Mayo Clinic: heart inflammation in younger men following COVID-19 vaccinations are rare

JACKSONVILLE, Fla. — As more and more people receive the Covid-19 vaccine doctors are now studying the potential side effects.

Doctors at the Mayo Clinic in Jacksonville at looking at two studies where patients developed myocarditis or inflammation of the heart muscle after getting a Covid-19 vaccine.

“What we found is that it was particularly common in young men between the ages of 18 to 30 after the second vaccine,” Dr. Leslie Cooper the chair of the department of cardiovascular medicine said.

He said the first study published in JAMA Cardiovascular looked at 23 healthy men in the military.

A couple days after receiving a Covid-19 shot they complained of chest pains and were hospitalized.

These men had received Pfizer or Moderna shots which are mRNA vaccines.

However, doctors say more than 2.8 million doses of the vaccine were given out to members of the U.S. military and the majority were perfectly fine.

Dr. Cooper said the chances of developing myocarditis or inflammation of the heart after getting a Covid-19 vaccine is extremely rare and that the overall benefits of getting a vaccine far outweigh the risk.

“The risk of the vaccine is incredibly low even when you look at millions of people who receive the vaccine there are very small risk. Those risk are far lower than the risk of the actual virus and therefore the vaccine is the best choice always,” Dr. Cooper said.

A second study published in the Circulation looked at eight men between the ages of 21 and 56 who were also hospitalized and diagnosed with myocarditis after receiving the vaccine.

But again, Dr. cooper said it’s not something most people need to worry about.

“If you look at a city like Jacksonville and you take, say a million people who live here the chances of getting myocarditis are 220 per year. So about 220 per year in a city out of a million,” he said.

Doctors said it’s important to note that all these young men who had heart inflammation after getting a Covid-19 shot recovered within one to two weeks.
