A large-scale study of two million vaccinated people has uncovered evidence that Covid mRNA shots trigger psychiatric adverse events.
The peer-reviewed study was conducted by top Korean scientists and published in the world-renowned Nature Journal.
Led by Eun Mi Chu from the School of Medicine Ewha Womans University in Seoul, South Korea, the team of researchers analyzed the data of two million Korean citizens who had received at least one dose of a Covid mRNA shot.
The study looked into serious adverse events (AEs) of a psychiatric nature linked to COVID-19 vaccination.
The researchers noted that, while evidence associated with an increased risk of psychiatric manifestations does exist after viral infections including COVID-19, such incidence–psychiatric adverse events (AEs) post COVID-19 vaccination as documented in various studies and reports is less clear.
Enter this study, an investigation probing for psychiatric AEs after COVID-19 vaccination from a large population-based cohort in Seoul, South Korea.
The researchers employed statistical tools such as hazard ratios in a population of over 2 million Koreans to determine COVID-19 vaccination is associated with several psychiatric events.
This is an observational study not designed to prove causation.
The team used real-world official government data in the Korean National Health Insurance Service (KNHIS) claims database starting January 1, 2021.
The study investigators recruited 50% of this Seoul-resident population randomly selected.
The vast majority of Korean adults were vaccinated against COVID-19.
Multiple vaccines were used in Korea with the majority of doses being represented by the Pfizer-BioNTech mRNA vaccine.
The study population included a total of 2,027,353 participants from the KNHIS claims database.
