COVID-19 vaccination is recommended for everyone ages 6 months and older in the United States for the prevention of COVID-19.
Mostly after first or second dose
mRNA vaccines compared to other vaccines
VRM after mRNA vaccines, 1.46 per 100 000 persons
VRM after AZ vaccine, 0.14 per 100 000 persons
P les than 0.001
Denmark, VRM

BNT162b2, 1.4 per 100 000 vaccinated individuals
mRNA-1273, 4.2 per 100 000
(within 28 days of vaccination)
Severe VRM was identified in 95 cases
19.8% of total VRM
(0.22 per 100 000 vaccinated persons)
85 intensive care unit admission
(17.7% of total VRM)
36 cases of fulminant myocarditis
7.5% of total VRM
21 cases required extracorporeal membrane oxygenation
(4.4% of total VRM)
21 more severe adverse events
(4.4% of total VRM)
Eight out of 21 were sudden cardiac dea*** (SCD)
(attributable to VRM proved by an autopsy)
All cases of SCD attributable to VRM were aged under 45 years and received mRNA vaccines
1 heart transplantation
Conclusion
Moreover, SCD should be closely monitored as a potentially fat** complication of COVID-19 vaccination.
Most common presenting symptom
Chest pain or discomfort
Median time from the vaccination to symptom onset, 3 days
(IQR, 1-10 days)
COVID-19 VRM incidence was highest in mRNA-1273 vaccine (Moderna)
Followed by BNT162b2
J and J Ad26 0.20 per 100 000 persons
AZ ChAdOx1 0.14 per 100 000 persons
