Less than a year after the global emergence of coronavirus SARS-CoV-2, novel vaccine platform based on mRNA technology was introduced to market. Globally, around 13.38 billion COVID-19 doses diverse platforms have been administered. To date, 72.3% total population has injected at least once with vaccine. As immunity provided by these vaccines rapidly wanes, their ability prevent hospitalization and severe disease in individuals comorbidities recently questioned, increasing evidence shown that, as many other vaccines, they do not produce sterilizing immunity, allowing people suffer frequent re-infections. Additionally, recent investigations found abnormally high levels IgG4 who were administered two or more injections vaccines. HIV, Malaria, Pertussis also reported induce higher-than-normal synthesis. Overall, there are three critical factors determining class switch antibodies: excessive antigen concentration, repeated vaccination, type used.

Soon after, it was declared a pandemic World Health Organization. The health crisis imposed new virus and its rapid spread worldwide prompted fast development of vaccines. For time human history, two vaccines based on recombinant genetic material technology were approved for use. These mRNA applied massive immunization programs around world, followed other more traditional approaches. Even though all tested clinical trials prior to their general administration, serious adverse events, usually very low incidence, mostly identified after application millions doses. Establishing direct correlation (the cause-effect paradigm) between vaccination appearance effects has proven challenging.

This review examines the immunological and autoimmune adverse events associated with COVID-19 vaccines, highlighting their frequencies, reported cases, associations specific vaccine classes. The concept of vaccine-induced immune thrombotic thrombocytopenia is crucial in addressing skepticism. Understanding this helps healthcare professionals identify manage potential after vaccination. Despite rarity, cause concern anxiety among public. To maintain public trust vaccination programs, health agencies must actively monitor address these events, promptly disclose suspicious incidents, take measures to mitigate dangers, inform transparency accurate information. Continuing research surveillance are essential for understanding underlying mechanisms developing strategies minimize occurrence.
