RESUMEN
BACKGROUND: For pregnant women living with HIV (WLWH), engagement in care is crucial to maternal health and reducing the risk of perinatal transmission. To date, there have been no studies in Canada examining the impact of the COVID-19 pandemic on pregnant WLWH. METHODS: This was a retrospective cohort study assessing the impact of the pandemic on perinatal outcomes for pregnant WLWH using data from the Perinatal HIV Surveillance Program in British Columbia, Canada. We compared maternal characteristics, pregnancy outcomes, and clinical indicators related to engagement with care between a prepandemic (January 2017-March 2020) and pandemic cohort (March 2020-December 2022). We investigated preterm birth rates with explanatory variables using logistic regression analysis. RESULTS: The prepandemic cohort (n = 87) had a significantly (P < 0.05) lower gestational age at the first antenatal encounter (9.0 vs 11.8) and lower rates of preterm births compared with the pandemic cohort (n = 56; 15% vs 37%). Adjusted odds of preterm birth increased with the presence of substance use in pregnancy (aOR = 10.45, 95% confidence interval: 2.19 to 49.94) in WLWH. There were 2 cases of perinatal transmission of HIV in the pandemic cohort, whereas the prepandemic cohort had none. CONCLUSIONS: The pandemic had pronounced effects on pregnant WLWH and their infants in British Columbia including higher rates of preterm birth and higher gestational age at the first antenatal encounter. The nonstatistically significant increase in perinatal transmission rates is of high clinical importance.

Despite success in managing HIV during pregnancy, challenges remain around sustained adherence with antiretroviral therapy (ART), and the suboptimal viral load (VL) suppression during the postpartum period. The objective of this study was to compare VL levels at delivery and during the postpartum period and assess factors associated with lack of viral suppression during the postpartum period in Canada. We combined data from two Canadian prospective cohorts, which included 286 HIV-positive women (352 pregnancies) who delivered between 2012 and 2020. Delivery VL, postpartum VL, and potential factors associated with an undetectable VL (<50 copies/mL), 2-18 weeks after delivery were assessed. To account for the correlation between multiple pregnancies from the same woman, generalized estimating equations were used to assess bivariate associations. Ninety-nine per cent of pregnant women were on ART during pregnancy compared to 93% during the postpartum period. Of those with available VL results (n = 214 pregnancies), 94% of women achieved an undetectable VL at delivery compared to 87% during the postpartum period. The postpartum period is a challenging time for ART use and VL control. Qualitative studies are needed to better understand these challenges and guide us in designing adequate interventions.
RESUMEN
OBJECTIVE: Our objective was to determine the frequency at which CD4 counts drop below 200 cells/mm3 during pregnancy in women living with HIV and to identify factors associated with this. METHODS: Data from 2005 to 2020 from two prospective Canadian cohorts of pregnant women living with HIV were extracted. As per national guidelines, women received antiretroviral therapy and CD4 counts were monitored once per trimester and at delivery. RESULTS: Among 775 included cases, 72 (9.3%) had CD4 counts <200 cells/mm3 at the first pregnancy visit. Of the 703 remaining pregnancies with CD4 counts ≥200 cells/mm3 at the initial visit, 20 (2.8%) were associated with a drop to <200 cells/mm3 . In univariate analysis, factors associated with this drop were coinfection with hepatitis B virus or hepatitis C virus (odds ratio [OR] 4.0, 95% confidence interval [CI] 1.52-10.50), lower first visit CD4 counts (OR 0.165, 95% CI 0.08-0.34), and baseline haemoglobin levels <11 g/dL (OR 2.89, 95% CI 1.04-8.00). In multivariable analysis, only CD4 count at first visit remained independently associated with this drop. A cut-off CD4 count ≤450 cells/mm3 at the first pregnancy visit had a sensitivity of 100% to detect cases of CD4 drop to <200 cells/mm3 . CONCLUSION: A drop of CD4 count to <200 cells/mm3 is uncommon during pregnancy in women living with HIV. Our results suggest that CD4 monitoring only once in pregnancy would be safe in women whose CD4 count is >450 cells/mm3 at the first pregnancy visit.

