Óscar Cabrera Adames, a 28-year-old professional basketball player from the Dominican Republic, suffered a heart attack and died while performing a stress test at a health center. A stress test measures the electrical activity of the heart during physical activity. It has not yet been conclusively determined whether undergoing the stress test is what led to the athlete’s heart attack.1
Collapsed, Almost Died After First Pfizer mRNA Shot
Adames had previously collapsed during a basketball game in 2021. He blamed the incident on myocarditis (inflammation of the heart muscle), induced by messenger RNA (mRNA) COVID-19 shots he had received.2 He stated that he had no pre-existing health conditions prior to getting two doses of the Pfizer/BioNTech Comirnaty shot as a condition of employment.
At the time of his collapse after the first Pfizer COVID shot, Adames wrote on his social media page:
But guess what? It was compulsory or I couldn’t work. I am an international professional athlete and I am playing in Spain. I have no health problem, nothing, not hereditary, no asthma, NOTHING! I suddenly collapsed to the ground in the middle of a match and almost died. I’m still recovering and I’ve had 11 different cardiology tests done and guess? They find nothing.3
Pfizer officials denied any connection between the young Adames’ death and its Comirnaty product and claimed reports of myocarditis and pericarditis (inflammation of outer lining of the heart) post vaccination are rare and more likely “unrelated” to vaccination.
A Pfizer spokesperson commented:
Serious adverse events unrelated to vaccination will likely occur at a similar rate in vaccinated individuals as they would in the overall population. With a vast number of people vaccinated to date, the benefit risk profile of our vaccine remains positive.5
Studies Show Much Greater Risk of Myocarditis After Pfizer COVID Shots
A study conducted by U.S. Centers for Disease Control and Prevention (CDC) and several universities and hospitals published in the JAMA Network contradict Pfizer’s denial of a connection between Comirnaty shots and the prevalence of heart inflammation among those, like Adames, who have gotten the shots. The 2022 study showed that the risk of myocarditis after receiving the Comirnaty shot was 133 greater than the normal risk of the myocarditis for the general public. However, this number may actually be much greater due to the way the data was collected.5
The study relied on data from the Vaccine Adverse Events Reporting System (VAERS), which was a vaccine safety provision included in the National Childhood Vaccine Injury Act of (NCVIA) 1986 that centralized vaccine adverse event reporting into one system. VAERS is jointly operated by the U.S. Food and Drug Administration (FDA) and the CDC.
It has long been known that adverse events to vaccination are significantly under-reported. A 2011 Harvard Pilgrim Health Care report found that less than one percent of all adverse reactions to vaccination were reported to VAERS.6 As of July 7, 2023, there had been more than 900,000 adverse events associated with Pfizer/BioNTech mRNA COVID vaccine reported to VAERS.8
Previous studies have also shown the undeniable connection between Comirnaty shots and cases of myocarditis and pericarditis, especially among young men.8 9 10
It was unclear what the long-term repercussion of Comirnaty-induced myocarditis will be. The CDC is investigating the long-term effects of heart inflammation after administration of the Pfizer/BioNTech shot by conducting a survey to gather information.11
