COVID-19 vaccination in pregnant and lactating diabetic women

COVID-19 Vaccine Acceptance Among Pregnant, Lactating, and Nonpregnant Women of Reproductive Age in Turkey: A Cross-Sectional Analytical Study

OBJECTIVE

This study aims to identify the rates of coronavirus disease 2019 (COVID-19) vaccine acceptance, the reasons for receiving and not receiving the vaccine, and the associated factors among pregnant, lactating, and nonpregnant women of reproductive age.

METHODS

This cross-sectional and analytical study was conducted online in Turkey, at the end of the fourth wave of the COVID-19 pandemic, between February and May 2022. A total of 658 women (230; 35% pregnant) (187; 28.4% lactating) (241; 36.6% nonpregnant) women of reproductive age participated in the study.

RESULTS

Vaccine acceptance rates were found to be 91.7% in nonpregnant women of reproductive age, 77% in lactating women, and 59% in pregnant women (P < 0.05). The highest rate of vaccine hesitancy was observed in pregnant women (31.3%), and vaccine rejection rate was the highest in lactating women (10.2%). Pregnancy (odds ratio [OR] = 3.98; confidence interval [CI] = 1.13-14.10), and the breastfeeding period (OR = 3.84; CI = 1.15-12.78), increased vaccine hesitancy approximately four times.

CONCLUSIONS

Lack of knowledge about and confidence in the COVID-19 vaccine is still one of the barriers to vaccine acceptance today. Health-care providers (HCPs) should provide effective counseling to pregnant, lactating, and nonpregnant reproductive-aged women based on current information and guidelines.

COVID-19 Vaccination and Its Relation to New-Onset Diabetes: A Narrative Review

The COVID-19 vaccination has been effective in preventing a lot of complications caused by SARS-CoV-2 and its variants. Meanwhile, diabetes mellitus, one of the root causes of many co-morbidities, exhibited itself during the COVID-19 pandemic and after COVID-19 vaccination. Diabetes mellitus introduced itself in a new perspective, leading to a variety of presentations and causing a significant number of emergency admissions. Many of the pre-diabetes patients with no prior history of diabetes developed fulminant type 1 diabetes mellitus (T1DM) after the COVID-19 vaccination. Some cases of conversion of type 2 diabetes mellitus (T2DM) into T1DM were reported. Some prediabetes/diabetes patients presented with the development of diabetic ketoacidosis after COVID-19 vaccination, whereas some previously healthy people with no relation to diabetes also developed acute exacerbations of new-onset T1DM or T2DM along with lethal ketoacidosis. The purpose of writing this review was to explore what kind of people are more prone to develop new-onset diabetes or diabetic complications, including diabetic ketoacidosis, the typical presentation of these patients, possible mechanisms that lead to these complications occurring after the COVID-19 vaccination, how they can be managed, and whether there is a good prognosis after management or not.

Impact of Obesity and Diabetes in Pregnant Women on Their Immunity and Vaccination

Pregnant women with obesity and diabetes are at increased risk of developing infections and other complications during pregnancy. Several mechanisms are involved in the immunological mechanisms that contribute to reduced immunity in these populations. Both obesity and diabetes are associated with chronic low-grade inflammation that can lead to an overactive immune response. Pregnant women with obesity and diabetes often have an increase in pro-inflammatory cytokines and adipokines, such as TNF-α, IL-6, IL-1β, leptin, and resistin, which are involved in the inflammatory response. Insulin resistance can also affect the functioning of immune cells. Furthermore, both conditions alter the composition of the gut microbiome, which produces a variety of biomolecules, including short-chain fatty acids, lipopolysaccharides, and other metabolites. These substances may contribute to immune dysfunction. In addition to increasing the risk of infections, obesity and diabetes can also affect the efficacy of vaccinations in pregnant women. Pregnant women with obesity and diabetes are at increased risk of developing severe illness and complications from COVID-19, but COVID-19 vaccination may help protect them and their fetuses from infection and its associated risks. Since both obesity and diabetes classify a pregnancy as high risk, it is important to elucidate the impact of these diseases on immunity and vaccination during pregnancy. Research examining the efficacy of the COVID-19 vaccine in a high-risk pregnant population should be of particular value to obstetricians whose patients are hesitant to vaccinate during pregnancy. Further research is needed to better understand these mechanisms and to develop effective interventions to improve immune function in these populations.