OBJECTIVE: To compare perioperative and postoperative complications in patients who underwent opportunistic salpingectomy (OS) (removal of the fallopian tubes for ovarian cancer risk reduction during another surgery) at the time of cesarean section (C-section) with those in patients who underwent tubal ligation. DESIGN: A population-based, retrospective cohort study. SETTING: British Columbia, Canada. PATIENT(S): A total of 18,184 patients were included in this study, of whom 8,440 and 9,744 underwent OS and tubal ligation, respectively. INTERVENTION(S): Patients who underwent OS during a C-section were compared with those who underwent tubal ligation during a C-section. MAIN OUTCOME MEASURE(S): We examined the perioperative outcomes, including operating room time, length of hospital stay, surgical complications such as infections, anemia, incision complications, injury to a pelvic organ, or operating room return; postoperative complications, including physician visits for a postoperative infection or visits that resulted in ultrasound or laboratory examinations and hospital readmissions in the 6 weeks after discharge; and likelihood to fill a prescription for antibiotics or analgesics. RESULT(S): The OS group had decreased odds of perioperative complications compared with the tubal ligation group (adjusted odds ratio [aOR], 0.77; 95% confidence interval [CI], 0.61-0.99). Patients who underwent OS did not have increased risks of physician visits for surgical complications, such as infection, or hospital readmissions in the 6 weeks after hospital discharge. In addition, these patients had 18% and 23% increased odds of filling prescriptions for nonsteroidal anti-inflammatory drugs (aOR, 1.18; 95% CI, 1.07-1.28) and opioids (aOR, 1.23%; 95% CI, 1.12-1.35), respectively. CONCLUSION(S): In this population-based, real-world study of OS at C-section, we report decreased perioperative complications and no difference in postoperative complications between patients who underwent OS and those who underwent tubal ligation. Patients who underwent OS had an increased likelihood of filling a prescription for nonsteroidal anti-inflammatory drugs and opioids in the 6 weeks after hospital discharge. This result should be interpreted with caution because we did not have data on over-the-counter medication use and, thus, not all prescription analgesics were captured in our data. Our data suggest that OS after C-section is a safe way to provide effective contraception and ovarian cancer risk reduction.

OBJECTIVE: To evaluate the effectiveness of empiric antibiotic protocols for peripartum bacteremia at a quaternary institution by describing incidence, microbial epidemiology, clinical source of infection, susceptibility patterns, and maternal and neonatal outcomes. METHODS: Retrospective chart review of peripartum patients with positive blood cultures between 2010 and 2018. RESULTS: The incidence of peripartum bacteremia was 0.3%. The most cultured organisms were Escherichia coli (51, 26.7%), Streptococcus spp. (52, 27.2%), and anaerobic spp. (35, 18.3%). Of the E. coli cases, 54.9% (28), 19.6% (10), and 19.6% (10) were resistant to ampicillin, first- and third-generation cephalosporins, respectively. Clinical sources of infection included intra-amniotic infection/endometritis (115, 67.6%), upper and/or lower urinary tract infection (23, 13.5%), and soft tissue infection (8, 4.7%). Appropriate empiric antibiotics were prescribed in 137 (83.0%) cases. There were 7 ICU admissions (4.2%), 18 pregnancy losses (9.9%), 9 neonatal deaths (5.5%), and 6 cases of neonatal bacteremia (3.7%). CONCLUSION: Peripartum bacteremia remains uncommon but associated with maternal morbidity and neonatal morbidity and mortality. Current empiric antimicrobial protocols at our site remain appropriate, but continuous monitoring of antimicrobial resistance patterns is critical given the presence of pathogens resistant to first-line antibiotics.

Early menopause (<45 years) has significant impacts on bone, cardiovascular, and cognitive health. Several studies have suggested earlier menopause for women living with HIV; however, the current literature is limited by reliance on self-report data. We determined age at menopause in women living with HIV and socio-demographically similar HIV-negative women based on both self-report of menopause status (no menses for ≥12 months) and biochemical confirmation (defined as above plus follicle-stimulating hormone level ≥ 25 IU/mL). Multivariable median regression models assessed factors associated with menopause age, controlling for relevant confounders. Overall, 91 women living with HIV and 98 HIV-negative women were categorized as menopausal by self-report, compared to 83 and 92 by biochemical confirmation. Age at menopause did not differ significantly between groups, whether based on self-report (median [IQR]: 49.0 [45.3 to 53.0] vs. 50.0 [46.0 to 53.0] years; p = 0.28) or biochemical confirmation (50.0 [46.0 to 53.0] vs. 51.0 [46.0 to 53.0] years; p = 0.54). In the multivariable model, no HIV-related or psychosocial variables were associated with earlier age at menopause (all p > 0.05). Overall, HIV status per se was not statistically associated with an earlier age at menopause, emphasizing the importance of comparing socio-demographically similar women in reproductive health and HIV research.

