“…Recently, there has been a reported 21.7% uptake of maternal influenza vaccine and 25.7% uptake of maternal pertussis vaccine among 323 622 pregnant women from New Zealand between 2013 and 2018. 17 Women who received the two-dose vaccine had higher rates of elective CDs with similar rates of in-labour CD. This could be attributed to the higher rates of previous CDs among this group, which itself is a risk factor for CD in a subsequent delivery.…”

Objective To evaluate the impact of Covid‐19 vaccination (Pfizer–BioNTech BNT162b2) during the third trimester of pregnancy on maternal and neonatal outcomes. Design A multicentre, retrospective computerised database. Population Women who gave birth at >24 weeks of gestation in Israel, between January and April 2021, with full records of Covid‐19 disease and vaccination status. Methods Women who received two doses of the vaccine were compared with unvaccinated women. Women who were recorded as having disease or a positive Covid‐19 polymerase chain reaction (PCR) swab during pregnancy or delivery were excluded from both study groups. Univariate analysis was followed by multivariate logistic regression. Main outcome measures Composite adverse maternal outcomes. Secondary outcomes were vaccination rate and composite adverse neonatal outcomes. Results The overall uptake of one or both vaccines was 40.2%; 712 women who received two doses of the Covid‐19 vaccine were compared with 1063 unvaccinated women. Maternal composite outcomes were comparable between the groups; however, women who received the vaccine had higher rates of elective caesarean deliveries (CDs) and lower rates of vacuum deliveries. An adjusted multivariable logistic regression analysis demonstrated that Covid‐19 vaccination was not associated with maternal composite adverse outcome (aOR 0.8, 95% CI 0.61–1.03); a significant reduction in the risk for neonatal composite adverse outcomes was observed (aOR 0.5, 95% CI 0.36–0.74). Conclusions In a motivated population covered by a National Health Insurance Plan, we found a 40.2% rate of vaccination for the Covid‐19 vaccine during the third trimester of pregnancy, which was not associated with adverse maternal outcomes and, moreover, decreased the risk for neonatal adverse outcomes. Tweetable abstract Covid‐19 vaccine during pregnancy is safe for both mother and fetus.

“…In America, the rate was 61.2% during the 2019/2020 season (20), which was lower than the Healthy People 2020 target of 80% (21). In New Zealand, only 21.7% of pregnant women received influenza vaccines from 2013 to 2018 (22). The global influenza vaccination coverage warrants to be vigorously improved in the future, particularly during the COVID-19 pandemic period.…”

Comparison of Vaccine Acceptance Between COVID-19 and Seasonal Influenza Among Women in China: A National Online Survey Based on Health Belief Model

2021

Background: Influenza could circulate in parallel with COVID-19. Studies focusing on the comparison of vaccine acceptance between COVID-19 and seasonal influenza are lacking. The aim of the study was to assess and compare vaccine acceptance of COVID-19 and influenza among reproductive women in China, in order to better understand and address factors associated with vaccine acceptance and to provide guidance for targeted measures to promote vaccination.Methods: A national anonymous cross-sectional survey on COVID-19 and influenza vaccine acceptance among reproductive women aged 18–49 years in China was conducted online based on health belief model, a model widely used to evaluate health beliefs. Sociodemographic characteristics, health status, knowledge, attitude, and health beliefs related to COVID-19 and influenza infection and vaccination were retrieved. Pearson's χ2 test was used to compare the vaccine acceptance by the factors mentioned above. Multivariable logistic regression was used to assess the adjusted associations of factors related to vaccine acceptance. Paired t-test was used to compare scores of health beliefs between influenza and COVID-19 vaccinations.Results: COVID-19 vaccine acceptance rate among reproductive women was 90.3% (95% CI 89.2–91.3%), which was significantly higher than influenza vaccine acceptance rate (85.5%, 95% CI: 84.2–86.7%). Influenza and COVID-19 vaccine acceptance both had the trends to decrease with age (all p < 0.05). Living in the western region, young age, a high level of knowledge scores on disease and vaccines, a high level of perceived susceptibility, a high level of cues to action, and a low level of perceived barriers were positively associated with both COVID-19 and influenza vaccine acceptance (all p < 0.05), while influenza vaccination history was additionally associated with influenza vaccine acceptance (p < 0.05).Conclusions: Our findings suggest that tailored public health measures are needed to improve reproductive women's knowledge of COVID-19, influenza, and vaccines to alleviate women's vaccine hesitancy and expand vaccine uptake.

“…The uptake of maternal vaccinations (MVs) is suboptimal in many countries [11][12][13][14], particularly among those experiencing greater socioeconomic deprivation [15,16] and among indigenous people and people born overseas [16,17]. Lack of awareness, misperceptions, safety concerns and access challenges hinder maternal vaccine uptake [14,[18][19][20][21][22][23][24][25].…”

“…In New Zealand (NZ), maternal influenza vaccination uptake in 2018 was 31% and maternal pertussis vaccination uptake was 44% [16]. While steadily increasing, the uptake remains suboptimal, and is particularly low for Māori (indigenous people in NZ) and Pacific peoples, those living in more deprived circumstances and for younger women.…”

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.