Impact of COVID-19 Vaccination on Pregnant Women

In light of the COVID-19 pandemic, researchers across the world hastened to develop vaccines that would aid in bolstering herd immunity. Utilizing mRNA coding and viral vector technology, the currently approved vaccines were required to undergo extensive testing to confirm their safety for mass usage in the general population. However, clinical trials failed to test the safety and efficacy of the COVID-19 vaccines in groups with weakened immune systems, especially pregnant women. Lack of information on the effects of vaccinations in pregnancy and the safety of fetuses are among the topmost reasons preventing pregnant women from receiving immunization. Thus, the lack of data examining the effects of COVID-19 vaccinations on pregnant women must be addressed. This review focused on the safety and efficacy of the approved COVID-19 vaccinations in pregnancy and their impact on both maternal and fetal immune responses. For that, we took the approach of combined systematic review/meta-analysis and compiled the available data from the original literature from PubMed, Web of Science, EMBASE and Medline databases. All articles analyzed presented no adverse effects of vaccination in pregnancy, with varying conclusions on the degree of effectiveness. The majority of the findings described robust immune responses in vaccinated pregnant women, successful transplacental antibody transfer, and implications for neonatal immunity. Hence, findings from the cumulative data available can be helpful in achieving COVID-19 herd immunization, including pregnant women.

COVID-19 vaccine acceptance among pregnant women attending antenatal care in public hospitals in eastern Ethiopia: A multi‐center facility‐based cross‐sectional study

Objectives

The Ethiopian government had planned to vaccinate the total population and started to deliver the COVID-19 vaccine but, there is limited evidence about vaccine acceptance among pregnant women. Thus, this study aimed to assess COVID-19 vaccine acceptance and associated factors among pregnant women attending an antenatal care unit clinic in Eastern Ethiopia.

Study design

A facility-based cross-sectional study.

Methods

A study was conducted from June 01 to 30/2021 among systematically selected pregnant women. Data were collected using a pre-tested structured questionnaire, which was adapted from previous studies, through a face-to-face interview. Predictors were assessed using a multivariable logistic regression model and reported using an adjusted odds ratio with 95% CI. Statistical significance was declared at p-value less than 0.05.

Results

In this study, data from 645 pregnant women were used in the analysis. Overall, 62.2% of pregnant women were willing to be vaccinated if the vaccine is approved by the relevant authority. Fear of side effects (62.04%), a lack of information (54.29%), and uncertainty about the vaccine's safety and efficacy (25%) were the most common reasons for refusal to take the COVID-19 vaccine. The odds of unwillingness to accept the COVID-19 vaccine among pregnant women were increased significantly among mothers who were able to read and write [AOR = 2.9, 95% CI: (1.16, 7.23)], attain 9-12 grade level [AOR = 4.2, 95% CI: (2.1, 8.5)], lack information [AOR = 2.2, 95% CI: (1.41, 3.57)], and having a history of chronic diseases [AOR = 2.52, 95% CI: (1.34, 4.7)].

Conclusion

Less than two-thirds of pregnant women were willing to accept the COVID-19 vaccine. Extensive public health information dissemination aimed at women with lower educational backgrounds and a history of chronic disease could be critical.

COVID-19 and Diabetes Mellitus: From Pathophysiology to Clinical Management

An increase in the severity of the coronavirus disease 2019 (COVID-19) was observed in patients infected with the acute severe metabolism syndrome coronavirus type 2 (SARS-CoV-2). Patients who have COVID-19 infection may also be more susceptible to hyperglycemia. When paired with other risk factors, hyperglycemia might alter immune and inflammatory responses, predisposing people to significant COVID-19 and perhaps deadly outcomes. Angiotensin-converting accelerator 2 (ACE2), a component of the renin-angiotensin-aldosterone system (RAAS), is the principal entry receptor for SARS-CoV-2; nevertheless, dipeptidyl enzyme 4 (DPP4) may potentially serve as a binding target. However, preliminary data did not indicate a substantial effect on the susceptibility to SARS-CoV-2 using glucose-lowering DPP4 inhibitors. Because of their pharmacologic characteristics, salt-glucose cotransporter 2 (SGLT2) inhibitors should not be advised for COVID-19 patients because they may have adverse effects. Currently, taking a hypoglycemic drug should be the most efficient way to manage acute glycemia. The majority of market proof is said to categorize two diabetes mellitus (DM) and fails to distinguish between the two primary categories of DM due to its widespread use. For grouping one DM and COVID-19, there is now some constrained proof available. Most of those findings are just preliminary, so further research will undoubtedly be required to determine the best course of action for DM patients.

