Are Covid-19 vaccines affecting the heart?
Answer from top 10 papers
COVID-19 vaccines have been associated with cardiovascular side effects, although these events are relatively rare. The literature indicates that while the vaccines are generally safe and effective, there have been reports of myocarditis, particularly with mRNA-based vaccines, and other thromboembolic events (Lin, 2023; Shiravi et al., 2021). These cardiovascular complications can be serious but are considered uncommon when compared to the benefits of vaccination in controlling the pandemic and reducing mortality rates (Shiravi et al., 2021).
Interestingly, while cardiovascular side effects have been observed, the incidence is low, and the specific mechanisms underlying these reactions are still under investigation. The mRNA vaccines, such as those developed by Pfizer/BioNTech and Moderna, have been linked to myocarditis and pericarditis, especially in younger adults following the second dose (Shiravi et al., 2021). Other types of vaccines have been associated with different cardiovascular complications, such as thromboembolic events (Lin, 2023).
In summary, while there is evidence of cardiovascular effects related to COVID-19 vaccines, these are relatively rare and the benefits of vaccination in preventing COVID-19 and its severe outcomes outweigh the risks of these side effects. Continued monitoring and research are essential to further understand and mitigate these risks (Lin, 2023; Shiravi et al., 2021).
