There are two key points regarding post vaccination heart issues that HART have been raising concerns about since early 2021.
- Myocarditis is attributable to injection not infection
- What has been diagnosed may represent wider harm that is yet to be properly measured
Data from multiple sources now concur on important points. However, there is data from England which appears contradictory.

The purpose of this study is to determine the ECG parameter change and the efficacy of ECG screening for cardiac adverse effect after the second dose of BNT162b2 vaccine in young population. In December 2021, in cooperation with the school vaccination system of Taipei City government, we performed a ECG screening study during the second dose of BNT162b2 vaccines. Serial comparisons of ECGs and questionnaire survey were performed before and after vaccine in four male-predominant senior high schools. Among 7934 eligible students, 4928 (62.1%) were included in the study. The male/female ratio was 4576/352. In total, 763 students (17.1%) had at least one cardiac symptom after the second vaccine dose, mostly chest pain and palpitations. The depolarization and repolarization parameters (QRS duration and QT interval) decreased significantly after the vaccine with increasing heart rate. Abnormal ECGs were obtained in 51 (1.0%) of the students, of which 1 was diagnosed with mild myocarditis and another 4 were judged to have significant arrhythmia. None of the patients needed to be admitted to hospital and all of these symptoms improved spontaneously. Using these five students as a positive outcome, the sensitivity and specificity of this screening method were 100% and 99.1%, respectively. Conclusion: Cardiac symptoms are common after the second dose of BNT162b2 vaccine, but the incidences of significant arrhythmias and myocarditis are only 0.1%. The serial ECG screening method has high sensitivity and specificity for significant cardiac adverse effect but cost effect needs further discussed. What is Known: • The incidence of cardiac adverse effects was reported to be as high as 1.5 per 10 000 persons after the second dose BNT162b2 COVID-19 vaccine in the young male population based on the reporting system. What is New: • Through this mass ECG screening study after the second dose of BNT162b2 vaccine we found: (1) The depolarization and repolarization parameters (QRS duration and QT interval) decreased significantly after the vaccine with increasing heart rate; (2) the incidence of post-vaccine myocarditis and significant arrhythmia are 0.02% and 0.08%; (3) The serial ECG screening method has high sensitivity and specificity for significant cardiac adverse effect.

This is an apples-to-apples, Hungarians-to-Hungarians, same time period comparison! Pretty much the only variable is the extent to which those counties vaccinated their citizens by July 2021, including young people likely to make babies. Again, to remind you: the vaccination rates are a snapshot for July 13, 2021. You can add 9 months to July 2021, which gives you April 2022. Thus, you can see why birth rates in Q1 2022 changed: because of Covid vaccination.
The result? The more vaccination, the greater the declines in the birth rates.
The risk of myocarditis in this large cohort study was highest in young males after the second SARS-CoV-2 vaccine dose, and this risk should be balanced against the benefits of protecting against severe COVID-19 disease.

Speaking this week on The Mail on Sunday’s Medical Minefield podcast, Prof Woolhouse said: ‘I think that lockdown will be viewed by history as a monumental mistake on a global scale, for a number of reasons.
‘The obvious one is the immense harm the lockdown, more than any other measure, did in terms of the economy, mental health and on the wellbeing of society.
…[A study published in Science in February 2021] also found something intriguing: lockdowns could, in a worst-case scenario, actually increase transmission of the virus by up to five per cent.
…As Dr Ali puts it: ‘Some people say lockdowns were beneficial, others that they were really terrible.
‘The reality actually is much closer to the idea that it didn’t make much difference either way.’
For those who made painful sacrifices, that won’t be an easy truth to swallow.
