The benefits of a COVID vaccine far outweigh the small risk of treatable heart inflammation

We are extremely fortunate the global scientific community has been able to develop a handful of highly effective vaccines in such a short time.

As with any vaccine or medicine, the COVID vaccines do carry small risks. The rare blood clotting disorder caused by the AstraZeneca vaccine — thrombosis with thrombocytopenia syndrome, or TTS — has largely dominated the headlines.

But we’re also seeing reports of a potentially increased risk of myocarditis and pericarditis (heart inflammation) following the mRNA COVID-19 vaccines, developed by Pfizer/BioNTech and Moderna.

Here’s why this shouldn’t be cause for concern.

First, what are myocarditis and pericarditis?

There are three main types of heart inflammation: endocarditis, myocarditis, and pericarditis. These involve inflammation of the inner lining of the heart, the heart muscle, and the outer lining of the heart respectively.

Viruses, including the SARS-CoV-2 virus that causes COVID-19, are the most common cause of myocarditis and pericarditis. Essentially, the inflammation the immune system generates to combat infections can inadvertently lead to inflammation of the heart.

In the very rare cases of myocarditis and pericarditis observed after vaccination with a COVID mRNA shot, it’s possible a similar thing might be happening. That is, the vaccine causes the immune system to generate some level of inflammation so it’s prepared to mount a response against SARS-CoV-2, and this inflammation is partially misdirected to the heart.

But the risk is very small, and the conditions are treatable.

What’s the risk?

The exact incidence of myocarditis and pericarditis following vaccination is still being defined, and it remains to be proven that mRNA vaccines are truly the cause of these conditions — although it seems likely.

In Australia, of roughly 3.7 million doses of the Pfizer vaccine administered up to July 11, the Therapeutic Goods Administration (TGA) reports there have been 50 cases of suspected myocarditis or pericarditis. This suggests a risk of one per 74,000 vaccines. The TGA notes most people who developed these conditions have recovered or are recovering.

However, given the relatively small number of vaccinations administered in Australia, it’s important to consider more complete data from countries with higher vaccination rates.

The United States’ Centres for Disease Control and Prevention (CDC) had received 1,226 reports of myocarditis following 296 million doses of mRNA vaccines administered up to June 11. This equates to a risk of roughly one in 240,000 doses. These cases were mostly in young men and predominantly occurred after the second dose.

Independently from vaccines, myocarditis occurs in roughly 23 per 100,000 people worldwide per year (we don’t have reliable figures for pericarditis). This shows us there’s a much lower risk from vaccination than exists in the population generally.

Symptoms to look out for

Normal side effects of COVID-19 vaccines include headache, fever, chills, muscle or joint pain, fatigue and nausea.

In contrast, chest pain, irregular heartbeat, heart palpitations, shortness of breath and light-headedness could indicate myocarditis or pericarditis. Symptoms of these conditions have generally occurred within seven days of vaccination. Anyone who experiences these symptoms should seek medical attention.

In most cases, myocarditis and pericarditis can be successfully treated with anti-inflammatory drugs, such as aspirin and corticosteroids.

In Israel, 95% of cases recently investigated were classified as mild. Similarly, the CDC has reported most patients in the US have recovered quickly.

While this very small risk of heart inflammation following vaccination may be alarming, it’s crucial to understand the risk of heart damage following severe COVID-19 is far greater.

COVID-19 and heart damage

Damage of the heart muscle is a common consequence of coronavirus. Research shows it occurs in up to 28% of patients hospitalised with COVID-19.

Importantly, the risk of death is markedly higher in COVID-19 patients who sustain heart muscle damage. While we need further research to understand precisely how COVID-19 damages the heart, myocarditis and pericarditis are major causes of the heart damage found in COVID-19 patients.

The benefit outweighs the risk

The recent limits applied to the use of the AstraZeneca vaccine in younger age groups suggests the relatively low risk of COVID-19 in Australia justifies being highly selective over vaccine use.

