Myocarditis Following the Second Dose of COVID-19 Vaccination in a Japanese Adolescent

Been looking for some medical stuff concerning Myocarditis in Japanese Children. I said in a few previous posts that I would do some research/or talk to a few doctors here in town about this subject. What I'm posting is basically being said with an internist here locally also. I'm still researching stuff in Japanese that I'll have translated into English. Does seem like this should be a concern to ALL LOVING PARENTS.

As per finding: National Library of Medicine

As COVID-19 vaccines continue to be deployed worldwide, countries are now planning to vaccinate their pediatric populations as well. However, several vaccine-related adverse events, including myocarditis, have been reported. Although the incidence of myocarditis after BNT162b2 vaccination is low, it is higher, particularly after receiving the second dose, among young male recipients. A 13-year-old male adolescent presented with chest pain after the second dose of the BNT162b2 vaccination. Electrocardiography, echocardiography, cardiac magnetic resonance imaging, and blood examinations were consistent with myocarditis. He was treated conservatively because his symptoms were relatively mild. In Japan, it is expected that the chances of diagnosing vaccine-related myocarditis will increase as more children are getting vaccinated. Our case report raises concerns to physicians that the COVID-19 vaccination may cause rare cases of myocarditis, which must always be considered as a differential diagnosis.

Conclusions and relevance: In this small case series study, myocarditis was diagnosed in children after COVID-19 vaccination, most commonly in boys after the second dose. In this case series, in short-term follow-up, patients were mildly affected. The long-term risks associated with postvaccination myocarditis remain unknown. Larger studies with longer follow-up are needed to inform recommendations for COVID-19 vaccination in this population.

A total of 747 vaccinated (first dose n = 326; second dose n = 421) and 6300 unvaccinated adolescents were included in analyses of short-term symptoms and 32 vaccinated and 704 unvaccinated adolescents in long-term symptom analyses. In the first 14 days after the first and second vaccine dose the most reported symptoms included headache and muscle or joint symptoms. In both vaccinated and unvaccinated adolescents, the 15-19-year-olds reported significantly higher proportions of all symptoms compared to the 12-14-year-olds. After the second vaccine dose vaccinated 12-14-year-olds reported significantly more headache in adjusted analyses (OR 2.20 (95% CI 1.24; 3.90)). Among the 15-19-year-olds, significantly more vaccinated adolescents reported gastrointestinal symptoms (1.38 (1.06; 1.81)), headache (1.66 (1.24; 2.22)), and tiredness (1.44 (1.08; 1.93)). No differences were found in long-term symptoms. Vaccinated adolescents reported significantly more short-term symptoms including headache, tiredness, and gastrointestinal symptoms after the second vaccine dose than unvaccinated adolescents. Long-term symptom results should be interpreted with caution due to limited sample size

I'm looking at your post as if I'm in my ambulance.....you mentioned zero or little of the fact that it would not even be considered a reaction, side effect for even a 13...or nine year old.

I'd go a dozen different possibles......1st. Not vax related. Why not? Initially, it masks as a dozen different possibilities.

If indicative of unusual possibility...the vax would be the last suspect....not the 1st or only.

Line up 100 vax'd kids with med problems...we wouldn't go there until all other possibilities are exhausted.

Vax bad, probably. Save lives, probably. Have side effects in otherwise healthy adolescents? I'm sure ...but it'd be the last finding to pursue.

Look..I'd have to either save your life transported to treatment...or just guess your kids having a COVID event.

It would be my last triage assessment, not the 1st. Therefore? The Vax is not indicative, but the general histology of the patient, is.This is general, assisted, Emergent-treatment.

If you don't understand the word "Emer-gent"...it initially has zero vax indicators, but could. Just saying....you can't be so matter of fact when ER docs, can't be. Covid vax itself is not an absolute in otherwise healthy kids.

Back in with a point: Casino yesterday, saw woman unconscious being attended.....about 30-40' away.

Even from that distance I could ascertain sex, age aprox, breathing, consciousness, color-palor etc. It would be a last...very last assessment and assumption as to being vax related.

An otherwise healthy 13 yr old. Vax indicators would be last....