Psychological and situational factors associated with COVID-19 vaccine intention among postpartum women in Pakistan: a cross-sectional study

OBJECTIVES

Contributing factors to COVID-19 vaccination intention in low-income and middle-income countries have received little attention. This study examined COVID-19-related anxiety and obsessive thoughts and situational factors associated with Pakistani postpartum women's intention to get COVID-19 vaccination.

DESIGN

Cross-sectional study administering a survey by a telephone interview format between 15 July and 10 September 2020.

SETTING

Four centres of Aga Khan Hospital for Women and Children-Garden, Kharadar, Karimabad and Hyderabad-in Sindh Province, Pakistan.

PARTICIPANTS

Women who were enrolled in our longitudinal Pakistani cohort study were approached (n=1395), and 990 women (71%) participated in the survey, of which 941 women who were in their postpartum period were included in the final analysis.

PRIMARY OUTCOME MEASURE AND FACTORS

COVID-19 vaccine intention, sociodemographic and COVID-19-related factors, Coronavirus anxiety, obsession with COVID-19 and work and social adjustment were assessed. Multiple multinomial logistic regression analysis was used to identify factors associated with women's intentions.

RESULTS

Most women would accept a COVID-19 vaccine for themselves (66.7%). Only 24.4% of women were undecided about vaccination against COVID-19, and a small number of women rejected the COVID-19 vaccine (8.8%). Women with primary education were less likely to take a COVID-19 vaccine willingly than those with higher education. COVID-19 vaccine uncertainty and refusal were predicted by having no experience of COVID-19 infection, childbirth during the pandemic, having no symptoms of Coronavirus anxiety and obsession with COVID-19. Predictors for women's intention to vaccinate themselves and their children against COVID-19 were similar.

CONCLUSION

Understanding the factors shaping women's intention to vaccinate themselves or their children would enable evidence-based strategies by healthcare providers to enhance the uptake of the COVID-19 vaccine and achieve herd immunity against Coronavirus.

COVID-19 vaccine uptake and associated factors among pregnant women attending antenatal care in Debre Tabor public health institutions: A cross-sectional study

Background

Vaccination is the best means of reducing the increased risk of severe COVID-19 during pregnancy. Data on COVID-19 vaccine uptake among pregnant women in Ethiopia is scarce. Thus, this study aimed to assess COVID-19 vaccine uptake and associated factors among pregnant women.

Method

An institution-based cross-sectional study was conducted among 634 pregnant women attending antenatal care in Debre Tabor public health institutions from March 14 to 30, 2022. Participants were recruited using a multistage sampling technique and data were collected via face-to-face interviews using a pre-tested structured questionnaire. Stata version 16.0 software was used for data analysis. Multiple logistic regression analysis was used to assess factors associated with COVID-19 vaccine uptake, with a p-value&lt; 0.05 considered statistically significant.

Result

Only 14.4% (95% CI: 11.7%-17.3%) of participants had received at least one dose of COVID-19 vaccines. The main reasons for declining vaccination were fear that the COVID-19 vaccine may have harmful side effects on the fetus or the mother. Being 45 or older (AOR: 1.75, 95%CI: 1.01–2.95), being married (AOR: 1.26, 95%CI: 1.12, 2.96), having good knowledge (AOR:3.52, 95%CI:1.83–3.87), and a positive attitude (AOR:4.81, 95% CI: 1.42–7.33) were positive predictors of COVID-19 vaccine uptake. But attaining a college or university education (AOR: 0.43, 95%CI: 0.12–0.69) was found to be a barrier to vaccine uptake by pregnant women.

Conclusion

COVID-19 vaccination among pregnant women was substantially low. Old age, being married, low education, good knowledge, and a positive attitude were significant predictors of COVID-19 vaccine uptake. To enhance the COVID-19 vaccine uptake, the government should improve the knowledge and attitude of pregnant women toward the COVID-19 vaccine.

