Vaccines And Myocarditis In Young People
Rare cases of inflammation of the heart muscle, or myocarditis, have been found in 1,200 younger people (16-24) after receiving an mRNA vaccine, and this has been used by anti-vaxers to further the hysteria around the vaccine. But, if you talk to a pediatric cardiologist you will learn that we should be much more worried about the disease than the vaccine. There simply is no comparison.
The post-vaccine myocarditis is very mild, has caused no deaths, is easily treated with anti-inflammatory drugs, and quickly goes away without lasting problems. On the other hand, COVID-19 can linger for months, and, as of June 9, has caused ~3000 deaths in young people. Because of this, the American Heart Association and American Academy of Pediatrics continue to strongly recommend vaccination for young people.
Myocarditis in young people is not a new thing, and is usually associated with a viral or bacterial infection. One vaccine against small pox has also been weakly linked to myocarditis. People from puberty through their early 30s are at higher risk for myocarditis, according to the Myocarditis Foundation. Males are affected twice as often as females. Most of these cases are very mild and many times people with myocarditis do not even know they have the problem. The incidence of myocarditis in young people peaks this time of year when the coxsackie virus, which can infect the heart, is more common. This means that an undetermined fraction of post-vaccine myocarditis is likely due to concomitant infection with coxsakie virus and not due to the vaccine.
Bottom line: Post-vaccine myocarditis is much ado about next to nothing. This should not cause one to hesitate getting the vaccine, unless the person has another underlying cardiac problem. The mildness of this rare side effect contrasts with the thousands of young people who have contracted serious COVID-19 and have even succumbed to the infection. While severe morbidity and mortality from COVID-19 is rarer in children and adolescents than in older adults, the number of cases in young people has been steadily rising on a weekly basis according to the CDC. This trend will likely accelerate as the more infectious, and possibly more lethal Delta variant becomes dominant in the US. Since most older adults have been vaccinated, that leaves younger people as available targets for the new virus surge. There is no rational reason for 99.9% of people to not be vaccinated.