Understanding the true burden of tobacco smoking on adverse pregnancy outcomes is critical in generating appropriate interventions to improve outcomes. Self-reporting of human behaviour that is associated with stigma is associated with underreporting in general and may bias the impact of smoking in studies; however, self-reporting is frequently the most practical method of gleaning this information. The objective of this study was to evaluate concordance between self-reported smoking and concentrations of plasma cotinine, a biomarker of smoking, among participants enrolled in two related HIV cohorts. A total of 100 pregnant women (76 living with HIV [LWH] and 24 negative controls) in their third trimester, and 100 men and non-pregnant women (43 LWH and 57 negative controls) were included. Among all participants, 43 pregnant women (49% LWH and 25% negative controls) and 50 men and non-pregnant women (58% LWH and 44% negative controls) were self-reported smokers. The odds of discordance between self-reported smoking and cotinine levels were not significantly different between self-reported smokers and non-smokers, nor between pregnant women and others, but were significantly increased, regardless of self-reported status, among people LWH compared to negative controls. The overall concordance between plasma cotinine and self-reported data among all participants was 94% with a sensitivity and specificity of 90% and 96%, respectively. Taken together, these data demonstrate that participant surveying in a non-judgemental context can lead to accurate and robust self-report smoking data among both persons LWH and not, including in the context of pregnancy.

Birth mode has been implicated as a major factor influencing neonatal gut microbiome development, and it has been assumed that lack of exposure to the maternal vaginal microbiome is responsible for gut dysbiosis among caesarean-delivered infants. Consequently, practices to correct dysbiotic gut microbiomes, such as vaginal seeding, have arisen while the effect of the maternal vaginal microbiome on that of the infant gut remains unknown. We conducted a longitudinal, prospective cohort study of 621 Canadian pregnant women and their newborn infants and collected pre-delivery maternal vaginal swabs and infant stool samples at 10-days and 3-months of life. Using cpn60-based amplicon sequencing, we defined vaginal and stool microbiome profiles and evaluated the effect of maternal vaginal microbiome composition and various clinical variables on the development of the infant stool microbiome. Infant stool microbiomes showed significant differences in composition by delivery mode at 10-days postpartum; however, this effect could not be explained by maternal vaginal microbiome composition and was vastly reduced by 3 months. Vaginal microbiome clusters were distributed across infant stool clusters in proportion to their frequency in the overall maternal population, indicating independence of the two communities. Intrapartum antibiotic administration was identified as a confounder of infant stool microbiome differences and was associated with lower abundances of Escherichia coli, Bacteroides vulgatus, Bifidobacterium longum and Parabacteroides distasonis. Our findings demonstrate that maternal vaginal microbiome composition at delivery does not affect infant stool microbiome composition and development, suggesting that practices to amend infant stool microbiome composition focus factors other than maternal vaginal microbes.

BACKGROUND: Inaccurate penicillin allergy labels lead to inappropriate antibiotic prescriptions and harmful patient consequences. System-wide efforts are needed to remove incorrect penicillin allergy labels, but more health services research is required on how to best deliver these services. METHODS: Data was extracted from five hospitals in Vancouver, British Columbia, Canada from October 2018-May 2022. The primary outcomes of this study were to outline de-labelling protocol designs, identify the roles of various healthcare professionals in de-labelling protocols and identify rates of de-labelling penicillin allergies and associated adverse events at various institutions. Our secondary outcome was to describe de-labelling rates for special populations, including pediatric, obstetric and immunocompromised subpopulations. To achieve these outcomes, participating institutions provided their de-labelling protocol designs and data on program participants. Protocols were then compared to find common themes and differences. Furthermore, adverse events were reviewed and percentages of patients de-labelled at each institution and in total were calculated. RESULTS: Protocols demonstrated a high level of variability, including different methods of participant identification, risk-stratification and roles of providers. All protocols used oral and direct oral challenges, heavily involved pharmacists and had physician oversight. Despite the differences, of the 711 patients enrolled in all programs, 697 (98.0%) were de-labelled. There were 9 adverse events (1.3%) with oral challenges with mainly minor symptoms. CONCLUSIONS: Our data demonstrates that de-labelling programs effectively and safely remove penicillin allergy labels, including pediatric, obstetric and immunocompromised patients. Consistent with current literature, most patients with a penicillin allergy label are not allergic. De-labelling programs could benefit from increasing clinician engagement by increasing accessibility of resources to providers, including guidance for de-labelling of special populations.

