Anonymous sources citing data collected in Canada have claimed an investigation is being carried out by the US Food and Drugs Administration (FDA) alongside the Centers for Disease Control and Prevention (CDC). According to a report published by The Washington Post, federal officials are looking into claims the Moderna coronavirus vaccine may increase the risk of myocarditis as a side effect. Myocarditis is an inflammation of the heart muscle that is typically caused by infection or an auto-immune disease.
In June this year, the CDC warned of a possible link between heart inflammation and the Moderna and Pfizer vaccines.
The European Medicines Agency (EMA) then warned the side effects may be more common in younger men than other patients.
According to the anonymous sources cited by The Post, the new data from Canada indicates the Moderna vaccine has a higher risk of this rare side effect in younger people, in particular, males under the age of 30.
The data suggest the prevalence of myocarditis is 2.5 times higher in patients who have had the Moderna jab, compared to Pfizer.

However, one of the sources noted it is still too early to issue any official warning.
They said: “We have not come to a conclusion on this. The data are not slam-bang.”
It comes just days after UK regulators confirmed the Moderna vaccine is safe and effective for 12 to 17-year-olds.
What is certain, is the possible risks and side effects associated with the various vaccines do not outweigh the benefits.
The side effects are extremely rare and only affect a handful of people out of tens of millions.
In July, the EMA reported only 19 cases of myocarditis out of 20 million Moderna jabs.

The group also found 145 cases of myocarditis out of 177 million doses of the Pfizer jab.
Covid vaccines have already come under fire this year for their supposed link to blood clots.
The AstraZeneca jab, in particular, was investigated and found to have a “possible link” to very rare cases of “unusual blood clots”.
The EMA reported in April: “The reported combination of blood clots and low blood platelets is very rare, and the overall benefits of the vaccine in preventing COVID-19 outweigh the risks of side effects.”
The various side effects – both real and not – associated with the available Covid vaccines have allowed conspiracy theories and the anti-vax movement to flourish in recent months.

Thousands of social media users have posted unsubstantiated claims about the vaccines being used to microchip people and the coronavirus pandemic being a hoax.
The easily debunked claims persist despite the pandemic already claiming more than 4.4 million deaths worldwide, as of August 20.
In one instance, an article published by The Daily Expose in July claimed to twice as many people have died from Covid vaccines in a six month period than of COVID-19 in 15 months.
The claims were promptly debunked by fact-checkers at Full Fact, who concluded: “This is completely untrue, and is based on misleading conclusions drawn from official data.
“It only counts Covid-19 deaths in England with no underlying conditions, and misuses reports of deaths after Covid-19 vaccines where no causal link can be proven.”
More than 4.9 billion doses of various Covid vaccines have been administered worldwide, with more than 1.9 billion people receiving two doses.
Like all medicines, Covid jabs can cause some known side effects – but these are mild and serious effects are very rare.
The NHS assured: “COVID-19 vaccines have to go through several stages of clinical trials before they can be approved for use.
Clinical trials are where a vaccine or medicine is tested on volunteers to make sure it works and is safe.”
