日語 Japanese：心筋炎(しんきんえん)
類義 Synonym：Myopericarditis
意味 Meaning：Myocarditis is a disease caused by a virus that infects the myocardium (the muscle of the heart). Specific symptoms include inflammation of the myocardium, contractile dysfunction of the myocardium, and cardiac arrhythmia. In short, myocarditis means that the heart does not work properly due to the virus.
The Pfizer vaccine (BNT162b2) and the Moderna vaccine (mRNA-1273), mRNA vaccines that were introduced to the market in 2021, have different side effects depending on the age of the patient. They have been shown to increase the probability of myocarditis in humans under 40 years of age. In particular, males in their teens and twenties are at increased risk.

20220121 JP Gov. approved vaccine for age 5--11：
The Japanese government approved the Pfizer vaccine for children aged 5 to 11.
20211227 Allegations of unvaccinated government health staff：
Allegations of unvaccinated government health staff, MHLW (Ministry of Health, Labour and Welfare of Japan), spread on Twitter. It is inconceivable that the government does not keep the vaccine data of its own employees. The MHLW has its own reasons for not clearing its suspicions.
データ分析 Data analysis：
20211220 Hyaluronic acid search volume in upward trend：
The search volume for hyaluronic acid (HA) has risen and is about 10 times higher than in 2004. The search volume chart formed a mountain range in the first half of 2021.
20211218 Myocarditis search volume 10 times higher than average years：
The search volume for myocarditis was constant from 2004 to 2020. The volume of technical terms tends to be more stable than that of general terms. Contrary to this search engine rule, the volume of "myocarditis" soared up to 10 times in 2021, remaining high.
20211202 20 Million Doses in Ontario Determined High-Risk Factors：
Data from nearly 20 million doses in Ontario, Canada, determined factors that increase the risk of myocarditis as a side effect after receiving the mRNA vaccine. The factors associated with higher risk are:
Short intervals between boosters > Long intervals between boosters
Younger age group > Older age group
Male > Female
20210710 Autopsy on man killed by Pfizer vaccine in South Korea：
A 22-year-old man in South Korea died after receiving the Pfizer vaccine (BNT162b2). The man was a newly recruited military officer. Prior to his enlistment, the data from the "7-month pre-medical checkup" and the "17-month pre-medical checkup" had been well preserved, respectively. The South Korean Ministry of National Defense (國防部 국방부) concluded from the autopsy results that the disease was caused by the Pfizer Biotech vaccine (BNT162b2) and submitted a paper. In the paper, they pointed out that "young males + the second dose of vaccine" were at risk. Also, no blood clots were found.
