If the best study we have (Hong Kong) says post-vax dose 2 myocarditis occurs in 1/2680 12-17 yo boys
& Nordic & French studies say myocarditis post moderna is 3.3-3.7x more common than pos Pfizer, that would give a post dose 2 moderna myo rate of 1/724-812 in 12-17 yo males 🧵

Why is the @US_FDA not concerned about this? Where is the risk-benefit calculation for this group? What evidence do we have healthy children, most of whom have been infected, should even get one dose? I have been asking this for well over a year now, but now... Moderna approved?

Here is the study from Hong Kong 1/2680 myo/pericarditis post dose 2 in boys 12-17

The French study:
Here I used the adjusted odds ratios to compare Moderna to Pfizer = 3.7x difference

Here is the Nordic study. I used excess event rates post moderna vs post pfizer = 3.3x difference

Remember myocarditis post pfizer-moderna combo was calculated to be *28 fold higher* than after covid in 16-24 year old males!

In this case series, 69% still had cardiac abnormalities on MRI 3-8 months later

The @fda stated in May 2021 that the smallpox vaccine may have had a rate of subclinical myocarditis 60x higher than overt myocarditis and we still don't know what the subclinical rate is post mRNA vaccines!

I've been doing so many interviews lately where people are asking me about this that I had to get all of this in one thread. Also because this is simple math the @fda should have done a long time ago.

Data from Ontario actually indicated a 5x greater risk of myo/pericarditis following Moderna in 18-24 year old males. Using the 1/2680 post dose 2 pfizer risk in 12-17yo males would give a 1/536 myo/pericarditis risk post dose 2 moderna in 12-17yo males jamanetwork.com/journals/jaman…