But while Australia has done incredibly well at containing COVID-19, the risk of transmission here remains high given the global COVID-19 situation. We’re seeing this daily as we contend with outbreaks and lockdowns around the country.

Myocarditis and pericarditis are potentially associated with the mRNA vaccines, but these complications are extremely rare, most often mild, and seem to be treatable.

As has been the consistent message from the medical and scientific communities throughout this pandemic, the benefit of COVID-19 vaccines significantly outweighs the risk of rare side effects. This is particularly true for the highly effective mRNA-based vaccines as COVID-19 continues to spread around the world.

Conclusive scientific evidence: homosexuality is treatable


The U.S.-based National Association for Research and Therapy of Homosexuality (NARTH) has just released its long-awaited comprehensive review of over 125 years of scientific research on homosexuality, reports Family Watch International.

This groundbreaking report, “What Research Shows,” dispels the myths that are commonly used to promote the legalization of same-sex marriage and the mainstreaming of homosexuality throughout society and in the public schools by force of law.

NARTH is a professional association of scientists and mental health professionals whose stated mission is to conduct and disseminate scientific research on homosexuality, promote effective treatment, and to protect the right of individuals with unwanted same-sex attraction to receive effective care.

While one might think that such a mission would be viewed as both commendable and relatively non-controversial, the reality is just the opposite. Homosexual activists try to suppress research on same-sex attraction because one of the pillars of homosexual advocacy is the falsehood that homosexuals are “born that way” and cannot change their orientation. Since the NARTH report proves that homosexuality can be changed through therapy in the same way conditions like alcoholism and other addictions can be changed, the whole case for mainstreaming homosexuality into society crumbles. Another myth the NARTH report disproves is that therapy to help people with unwanted same-sex attraction is ineffective and even harmful.

The extensive research and clinical experience reviewed by NARTH makes it clear even to a layman that these claims are false. Homosexual activists spread these misconceptions about homosexuality and even persecute their own who seek treatment because they know that public opinion polls show that people who believe homosexuals are born that way are more likely to support the homosexual agenda. NARTH is one of the very few credible, professional organizations anywhere in the world that is successfully challenging this propaganda.

Specifically, the NARTH report substantiates the following conclusions:

1. There is substantial evidence that sexual orientation may be changed through reorientation therapy.

“Treatment success for clients seeking to change unwanted homosexuality and develop their heterosexual potential has been documented in the professional and research literature since the late 19th century. …125 years of clinical and scientific reports which document those professionally-assisted and other attempts at volitional change from homosexuality toward heterosexuality has been successful for many and that such change continues to be possible for those who are motivated to try.”

2. Efforts to change sexual orientation have not been shown to be consistently harmful or to regularly lead to greater self-hatred, depression, and other self-destructive behaviors.

“We acknowledge that change in sexual orientation may be difficult to attain. As with other difficult challenges and behavioral patterns—such as low-self-esteem, abuse of alcohol, social phobias, eating disorders, or borderline personality disorder, as well as sexual compulsions and addictions—change through therapy does not come easily.”

“We conclude that the documented benefits of reorientation therapy—and the lack of its documented general harmfulness—support its continued availability to clients who exercise their right of therapeutic autonomy and self-determination through ethically informed consent.”

The NARTH report warns that “The limited body of clinical reports that claim that harm is possible—if not probable— if a person simply attempts to change typically were written by gay activist professionals.”

3. There is significantly greater medical, psychological, and relational pathology in the homosexual population than the general population.

“Researchers have shown that medical, psychological and relationship pathology within the homosexual community is more prevalent than within the general population. …In some cases, homosexual men are at greater risk than homosexual women and heterosexual men, while in other cases homosexual women are more at risk than homosexual men and heterosexual women. …Overall, many of these problematic behaviors and psychological dysfunctions are experienced among homosexuals at about three times the prevalence found in the general population—and sometimes much more. …We believe that no other group of comparable size in society experiences such intense and widespread pathology.”