Overview of Breastfeeding Under COVID-19 Pandemic

During the global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pregnant and lactating women are at higher risk of infection. The potential of viral intrauterine transmission and vertical transmission by breastfeeding has raised wide concerns. Breastmilk is rich in nutrients that contribute to infant growth and development, and reduce the incidence rate of infant illness and death, as well as inhibit pathogens significantly, and protect infants from infection. Although it is controversial whether mothers infected with COVID-19 should continue to breastfeed, many countries and international organizations have provided recommendations and guidance for breastfeeding. This review presents the risks and benefits of breastfeeding for mothers infected with COVID-19, and the reasons for the absence of SARS-CoV-2 active virus in human milk. In addition, the antiviral mechanisms of nutrients in breastmilk, the levels of SARS-CoV-2 specific antibodies in breastmilk from COVID-19 infected mothers and vaccinated mothers are also summarized and discussed, aiming to provide some support and recommendations for both lactating mothers and infants to better deal with the COVID-19 pandemic.

Molecular and Physiological Aspects of SARS-CoV-2 Infection in Women and Pregnancy

Whilst scientific knowledge about SARS-CoV-2 and COVID-19 is rapidly increasing, much of the effects on pregnant women is still unknown. To accommodate pregnancy, the human endometrium must undergo a physiological transformation called decidualization. These changes encompass the remodeling of endometrial immune cells leading to immunotolerance of the semi-allogenic conceptus as well as defense against pathogens. The angiotensin converting enzyme 2 (ACE2) plays an important regulatory role in the renin-angiotensin-system (RAS) and has been shown to be protective against comorbidities known to worsen COVID-19 outcomes. Furthermore, ACE2 is also crucial for decidualization and thus for early gestation. An astounding gender difference has been found in COVID-19 with male patients presenting with more severe cases and higher mortality rates. This could be attributed to differences in sex chromosomes, hormone levels and behavior patterns. Despite profound changes in the female body during pregnancy, expectant mothers do not face worse outcomes compared with non-pregnant women. Whereas mother-to-child transmission through respiratory droplets during labor or in the postnatal period is known, another question of in utero transmission remains unanswered. Evidence of placental SARS-CoV-2 infection and expression of viral entry receptors at the maternal-fetal interface suggests the possibility of in utero transmission. SARS-CoV-2 can cause further harm through placental damage, maternal systemic inflammation, and hindered access to health care during the pandemic. More research on the effects of COVID-19 during early pregnancy as well as vaccination and treatment options for gravid patients is urgently needed.

COVID-19 vaccine acceptance and associated factors among women attending antenatal and postnatal cares in Central Gondar Zone public hospitals, Northwest Ethiopia

Introduction

The Coronavirus disease 2019 pandemic is a public health problem, which caused a major impact on morbidity and mortality around the world. Even though an effective vaccine is the most awaited resolution for the pandemic, little is known about COVID-19 vaccine acceptance in Ethiopia. This study aimed to assess vaccine acceptance and its associated factors among pregnant and postnatal mothers.

Method

Institution-based cross-sectional study was conducted on 527 pregnant and postnatal mothers from August 15 to September 15, 2021. Data were collected using an interviewer-administered structured questionnaire. A systematic random sampling technique was used to select the study participants. Epi-Data version 4.6 and Stata 16 software were used for data entry and analysis respectively. Participant characteristics and rate of vaccine acceptance were presented using descriptive statistics. Multi-variable logistic regression was performed to identify statistically significant variables. Adjusted odds ratio with 95% confidence interval was used to declare statistical significance based on p < 0.05 in the multivariable logistic regression model.

Result

The overall prevalence of intent to accept COVID-19 vaccine was 62.04% (95% CI: 57.65, 66.25). Of those 40.08% were pregnant mothers and 21.97% of them were postpartum mothers. Urban residence (AOR = 2.03, 95% CI: 1.09–3.77), respondents who were worry about COVID-19 disease (AOR = 3.46, 95% CI: 2.16–5.52), and participants who had favorable attitude towards vaccine (AOR = 8.54, 95% CI: 5.18–14.08) were significantly associated with COVID-19 vaccine acceptance.

Conclusion

Our findings showed that the willingness to accept COVID-19 vaccination was low. Residence, worry about COVID-19 disease, and attitudes towards vaccine were factors significantly associated with COVID-19 vaccine acceptance. Evidence-based and clear information on COVID-19 vaccines should be provided to pregnant and postnatal mothers for both rural and urban residences to improve attitude towards the COVID-19 vaccine and increase vaccination rates.