Background: To describe baseline antimicrobial stewardship (AMS) metrics and apply AMS interventions in an inpatient obstetrical population. Methods: From October 2018 to October 2019, our tertiary-care obstetrical center reviewed components of our AMS program, which included: (1) antimicrobial consumption data, (2) point prevalence surveys (PPS), and (3) prospective audit and feedback. We reviewed institutional data for antimicrobial consumption from the pharmacy database. Detailed point prevalence surveys were conducted for all antimicrobial prescriptions on two predefined dates each month. Daily audits and feedback assessed the appropriateness of all non-protocolized antimicrobials. Results: Our average antimicrobial length of therapy (LOT) was 12 days per 100 patient-days, where erythromycin (2.33), amoxicillin (2.28), and ampicillin (1.81) were the greatest contributors. Point prevalence surveys revealed that 28.8% of obstetrical inpatients were on antimicrobials, of which 11.2% were inappropriate. Protocolized antimicrobials were 62% less likely (p = 0.027) to be inappropriate. From 565 audited prescriptions, 110 (19.5%) resulted in feedback, where 90% of recommendations were accepted and implemented. The most common reasons for interventions include incorrect dosage, recommending a diagnostic test before continuing antimicrobials, and changing antimicrobials based on specific culture and sensitivity. Conclusions: Antimicrobial use in obstetrics is unique compared to general inpatients. We provide a baseline set of metrics for AMS at our obstetrical center intending to lay the groundwork for AMS programming in our discipline. Antimicrobial protocolization, as well as audit and feedback, are feasible interventions to improve antimicrobial prescribing patterns.
Historique: Décrire les mesures de gouvernance antimicrobienne (GAM) fondamentales et utiliser les interventions de GAM dans une population obstétricale hospitalisée. Méthodologie: D'octobre 2018 à octobre 2019, le centre obstétrical de soins tertiaires a révisé les éléments du programme de GAM, qui incluait : 1) les données sur la consommation d'antimicrobiens, 2) les enquêtes de prévalence ponctuelles (EPP) et 3) la vérification et la rétroaction prospectives. Les chercheurs ont examiné les données institutionnelles relatives à la consommation d'antimicrobiens dans la base de données de la pharmacie. Ils ont effectué des enquêtes de prévalence ponctuelles détaillées sur toutes les prescriptions d'antimicrobiens à deux dates déterminées chaque mois. Les vérifications et les rétroactions quotidiennes ont permis d'évaluer la pertinence de tous les antimicrobiens non protocolisés. Résultats: La durée du traitement antimicrobien moyen était de 12 jours sur 100 jours-patients, et l'érythromycine (2,33), l'amoxicilline (2,28) et l'ampicilline (1,81) étaient les plus utilisées. Les enquêtes de prévalence ponctuelles ont révélé que 28,8 % des patientes obstétricales hospitalisées prenaient des antimicrobiens, dont 11,2 % étaient inappropriés. Les antimicrobiens protocolisés étaient 62 % moins susceptibles d'être inappropriés (p = 0,027). Des 565 prescriptions vérifiées, 110 (19,5 %) ont donné lieu à des rétroactions, et 90 % des recommandations ont été acceptées et mises en Åuvre. Les principales raisons d'intervenir incluaient une posologie inexacte, la recommandation d'un test diagnostique avant de poursuivre l'antimicrobien, ainsi que le changement d'antimicrobien d'après la culture et sensibilité spécifiques. Conclusions: L'utilisation d'antimicrobiens est unique en obstétrique par rapport aux autres patients hospitalisés. Les chercheurs fournissent la série de mesures de GAM de référence utilisée à leur centre obstétrical pour jeter les bases de la programmation de la GAM dans la discipline. La protocolisation des antimicrobiens, de même que la vérification et la rétroaction, est une intervention faisable pour améliorer les profils de prescription d'antimicrobiens.
RESUMEN
Importance: There are limited high-quality, population-level data about the effect of SARS-CoV-2 infection on pregnancy using contemporaneous comparator cohorts. Objectives: To describe maternal and perinatal outcomes associated with SARS-CoV-2 infection in pregnancy and to assess variables associated with severe disease in the pregnant population. Design, Setting, and Participants: CANCOVID-Preg is an observational surveillance program for SARS-CoV-2-affected pregnancies in Canada. This analysis presents exploratory, population-level data from 6 Canadian provinces for the period of March 1, 2020, to October 31, 2021. A total of 6012 pregnant persons with a positive SARS-CoV-2 polymerase chain reaction test result at any time in pregnancy (primarily due to symptomatic presentation) were included and compared with 2 contemporaneous groups including age-matched female individuals with SARS-CoV-2 and unaffected pregnant persons from the pandemic time period. Exposure: SARS-CoV-2 infection during pregnancy. Incident infections in pregnancy were reported to CANCOVID-Preg by participating provinces/territories. Main Outcomes and Measures: Maternal and perinatal outcomes associated with SARS-CoV-2 infection as well as risk factors for severe disease (ie, disease requiring hospitalization, admission to an intensive care unit/critical care unit, and/or oxygen therapy). Results: Among 6012 pregnant individuals with SARS-CoV-2 in Canada (median age, 31 [IQR, 28-35] years), the greatest proportion of cases were diagnosed at 28 to 37 weeks' gestation (35.7%). Non-White individuals were disproportionately represented. Being pregnant was associated with a significantly increased risk of SARS-CoV-2-related hospitalization compared with SARS-CoV-2 cases among all women aged 20 to 49 years in the general population of Canada (7.75% vs 2.93%; relative risk, 2.65 [95% CI, 2.41-2.88]) as well as an increased risk of intensive care unit/critical care unit admission (2.01% vs 0.37%; relative risk, 5.46 [95% CI, 4.50-6.53]). Increasing age, preexisting hypertension, and greater gestational age at diagnosis were significantly associated with worse maternal outcomes. The risk of preterm birth was significantly elevated among SARS-CoV-2-affected pregnancies (11.05% vs 6.76%; relative risk, 1.63 [95% CI, 1.52-1.76]), even in cases of milder disease not requiring hospitalization, compared with unaffected pregnancies during the same time period. Conclusions and Relevance: In this exploratory surveillance study conducted in Canada from March 2020 to October 2021, SARS-CoV-2 infection during pregnancy was significantly associated with increased risk of adverse maternal outcomes and preterm birth.

