On 15^th May 2024, Medical Research Council Unit The Gambia at the London School of Hygiene and Tropical Medicine (MRCG at the LSHTM), organised an open day in Sukuta. In collaboration with Sukuta Health Centre, it brought together parents, community leaders, local government authorities to share the findings of the phase 3 clinical trial of the Maternal Immunisation Study for Safety and Efficacy (MATISSE). Funded by Pfizer, the Maternal Respiratory Syncytial Virus (RSV) vaccine which has already been licensed by the United States Food and Drug Administration, offers a promising future to reducing mother to child infection of RSV.

The MATISSE study focused on immunising pregnant women against RSV to reduce its severity in infants. The trial recruited women between 24 and 36 weeks of gestation. Out of the over 200 pregnant women who participated in the study,196 were vaccinated.

Speaking at the open day, Claire Oluwalana, Clinical Trial Coordinator of the RSV Study, acknowledged the study’s significance, stating that, “vaccinating mothers in pregnancy for such vaccines like tetanus toxoid, pertussis, and recently, the RSV vaccine protects babies immediately after birth and within the early months of life, when the risk of death is highest.”

Dr Jane Maina, World Health Organisation Representative in The Gambia emphasised the importance of the study to newborns. “Ensuring that every mother receives the best protection through scientifically backed healthcare provisions and vaccines, is crucial for them and their newborns” she said.

“MRCG’s collaboration with the Ministry of Health, demonstrates that The Gambia is taking significant steps towards enhancing maternal health through innovation, a commitment to advance” Dr Maina concluded.

The Unit works closely with the Ministry of Health and regional health facilities to strengthen vaccine effectiveness and use as part of efforts to improve infant health.

Addressing the gathering, Musa Camara, Regional Health Director for West Coast Region, representing the Director of Health Services at the Ministry of Health, recognised MRCG’s significant contribution to vaccine trials in The Gambia highlighting that “MRCG has been an important partner to the Ministry of Health. We recognise that sustainable development cannot be attained if populations are not healthy and our partnership with MRCG is crucial to achieve this.”

Fatou Darboe, a mother who spoke on behalf of the beneficiaries’ thanked stakeholders, including parents, community members, leaders, healthcare professionals, and research collaborators acknowledging their crucial role to the successful completion of the project.

The MATISSE study conducted across 18 countries around the world, tested the efficacy of the RSVpreF (bivalent RSV prefusion F protein-based) vaccine. It seeks to explore the possibility of reducing the severity of RSV in infants through the vaccination of pregnant women.

MRCG’s lead role in the study in The Gambia demonstrates our continued commitment to save lives and advance medical research.
