About this study
Official title: Does Covid-19 Vaccination in Patients Undergoing in Vitro Fertilization Affect the Live Birth Rate of Their First Embryo Transfer Cycle: A Prospective Cohort Study
Since emerging in the last months of 2019, over 127 000 000 individuals have suffered severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection, and the documented death toll from coronavirus disease 2019 (COVID-19) had reached 2788639 individuals globally by the end of March 2021 (CDC, 2021).It is hoped that widespread vaccination will further limit viral spread and shorten the length of the pandemic and its impact on morbidity and mortality. There are currently two vaccines against the new coronavirus: inactivated vaccines and mRNA vaccines.Nationwide anti-COVID-19 vaccination began in China in March 2020, using the inactivated vaccine. By the end of September 2021, 2206.054 million doses (including the first and second doses of the vaccine) of the vaccines have been fulfilled.There is still a lack of real-world data to assist clinicians in counseling their IVF patients regarding the possible impact of recent recovery from COVID infection, or vaccination against it, on the potential for success of ART. We aimed to determine the impact of confirmed COVID-19 immunization on IVF outcomes, by comparing live birth rate of the first transfer cycle in patients undergoing IVF with and without COVID- 19 vaccination.

Since emerging in the last months of 2019, over 127 000 000 individuals have suffered severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection, and the documented death toll from coronavirus disease 2019 (COVID-19) had reached 2788639 individuals globally by the end of March 2021 (CDC, 2021).Although a major victory has been achieved in the fight against the epidemic since first case was reported in Wuhan City,, the cumulative death toll is 5,691 by the end of September in China . At the present time, mitigation strategies for controlling the pandemic continue to rely heavily on universal masking, physical distancing, limiting social interactions, and frequent sanitizing measures. It is hoped that widespread vaccination will further limit viral spread and shorten the length of the pandemic and its impact on morbidity and mortality.
There are currently two vaccines against the new coronavirus: inactivated vaccines and mRNA vaccines. Unlike inactivated vaccines, the mRNA vaccine does not use natural pathogens, but artificially synthesizes the gene sequence encoding a specific antigen protein, and then directly injects the mRNA encoding the antigen protein into the human body to induce the immune system to produce antibodies against the new coronavirus. Although some studies have shown that mRNA vaccines do not increase the risk of miscarriage in women, the conclusion is limited due to the lack of non-pregnant women as a control group. At the same time, the impact of inactivated vaccines on female pregnancy is still in a blank state. Nationwide anti-COVID-19 vaccination began in China in March 2020, using the inactivated vaccine vaccine. By the end of September 2021, 2206.054 million doses (including the first and second doses of the vaccine) of the vaccines have been fulfilled. We aimed to determine the impact of confirmed COVID-19 immunization on IVF outcomes, by comparing live birth rate of the first transfer cycle in patients undergoing IVF with and without COVID- 19 vaccination.

Questions about this trial
What is this clinical trial studying?
An observational study of Covid-19 Vaccination, run by Shanghai First Maternity and Infant Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
live birth rate per transfer (time frame: 10 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05063942, which also lists 4 linked publications.
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 1 Oct 2021.
