Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 13 to 49 years
- Women only
- Healthy volunteers accepted
- Child, Adult
Study population: Study population includes women for whom an LMP can be successfully calculated based on a non-missing end of pregnancy (EOP), and who also meet the eligibility criteria to be included in the study analyses.
Who may be able to join
- EOP within study period
- Continuous enrollment in a health plan contributing to the HealthCare Integrated Research Database℠ (HIRD) database for at least 90 days prior to the estimated LMP.
Who cannot join
- Exposure to any non-Moderna COVID-19 vaccines at any time prior to LMP and from LMP through the exposure ascertainment period for the outcome of interest. However, pregnant women exposed to other non-Moderna vaccines in addition to SPIKEVAX will be included in a sensitivity analysis.
- Instances where the outcome of a pregnancy is not documented (e.g., a prenatal care claim is followed by no further documentation of pregnancy, termination, or delivery where the participant remains enrolled in the health plan) may also be observed. The number of these possibly exposed pregnancies will be tabulated and described; however, they will not be included in the descriptive or comparative analyses.

About this study
Official title: An Observational Study to Assess Maternal and Infant Outcomes Following Exposure to SPIKEVAX During Pregnancy
The primary objectives of this study are:
In infants of women exposed to SPIKEVAX during pregnancy, to assess:
- If exposure to SPIKEVAX during pregnancy is associated with an increased birth prevalence of major congenital malformations (MCMs).
- If exposure to SPIKEVAX during pregnancy is associated with an increased birth prevalence of adverse neonatal and infant outcomes, specifically neonatal encephalopathy, small for gestational age, respiratory distress in the newborn, and incidence of hospitalization due to infections including coronavirus disease 2019 (COVID-19).
- In women exposed to SPIKEVAX during pregnancy, to assess whether exposure to SPIKEVAX is associated with an increased prevalence of hypertensive disorders [e.g., pre-eclampsia, eclampsia, and gestational hypertension] gestational diabetes, and post-partum hemorrhage; and
- To assess whether exposure to SPIKEVAX during pregnancy is associated with an increased incidence of stillbirth, preterm birth, and medically attended spontaneous abortion.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| SPIKEVAX Exposed Pregnancy | Cohort includes pregnant women who were vaccinated with SPIKEVAX from last menstrual period (LMP) through the exposure ascertainment period for the outcome of interest. | |
| SPIKEVAX Distantly Exposed Pregnancy | Cohort includes pregnant women who were exposed to SPIKEVAX at least 60 days prior to LMP and not exposed to SPIKEVAX or any other COVID-19 vaccine from LMP through the exposure ascertainment period for the outcome of interest. | |
| Unvaccinated During Pregnancy | Cohort includes pregnant women not exposed to SPIKEVAX or any other COVID-19 vaccine within 60 days prior to LMP through the exposure ascertainment period for the outcome of interest. | |
| COVID-19 Infected During Pregnancy | Cohort includes pregnant women not exposed to SPIKEVAX or any other COVID-19 vaccine within 60 days prior to LMP through the exposure ascertainment period for the outcome of interest. These women also had at least one medically attended COVID-19 episode during the exposure ascertainment period outcome of interest. |

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2024; AzTrials last refreshed its copy on 7 Nov 2026.
