A mixed methods approach to improving antenatal immunisation

Acknowledgements:
This research aims to identify how NHS maternity services can be supported to improve pertussis and other vaccination delivery to pregnant women, aiming to reduce inequities between demographic groups and NHS areas.
The MAVIS Study involves several projects designed to explore maternal vaccination in England, to identify what could be improved:
PROJECT 1: WHO IS MISSING OUT?
Retrospective cohort study using national primary care record data (CPRD) to explore predictors/risk factors for not being vaccinated in pregnancy - i.e. to describe the groups of women who are likely to miss out on their pregnancy vaccines. Collaborating with researchers at the London School of Hygeine and Tropical Medicine.
PROJECT 2: THE MATERNITY STAFF PERSPECTIVE
- Commissioner survey to map vaccination provision across all the maternity services/trusts in England
-
National survey with healthcare professionals at maternity services in NHS areas with the highest and lowest maternal pertussis vaccination coverage (aiming for 500 participants)
- In-depth interviews with healthcare professonals will supplement survey data
Project 2 has gained approval from the University of Bristol's Faculty of Health Science Research Ethics Committee (ref 9397)
PROJECT 3: THE PARENT PERSPECTIVE
** CURRENTLY RECRUITING! ** FOR MORE INFORMATION AND TO TAKE PART, VISIT: www.mavis-study.com
- Survey with recently pregnant women in NHS areas with the lowest maternal pertussis vaccination coverage - especially inviting those who did not receive a vaccination (aiming for 500 participants)
- In-depth interviews with recently pregnant women (and their partners) will supplement survey data.
Project 3 has gained approval from the HRA and Health and Care Research Wales and the London-Fulham Research Ethics Committee (ref 22/PR/1166)
PROJECT 4: RECOMMENDATIONS
Working with clinical and public advisory groups, the findings will be used to produce intervention recommendations to increase the number of pregnant women receiving the whooping cough vaccine across maternity services and demographic groups, and to inform other mother and child vaccine programmes.
PATIENT AND PUBLIC INVOLVEMENT (PPI)
- Parent advisory group (mothers from underserved communities and of Black/minoritised ethnicities)
