Claim Review: Spike Protein from mRNA Vaccines as a Cardiotoxin

The claim that the spike protein generated by the mRNA COVID-19 vaccines is a cardiotoxin, causing an epidemic of heart disease, especially among young patients, has been circulating in various articles and discussions. This claim was made at a meeting of cardiologists in Auckland, New Zealand, and has been reported by Dr. Guy Hatchard in his articles.

To evaluate this claim, it is essential to examine the scientific evidence available. The spike protein produced by mRNA vaccines is designed to mimic the spike protein of the SARS-CoV-2 virus, triggering an immune response. While there have been reports of myocarditis and pericarditis following vaccination, these cases are rare and typically mild. The Centers for Disease Control and Prevention (CDC) and other health authorities have been monitoring these adverse events closely.

A study published in the journal Nature Medicine found that the risk of myocarditis after vaccination is higher in adolescents and young adults, particularly after the second dose of mRNA vaccines. However, the overall incidence remains low, and most cases resolve with appropriate treatment. The study also noted that the benefits of vaccination in preventing severe COVID-19 outcomes outweigh the risks of these rare adverse events.

Furthermore, a systematic review and meta-analysis published in the Lancet Infectious Diseases concluded that the risk of myocarditis is higher after COVID-19 infection than after vaccination. This suggests that the spike protein produced by the virus itself may be more harmful than the vaccine-induced spike protein.

In conclusion, while there is evidence of rare cases of myocarditis and pericarditis following mRNA vaccination, the claim that the spike protein is a cardiotoxin causing an epidemic of heart disease is not supported by robust scientific evidence. The benefits of vaccination in preventing severe COVID-19 outcomes outweigh the risks of these rare adverse events. Therefore, the claim is rated as 2 out of 5.
