Current evidence from major public health organizations such as the World Health Organization, Centers for Disease Control and Prevention, and European Medicines Agency does not show that COVID-vaccinated people overall have more heart attacks or more disease than unvaccinated people.

However, there are some rare side effects linked to certain COVID vaccines, especially:

Myocarditis/pericarditis (inflammation of the heart muscle or lining)

Mostly seen in:

adolescent and young adult males

usually after the 2nd dose of mRNA vaccines (Pfizer/Moderna)

generally rare and often mild/recoverable 

The Centers for Disease Control and Prevention clearly states that myocarditis after vaccination is rare, and most patients recover well. 

At the same time, large international studies found that:

COVID-19 infection itself increases the risk of heart problems much more strongly, including:

heart attack

stroke

myocarditis

blood clots

long COVID complications 

The European Medicines Agency states there is:

> “no evidence of an increase in deaths related to COVID-19 vaccination in any age group.” 

Important nuance:

Some studies and researchers have questioned whether risks in certain narrow groups (especially young males receiving Moderna during earlier pandemic waves) may have been underestimated. 

But these are debated analyses and do not represent the consensus conclusions of WHO, CDC, EMA, or most cardiology societies.

What the global evidence overall suggests:

Serious vaccine side effects exist but are rare

COVID infection itself caused far higher rates of severe disease and cardiovascular complications

For older adults and high-risk groups, vaccines significantly reduced hospitalization and death

Risk-benefit balance differs by age and sex, especially for young healthy males

So the factual answer is:

No strong evidence shows vaccinated people overall are having more heart attacks or diseases than others because of vaccination alone

Yes, rare heart inflammation cases after vaccination are real and officially acknowledged

COVID infection itself is generally associated with greater cardiovascular risk than vaccination according to major health authorities and most large-scale studies
