About this study
Official title: Adverse Events Report of Inactivated COVID-19 Vaccine From 4040 Healthcare Workers
Numerous vaccination studies are conducted to protect against COVID-19 infection, and preclinical and clinical studies are still ongoing worldwide. During this extraordinary period, the necessity to perform COVID-19 vaccine studies and immunization programs together has emerged. Many manufacturing companies have started mass production of vaccines accepting the risk of failure of vaccines during trials. Vaccine Adverse Effects (VAEs) need to be documented quickly. We aimed to determine the VAEs and to compare the frequency of VAEs between groups according to socio-demographic characteristics after the inactivated vaccine (Corona Vac®) was administered to healthcare workers (HCWs) in Turkey.
In this study, an online questionnaire was delivered to volunteer healthcare workers across the whole country. Sociodemographic characteristics, medical history, history of COVID-19 infection, and VAEs occurring after the first and second doses of inactivated vaccine were evaluated.
Read the detailed description
A new coronavirus, severe acute respiratory syncytial coronavirus 2 (SARS-CoV-2) first appeared in China at the end of 2019 and attracted attention with clusters of pneumonia-like cases, which were later defined as coronavirus disease 2019 (COVID-19). Vaccine development is usually achieved over decades and therefore it is unprecedented to have access to such a large number of approved vaccines for COVID-19. In this process, great efforts were made by many organizations to cope with this pandemic that affected the whole world.
COVID-19 vaccines with different features in the form of vector-mediated, messenger RNA (mRNA) or inactivated vaccines are being produced worldwide. CoronaVac® is an inactivated vaccine against severe acute respiratory syncytial coronavirus 2 (SARS-CoV-2) developed by Sinovac Biotech, China which was approved by World Health Organization (WHO) in June 2021.
Vaccine Adverse Effect (VAE) is defined as "any adverse medical event that occurs after vaccination, which is thought to be due to a vaccine.
The primary endpoint of our study was to evaluate the VAEs reported after the first dose and the second doses following the inactivated vaccine (CoronaVac®), which was administered to HCWs in our country as a dose of 3 µg twice, 28 days apart. The secondary endpoint was the comparison of the frequency of VAE development between groups according to socio-demographic characteristics.

Questions about this trial
What is this clinical trial studying?
An observational study of COVID-19 and Vaccine Adverse Reaction, run by Bozyaka Training and Research Hospital at 1 site in Turkey (Türkiye).
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 2 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: finished, as of the sponsor's last update on 2 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Adverse events detection (time frame: 20 minutes). 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 NCT05026879, which also lists 7 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 2 Sep 2021.
