Purpose

This is a prospective, observational study. During the study, pregnant women will be followed post COVID-19 vaccination. Injection-site (local) and systemic reaction data will be assessed on vaccination day and during the 7 days following the second vaccination using either identical web-based or paper diaries, depending on study participant preference. Maternal serum samples will be collected for antibody titers relevant to COVID-19 at time points that include: prior to vaccination, ~29 days post second vaccination, and at delivery. At Duke University, maternal and infant cord blood will be collected at delivery and analyzed for the same antibody titers. At other clinical sites, these delivery samples will only be collected if feasible. Pregnant women will be followed through 90 days postpartum. with comprehensive obstetric and neonatal outcomes obtained from medical record review.

Inclusion Criteria

  1. Pregnant women 18-45 years of age at the time of consent, inclusive 2. Intention of receiving or within 1 day of receiving the first dose or only dose of COVID-19 vaccine based on Advisory Committee on Immunization Practices (ACIP) and American College of Obstetricians and Gynecologists (ACOG) guidelines in response to the FDA Emergency Use Authorization (EUA) and in conjunction with federal and local vaccination campaign distribution plans 3. Willing to provide informed consent in a written or electronic format 4. Gestational age at time of consent < 34 weeks 0 days based on reconciliation of last menstrual period and ultrasound dating. Estimated due date (EDD) and Gestational Age (GA-EDD) will be based on reconciliation of "sure" first day of the last menstrual period (LMP) and earliest dating ultrasound. If the LMP is uncertain, then the earliest dating ultrasound will be used to determine EDD and GA. If the ultrasound derived-EDD is in agreement with sure-LMP derived EDD, then the LMP-derived EDD is used to determine GA. If the ultrasound derived EDD is not in agreement with the LMP-derived EDD, the ultrasound-derived EDD is used to determine GA. 5. Intention of being available for entire study period and complete all relevant study procedures, including follow-up phone calls and collection of delivery information. 6. English or Spanish literate

Exclusion Criteria

  1. Has immunosuppression as a result of an underlying illness or medications, such as antirejection/transplant regiments or immunomodulatory agents. Stable HIV disease is permitted per the following parameters: a. Confirmed stable HIV disease defined as document viral load <50 copies/mL and CD4 count >200 within 6 months before enrollment, and on stable antiretroviral therapy for at least 6 months 2. Has known hepatitis B (HBV) or hepatitis C (HBC). Stable HBV or HBC are permitted per the following parameters: 1. If known HBV: confirmed inactive chronic HBV infection: HBsAg present for ≥6 months and HBeAg negative, anti-HBe positive; serum HBV DNA <2000 IU/mL; persistently normal ALT or AST levels; in those who had liver biopsy, findings that confirm absence of significant necroinflammation 2. If known HCV: evidence of sustained virological response for ≥12 weeks after treatment or without evidence of HCV RNA viremia (undetectable HCV RNA) 3. Use of oral, parenteral, or high-dose inhaled glucocorticoids 4. Has an active neoplastic disease (excluding non-melanoma skin cancer), including those who used anti-cancer chemotherapy or radiation therapy during the current pregnancy 5. Signs or symptoms of active preterm labor, defined as regular uterine contractions with cervical change (dilation/effacement) 6. Known fetal congenital anomaly, e.g. genetic abnormality or major congenital malformation based on antenatal ultrasound 7. Anyone who is already enrolled or plans to enroll in a randomized clinical trial with any drug, vaccine or medical device. Co-enrollment in behavioral or other observational intervention studies are allowed at any time. 8. Any condition which, in the opinion of the investigators, may pose a health risk to the subject or interfere with the evaluation of the study objectives. 9. Anyone who is a relative of any research study personnel or is an employee supervised by study staff.