OBJECTIVES: To investigate treatment patterns of women with isolated fever in labour and evaluate if variables in the sepsis in obstetrics score (SOS) or fetal tachycardia are associated with treatment differences. Our secondary objective was to compare women with isolated fever in labour with women with clinical chorioamnionitis to identify any clinicodemographic differences. METHODS: A retrospective cohort study of 473 patients at BC Women's Hospital who presented with isolated fever in labour between January 2011 and April 2016 compared with a dataset of 1135 women with clinical chorioamnionitis from 2011 to 2016 in the same institution. RESULTS: In our cohort of isolated fever in labour, antibiotics were given 74.2 % of the time, and the majority received cefazolin and metronidazole (80.9%, of those who received antibiotics). Higher maternal temperature and heart rate at time of first fever and fetal tachycardia were associated with more antibiotic use. Slightly higher maternal temperature was associated with use of a saline bolus and blood cultures. The proportion of women with a SOS greater than 5 increased 4.5-fold from time of first fever to time of maximum SOS. There were fewer cesarean deliveries in the isolated fever in labour group compared with the clinical chorioamnionitis group (22.4% vs. 54.0%; P < 0.0001). CONCLUSIONS: Slightly higher maternal temperature was associated with increased treatment, including antibiotic use, saline bolus administration, and blood cultures. As evidenced by the higher proportion of women with an SOS over 5, women with isolated fever in labour may have a propensity to deteriorate clinically.

