity for the main 4CMenB antigens using the two different schedules, then the results could change UK national immunisation policy to offer infants earlier protection against this devastating disease and could potentially be adopted by other countries worldwide.

Natalina Sutton

Natalina is currently a Clinical Research Fellow at St George’s Paediatric Infectious Diseases Research Group, working on COVID-19 and MenACWY vaccine studies. She has over a decades experience in child health in global settings. She has applied 6 years of experience as a foundation doctor and paediatric trainee to global public health work including, participation in mobile clinics to ensure access to healthcare for remote populations in Belize, and development of health promotion projects in Ecuador and Mexico. Natalina has a MSc in Public Health from the London School of Hygiene and Tropical Medicine and has carried out research projects on predicting IVIG resistance in Kawasaki Disease and prevention of childhood obesity in preschool children.

Paediatric Clinical Research Fellow

Zsofia Danos

Zsofia has been working in clinical paediatrics since 2014 and finished Paediatric training in November 2020. Zsofia started working for the paediatric infectious disease research group in September 2020. Her role as a clinical research fellow (currently mainly involved in the COVID-19 vaccine trials) includes recruitment and consenting of participants, reviewing medical history, vaccinating, conducting symptomatic reviews and covering on-call duties. Zsofia also works on the cChips CMV study and looking forward to be involved in other paediatric trials as well.

Project Manager

Polly Fox

I joined the PIDRG Team in September 2019 as a Project Officer working on a range of studies in RSV, fungal infections, AMR and vaccines. I’m now one of the Project Managers helping to deliver the COVID-19 Vaccine Trials we are running at St George’s as well as other Urgent Public Health studies such as a serological survey in children and young adults. I have also recently started an MSc Clinical Trials with LSHTM part-time to further my career development in trial coordination.
