Insights
COVID-19 vaccination is crucial, but some vaccines like ChAdOx1 and mRNA-1273.2 have reported cardiovascular adverse effects. This review summarizes these complications, their causes, and potential treatments for vaccine safety monitoring.
Area of Science:
- Cardiology
- Immunology
- Vaccinology
Background:
- The COVID-19 pandemic presents a global health crisis.
- Vaccination against SARS-CoV-2 is the primary strategy for pandemic control.
- Reported adverse effects from vaccines (ChAdOx1, Ad26.COV2.S, BNT162b2, mRNA-1273.2) include serious cardiovascular complications.
Purpose of the Study:
- To summarize cardiovascular complications associated with major COVID-19 vaccines.
- To discuss the pathogenesis and potential therapeutics for these adverse events.
- To provide accurate information on vaccine safety amidst public suspicion.
Main Methods:
- Review of reported cardiovascular adverse events following COVID-19 vaccination.
- Analysis of data concerning mRNA vaccines and other major vaccine types.
- Exploration of underlying mechanisms and therapeutic strategies.
Main Results:
- Cardiovascular complications such as myocarditis, immune thrombocytopenia (ITP), and cerebral sinus venous thrombosis have been reported.
- These events impact vaccinee health and influence vaccine administration.
- mRNA vaccines are highlighted as innovative, with ongoing safety monitoring.
Conclusions:
- Monitoring COVID-19 vaccine safety, particularly cardiovascular events, is an urgent and ongoing necessity.
- Understanding pathogenesis and developing therapeutics are key to addressing vaccine-related complications.
- Accurate reporting is vital to combat misinformation and ensure public trust in vaccination programs.
Abstract:
Coronavirus disease 2019 (COVID-19) has become a global public health catastrophe. Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is proven to be the most effective measure to suppress the pandemic. With the widespread application of the four vaccines, namely, ChAdOx1, Ad26.COV2.S, BNT162b2, and mRNA-1273.2, several adverse effects have been reported. The most serious type of complication is cardiovascularly related, including myocarditis, immune thrombocytopenia (ITP), cerebral sinus venous thrombosis, among others. All these adverse events undermine the health of the vaccinees and affect the administration of the vaccines. As the distribution of COVID-19 vaccines is surrounded by suspicion and rumors, it is essential to provide the public with accurate reports from trusted experts and journals. Monitoring the safety of COVID-19 vaccines is an important and ongoing process that is also urgent. Thus, we summarized the cardiovascular complications of the major types of COVID-19 vaccines, including mRNA vaccines, which are now generally considered to be innovative vaccines, and the future for vaccination against COVID-19, in addition to the underlying pathogenesis and potential therapeutics.