BACKGROUND: Multiple contraindications to combined hormonal contraceptives (CHC) use exist. The impact of these factors on contraceptive choice, particularly among women living with HIV (WLWH), is not well understood. We measured and compared the prevalence of contraceptive use and contraindications among WLWH and women not living with HIV (controls). METHODS: We examined cross-sectional survey and medical chart data from 83 WLWH and 62 controls, aged 16-49 and sexually active, from 2013-2017. We compared the age-adjusted prevalence and types of contraceptives used in the last month and the proportion of women with CHC contraindications, including drug interactions, medical comorbidities, and smoking at ≥ 35 years old. All WLWH received care at an interdisciplinary, women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older (median [IQR)] 39 [34-43] vs 31 [23-41] years; p = 0.003), had less post-secondary education (37% vs 73%; p < 0.001), and more often had household income < $15,000/year (49% vs 30%; p = 0.006). WLWH trended to higher contraceptive prevalence than controls (80% vs 63%; p = 0.06 adjusted for age). Overall hormonal contraceptive use was similar. However, despite controlling for age, WLWH used CHC less (4% vs 18%; p = 0.006) than controls, and had more frequently undergone tubal ligation (12% vs 2%; p = 0.03). WLWH also experienced more CHC contraindications (54% vs 13%; p = 0.0001), including smoking at ≥ 35 years old (30% vs 6%; p = 0.0003) or a CHC-related drug interaction (all antiretroviral related) (25% vs 0%; p = 0.0001). CONCLUSIONS: WLWH attending our interdisciplinary clinic used hormonal contraception at similar rates as controls, though with different types. Differences may reflect different distributions of CHC contraindications. CHC contraindications present barriers to accessing the full range of contraceptive choices for WLWH. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed, especially when care is provided without the benefit of an interdisciplinary women-centered healthcare team.
BACKGROUND: There are many reasons why individuals cannot use combined hormonal contraceptives (CHC). The impact of these reasons on contraceptive choice for women living with HIV (WLWH) are poorly understood. We measured and compared the prevalence of contraceptive choice and factors that may preclude their use in WLWH. METHODS: We examined survey and medical chart data from 83 WLWH and 62 controls (women not living with HIV), aged 1649 and sexually active, from 2013 to 2017. We compared the prevalence and types of contraceptives used in the last month and the proportion of women with factors that would not allow the use of CHC, including drug interactions, medical conditions, and smoking at ≥ 35 years old. All WLWH received care at a women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older, had less post-secondary education, and more often had household income < $15,000/year. WLWH were more likely to use contraception than controls. Overall hormonal contraceptive use was similar. However, even when accounting for age, WLWH used CHC less than controls, and had more frequently undergone tubal ligation. WLWH also had more reasons that would preclude the use of CHC contraindications including smoking at ≥ 35 years old or a CHC-related drug interaction. CONCLUSIONS: WLWH attending our interdisciplinary clinic used combined hormonal contraception at similar rates as controls, though with different types. Differences may reflect the fact that WLWH more often have factors that do not allow the safe use of CHC. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed.

BACKGROUND: There is significant risk of complications and vulnerability to severe COVID-19 disease in pregnancy, yet hesitancy exists around COVID-19 vaccination during pregnancy and lactation. OBJECTIVE: To summarize the safety, immunogenicity, and effectiveness of COVID-19 vaccines in pregnancy and lactation. SEARCH STRATEGY: A systematic search of MEDLINE, Embase, PubMed, medRxiv, and bioRxiv. SELECTION CRITERIA: Identified original studies published on pregnant and/or lactating individuals who received one or more doses of a COVID-19 vaccine. DATA COLLECTION AND ANALYSIS: A descriptive summary organized by safety, immunogenicity, and effectiveness outcomes of COVID-19 vaccination in pregnancy and lactation. MAIN RESULTS: In total, 23 studies were identified. Humoral response and functional immunity were interrogated and found. Increasing placental transfer ratios in cord blood were associated with increasing time from the first vaccine dose to delivery. Safety data indicated that pregnant and lactating populations experienced vaccine-related reactions at similar rates to the general population. No increased risk of adverse obstetrical or neonatal outcomes were reported. One study demonstrated that pregnant individuals were less likely to experience COVID-19 when vaccinated. CONCLUSION: COVID-19 vaccination in pregnant and lactating individuals is immunogenic, does not cause significant vaccine-related adverse events or obstetrical and neonatal outcomes, and is effective in preventing COVID-19 disease.
