Although there have been several epidemiological analyses of myocarditis, that simple comparison is never made. Where uninjected people are looked at specifically, there is no evidence of an increase in incidence. HART has previously summarised the data after infection in the injected compared to the uninjected.

An alternative approach is to look at how common myocarditis is over time. Did the incidence increase with the arrival of covid in 2020 or the arrival of injections in 2021?
