Midwives' knowledge, attitudes and confidence in discussing maternal and childhood immunisation with parents: A national study

Maternal Vaccination and Vaccine Hesitancy

The American College of Obstetrics and Gynecology recommends influenza vaccine annually, Tdap with each pregnancy, and COVID-19 vaccine for those not previously vaccinated or who are due for boosters. The influenza and COVID-19 vaccines are safe during pregnancy and are effective in reducing morbidity in both the pregnant person and infant. The Tdap vaccine is given primarily to protect the newborn from pertussis through transplacental antibody transfer. Methods to enhance vaccination rates include stocking and giving vaccines in the obstetric office, recommending eligible vaccines at each visit, and focusing on the health of the infant in conversations with patients.

Vaccination in pregnancy: The role of the midwife

Midwives are the front-line workers providing maternity care for women in many countries. The role of the midwife includes providing information about, and recommendations for, maternal vaccination in pregnancy and for the baby in the postnatal period. Vaccinations recommended in pregnancy include those to prevent influenza, pertussis, tetanus and now COVID-19. Vaccinations for the newborn baby include hepatitis B. Healthcare professionals play an important role in influencing decision-making around vaccination and midwives are key in supporting vaccination uptake. Midwives are strong influencer in women's decisions around vaccination for themselves and their babies. The COVID-19 vaccination programs have shone a light on vaccination in pregnancy especially as SARS-COV-2 infection has significant adverse effects in pregnancy. COVID-19 vaccination has been shown to be safe and effective in pregnancy. Despite this, there is vaccine hesitancy from pregnant women in many countries. Midwives play a unique role in the provision of care to women and families but they need specific support and information regarding vaccination in pregnancy. Targeted education, supportive mentoring and supervision and opportunities to lead innovative ways of ensuring vaccine access is logistically easy and possible are all needed. This Commentary outlines the key vaccinations recommended in pregnancy including COVID-19 vaccination and highlights some strategies to scale-up vaccination programs in pregnancy with a particular focus on the role of midwives.

Understanding Barriers and Facilitators to Maternal Immunization: A Systematic Narrative Synthesis of the Published Literature

Introduction

Vaccines are being developed against Group B Streptococcus and respiratory syncytial virus. These vaccines are designed to be given to pregnant women to protect infants; thus, their success depends on uptake in this population. Maternal immunization programs have struggled to achieve target coverage rates. This systematic narrative synthesis aims to define the most important barriers and facilitators for maternal immunization and to identify priority areas for future research.

Methods

A search strategy was developed in Medline and adapted according to the requirements of additional search engines. Two reviewers independently reviewed the studies, using pre-specified inclusion and exclusion criteria. Results sections of included studies were coded, and thematic analysis was used to identify prominent themes.

Results

321 studies were included in the final review. Most studies came from North America (37%), Europe (26%) or East Asia, Australia and New Zealand (22%). Low-and middle-income countries were under-represented. Five percent of studies came from Sub-Saharan Africa, and 2% came from South Asia. The prominent factors impacting maternal immunization were provider recommendation, perceived risks and benefits of maternal vaccines for the infant, race, birthplace, and access to healthcare. Few studies explored reasons behind racial and socioeconomic disparities in maternal immunization rates.

Discussion

A strong provider recommendation, equitable access to prenatal care and messaging that focuses on vaccine safety and infant benefits emerged as the key components for optimising vaccine uptake among pregnant women. Research among healthcare providers, minority groups and in low- and-middle-income countries was lacking. In anticipation of the expansion of maternal immunization programmes, focused research is needed to address these gaps and inform a successful public health strategy.

COVID-19 vaccine hesitancy and patient self-advocacy: a statistical analysis of those who can and can't get vaccinated

Background

This study applies the Patient Self-Advocacy scale to investigate vaccine hesitancy in New Zealand. Due to New Zealand’s very limited tertiary hospital system and vulnerable populations, the Government’s strategy to address COVID-19 has been to prevent the virus from entering the nation and to eliminate it when it does cross the border. Therefore, there is no opportunity for the nation to generate any acquired immunity through exposure. To transition from closed borders, New Zealand will need to run a highly successful national vaccination programme and this needs to have the ability to drive influential public health messaging to the targeted places within the communities where vaccine hesitancy most exists.

Methods

This study employed statistical methods. A nationally representative survey of adults in New Zealand (n = 1852) was collected via Qualtrics. Independent samples t-tests, and multiple regression were used to explore the research questions.

Results

Those who identify as medically able to be vaccinated expressed significantly higher confidence in the COVID-19 vaccine than those who identified as unable to be vaccinated. Patient-self advocacy had a positive effect on vaccine confidence. Individuals who identify as able to be vaccinated have less hesitancy. Demographics had various effects on vaccine hesitancy.

Conclusion

The research highlights particularly important insights into vaccine hesitancy related to patient self-advocacy behaviours, and various demographic variables such as political affiliation. In addition, the research adds further clarity on how and why New Zealanders have responded to the COVID-vaccine. Finally, the importance of vaccine literacy is discussed.

Influences on Pregnant Women's and Health Care Professionals' Behaviour Regarding Maternal Vaccinations: A Qualitative Interview Study

The uptake of maternal influenza and pertussis vaccinations is often suboptimal. This study explores the factors influencing pregnant women's and health care professionals' (HCPs) behaviour regarding maternal vaccinations (MVs). Pregnant/recently pregnant women, midwives, pharmacists and general practice staff in Waikato, New Zealand, were interviewed. The analysis used the behaviour change wheel model. Interviews of 18 women and 35 HCPs revealed knowledge about MVs varied with knowledge deficiencies hindering the uptake, particularly for influenza vaccination. HCPs, especially midwives, were key in raising women's awareness of MVs. Experience with vaccinating, hospital work (for midwives) and training increased HCPs' knowledge and proactivity about MVs. A "woman's choice" philosophy saw midwives typically encouraging women to seek information and make their own decision. Women's decisions were generally based on knowledge, beliefs, HCPs' emphasis and their perceived risk, with little apparent influence from friends, family, or online or promotional material. General practice's concentration on children's vaccination and minimal antenatal contact limited proactivity with MVs. Busyness and prioritisation appeared to affect HCPs' proactivity. Multi-pronged interventions targeting HCPs and pregnant women and increasing MV access are needed. All HCPs seeing pregnant women should be well-informed about MVs, including how to identify and address women's questions or concerns about MVs to optimise uptake.
