Pregnant women are a priority group for COVID-19 vaccination due to their vulnerability as a high-risk cohort. However, the currentCOVID-19 vaccine uptake rate for COVID-19 vaccination among pregnant women in Western Australia remains largely unknown.

Influenza and COVID-19 infections during pregnancy may have serious adverse consequences for women as well as their infants. However, uptake of influenza and COVID-19 vaccines during pregnancy remains suboptimal. This study aims to assess the effectiveness of a multi-component nudge intervention to improve influenza and COVID-19 vaccine uptake among pregnant women. 

Vaccination in pregnancy is the best strategy to reduce complications from influenza or pertussis infection in infants who are too young to be protected directly from vaccination. Pregnant women are also at risk of influenza complications preventable through antenatal vaccination. Both vaccines are funded under the National Immunisation Program for pregnant women in Australia, but coverage is not routinely reported nationally. 

Vaccine hesitancy and suboptimal vaccine uptake pose significant threats to public health, but modifiable psychological factors underpinning them are under-investigated. We examined the prevalence of spontaneous emotional mental imagery relating to infectious diseases and perinatal vaccines and its unique associations with vaccine hesitancy and uptake behaviour.

A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.

Maternal influenza and pertussis vaccination is an important strategy to reduce morbidity and mortality in infants. Previous vaccine safety studies have mostly focused on the association between maternal vaccination and fetal death.

Maternal immune activation and prenatal maternal stress are well-studied risk factors for psychiatric conditions such as autism and schizophrenia. Animal studies have proposed the gut microbiome as a mechanism underlying this association and have found that risk factor-related gut microbiome alterations persist in the adult offspring.

It is unclear whether sex differences in behavior arising from birth weight (BW) are genuine because of the cross-sectional nature and potential confounding in previous studies. We aimed to test whether sex differences associated with BW phenotype were reproducible using a Mendelian randomization approach, i.e., association between polygenic score (PGS) for BW and behavior outcomes across childhood and adolescence. 

Consumption of a Mediterranean diet (MD) has been associated with reduced incidence of non-communicable diseases and reduced overall mortality, with epigenomic effects representing plausible mediators. The aim of this pilot study was to explore potential epigenetic associations between DNA methylation markers in blood and adherence to an MD in pregnancy.

Diabetes in pregnancy is associated with increased risk of long-term metabolic disease in the offspring, potentially mediated by in utero epigenetic variation. Previously, we identified multiple differentially methylated single CpG sites in offspring of women with gestational diabetes mellitus, but whether stretches of differentially methylated regions can also be identified in adolescent GDM offspring is unknown.
