Abstract
Respiratory Syncytial Virus poses a significant global public health threat, particularly affecting infants aged less than one year of age. Recently, two forms of passive immunization against infant RSV have been developed and brought to market; nirsevimab a long-acting monoclonal antibody (mAb) and RSV-PreF, a maternal RSV vaccine. The acceptability and uptake of these products will play a pivotal role in determining the success of any national immunization strategy aimed at safeguarding infants from RSV. It is crucial at this time to reflect on the factors that influence parental decisions surrounding immunization to facilitate more informed discussions, enhance healthcare communication, and contribute to the design of effective RSV prevention strategies that resonate with the concerns and aspirations of parents worldwide.

[PMID: 37741762 DOI: 10.1016/j.vaccine.2023.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/03/2023] [Accepted: 09/04/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND Respiratory infections including influenza and pertussis are associated with significant morbidity and mortality in mothers and newborns. Vaccination during pregnancy against influenza and pertussis is recommended for all women but data on uptake in Australia is limited. METHODS We conducted a retrospective population-based cohort study in Australia's largest state, New South Wales (NSW), using a Perinatal Data Collection (PDC). Data included demographic, pregnancy, and birth details including pertussis and influenza vaccination during pregnancy for all women giving birth between 01 January 2016 and 31 December 2020. We used descriptive statistics to assess uptake of influenza and pertussis vaccination during pregnancy and Poisson loglinear regression to estimate associations between maternal characteristics and vaccine receipt. RESULTS During 2016-2020, there were 477,776 births (mean maternal age 32.25 years). In 176,255 (36.9%) births the mother received both vaccines; 202,922 (42.5%) influenza and 315,620 (66.1%) pertussis vaccine. From 2016 to 2020, reported coverage increased from 26.7% to 58.7% for influenza and 43.1% to 78.8% for pertussis, respectively. After adjustment, characteristics associated with lower likelihood of receiving influenza and pertussis vaccination included: younger age (<30 years), being born in Australia/New Zealand, from lower socio-economic strata, having previous pregnancies, being later to first antenatal care, utilising the public hospital care model, smoking, having chronic hypertension and BMI > 25 kg/m2. CONCLUSIONS While reported coverage of both influenza and pertussis vaccine in birthing women in NSW has increased over time, disparities in coverage exist and they highlight areas where evidence-based interventions to improve maternal vaccination could be targeted.

Inequity of antenatal influenza and pertussis vaccine coverage in Australia: the Links2HealthierBubs record linkage cohort study, 2012-2017. BMC Pregnancy Childbirth 2023; 23:314.

Abstract
BACKGROUND Pregnancy and early infancy are increased risk periods for severe adverse effects of respiratory infections. Aboriginal and/or Torres Strait Islander (respectfully referred to as First Nations) women and children in Australia bear a disproportionately higher burden of respiratory diseases compared to non-Indigenous women and infants. Influenza vaccines and whooping cough (pertussis) vaccines are recommended and free in every Australian pregnancy to combat these infections. We aimed to assess the equity of influenza and/or pertussis vaccination in pregnancy for three priority groups in Australia: First Nations women; women from culturally and linguistically diverse (CALD) backgrounds; and women living in remote areas or socio-economic disadvantage. METHODS We conducted individual record linkage of Perinatal Data Collections with immunisation registers/databases between 2012 and 2017. Analysis included generalised linear mixed model, log-binomial regression with a random intercept for the unique maternal identifier to account for clustering, presented as prevalence ratios (PR) and 95% compatibility intervals (95%CI). RESULTS There were 445,590 individual women in the final cohort. Compared with other Australian women (n = 322,848), First Nations women (n = 29,181) were less likely to have received both recommended antenatal vaccines (PR 0.69, 95% CI 0.67-0.71) whereas women from CALD backgrounds (n = 93,561) were more likely to have (PR 1.16, 95% CI 1.10-1.13). Women living in remote areas were less likely to have received both vaccines (PR 0.75, 95% CI 0.72-0.78), and women living in the highest areas of advantage were more likely to have received both vaccines (PR 1.44, 95% CI 1.40-1.48). CONCLUSIONS Compared to other groups, First Nations Australian families, those living in remote areas and/or families from lower socio-economic backgrounds did not receive recommended vaccinations during pregnancy that are the benchmark of equitable healthcare. Addressing these barriers must remain a core priority for Australian health care systems and vaccine providers. An extension of this cohort is necessary to reassess these study findings.

J Genet Couns 2022; 31:1341-1348.

