SARS-CoV-2 post-vaccination adverse reports: A review

Abstract

Acute respiratory infection caused by the SARS-CoV-2 coronavirus was the cause of the pandemic announced in March 2020. To prevent this disease, various vaccines have been developed and introduced into mass use, including on an innovative gene platform. The aim of the review is to analyze foreign literature on post-vaccination complications with the use of foreign vaccines, as well as whole-virion vaccines for the period 2021 — January 2023. The sources used in the publication were obtained from the Medline database, as well as articles in peer-reviewed journals and official reports. Post-vaccination complications are associated with specific damage to organs or systems either directly by the vaccine itself or indirectly as a result of exacerbation of the chronic process. The pathogenesis of post-vaccination complications depends on the composition of the vaccine. All complications were grouped by organs and systems. Vaccines containing SARS-CoV-2 antigens can activate autoimmune reactions due to homology, as well as activation of existing reactions in predisposed patients, which is confirmed by the effectiveness of immunosuppressive therapy. Innovative platforms using gene technologies are so complex and profoundly active that they can be introduced into broad medical practice only after a thorough and comprehensive study of the effects and mechanisms. Scientific achievements should follow the ethical principles of healing, and above all primum non nocere. Experts around the world emphasize the need for continued monitoring of people’s condition in order to protect their health and assess the long-term safety of drugs.