Abstract
Pregnant people are at increased risk of severe illness from SARS-CoV-2 infection and are more likely to be admitted to an intensive care unit, be put on a mechanical ventilator, and die, if infected. Having COVID-19 during pregnancy also increases the risk of preterm delivery. Vaccination is a critical tool for controlling the COVID-19 pandemic; however, to date, just over 30% of pregnant people in the United States have been vaccinated. It is important to identify any barriers to acceptance of the COVID-19 vaccine among the pregnant population so that specific hesitancy concerns can be addressed. Our objective was to identify the proportion of pregnant people who are unsure or not planning to be vaccinated against COVID-19 and collect information about their reasons for hesitancy. A questionnaire examining views on COVID-19 vaccine interest was administered to 299 pregnant people who contacted MotherToBaby 3/1/21-7/23/21. Questions obtained information about the perception of COVID-19 risk in pregnancy, interest in receiving a COVID-19 vaccine while pregnant, and reasons for acceptance or hesitancy. Within the sample, 21% had already been vaccinated against COVID-19, 43% were planning to get vaccinated, 9% were not planning to receive the vaccine, and 27% were undecided. Women who were not planning to get vaccinated and those that were undecided both said their concern was 'not enough safety information for pregnancy'. Individuals aged 18-25, those who made less than $50,000/year, and those who lived in the Northeast were more likely to be hesitant. Based on these data, continued efforts to collect and communicate high-quality and understandable information to pregnant people about vaccine safety should be a key priority in efforts to increase vaccine acceptance among this group.

Abstract
OBJECTIVES Population-specific studies of vaccine uptake in pregnancy are necessary to monitor progress and ensure enablers to vaccination are locally relevant. We aimed to determine the uptake of influenza and pertussis vaccine during pregnancy in women in south-east Queensland and the reasons why women were choosing not to vaccinate. METHODS A secondary analysis of data collected in a prospective cohort study. Data were collected at enrolment during pregnancy and within six weeks of giving birth. The primary outcome was the proportion of women vaccinated during pregnancy. RESULTS Among 310 pregnant women, 45.8% and 69.7% were vaccinated against influenza and pertussis, respectively; 123 (39.7%) had received both vaccines. The common predictor of vaccine uptake for influenza, pertussis or both was having had any vaccine in the 12 months prior to pregnancy. Not considering the vaccines necessary and perceptions of the risk of infection were common reasons for not intending to vaccinate. CONCLUSIONS Antenatal vaccine uptake remains suboptimal in women in south-east Queensland. Barriers to vaccination during pregnancy are complex and vary depending on context and population. Implications for public health: More efforts are needed to promote antenatal uptake, particularly for influenza vaccine and having both the influenza and pertussis vaccines during pregnancy.

Abstract
Vaccination in pregnancy (VIP) is dually beneficial - it protects the mother and the baby from tetanus, influenza, and pertussis. VIP uptake is low in many countries. Vaccine hesitancy, defined by the World Health Organization (WHO) as a "delay in acceptance or refusal of vaccination despite the availability of vaccination services" is one of WHO's ten threats to global health per 2019. According to extensive research, mostly from high-income countries (HIC) and limited to tetanus, influenza and pertussis vaccines, lack of provider recommendations, safety concerns, and limitations in access are the main barriers to VIP. Health care provider recommendation is the leading facilitator for VIP across various socioeconomic status groups. Data on strategies to overcome patient, provider, and system barriers to VIP are inconsistent, contradictory, or lacking. Patient-focused research on evidence-based strategies to overcome provider and system barriers is needed. Furthermore, VIP programs require embedded continuous quality improvement to ensure sustainability.

Abstract
About 12.5% of all maternal deaths in the United States are due to infectious causes. This proportion, although stable during the past three decades, represents an increase in infectious causes of mortality, as the overall mortality rate in U.S. pregnant women had increased steadily during that same period. During healthy pregnancies, a delicate immunological balance-in which a mother's immune system tolerates the semi-allogeneic fetus yet maintains immune competency against infectious agents-is achieved and maintained. This immunological paradigm, however, results in increased susceptibility to infectious diseases during pregnancy, particularly in later stages and during the early postpartum period. The inflammatory process induced by these infectious insults, as well as some noninfectious insults, occurring during pregnancy can disrupt this carefully achieved balance and, in turn, lead to a state of rampant inflammation, immune activation, and dysregulation with deleterious health outcomes for the mother and fetus. Elucidating mechanisms contributing to the disruption of this immunologic homeostasis, and its disruption by infectious pathogens, might offer opportunities for interventions to reduce maternal and fetal morbidity and mortality.

Abstract
Group B Streptococcus, a common commensal in the gut of humans and in the lower genital tract in women, remains an important cause of neonatal mortality and morbidity. The incidence of early onset disease has fallen markedly in countries that test women for carriage at 35-37 weeks of pregnancy and then offer intrapartum prophylaxis with penicillin during labour. Countries that do not test, but instead employ a risk factor approach, have not seen a similar fall. There are concerns about the effect on the neonatal microbiome of widespread use of antibiotic prophylaxis during labour, but so far the effects seem minor and temporary. Vaccination against GBS would be acceptable to most women and GBS vaccines are in the early stages of development. Tweetable abstract: Group B Strep is a key cause of infection, death and disability in young babies. Antibiotics given in labour remain the mainstay of prevention, until a vaccine is available.
