Poll of the Day > Possible link between vaccine and myocarditis

(+) Yeah! (+)

A research article accepted for publication in the journal of the american medical association describes research methodology and findings relating to a possible link between covid vaccine and myocarditis. Compares monthly rates of first time diagnosis of myocarditis pre and post vaccine in a sample of over 2,000,000 vaccine takers. Avereage monthly rate pre vax was 17 vs over 27 post vax. This backs recent cdc reports of vax related myocarditis at an incidence rate of 5 per 1 million, though this research finds a stronger association, which suggests an underreporting of vaccine adverse events.

For every one million Americans immunized with a coronavirus vaccine, about 60 develop temporary heart problems, according to a study published on Wednesday in the journal JAMA Network.

The complications were all short-lived, the researchers found. And these heart problems are far more common among patients who develop Covid-19, outside experts noted.

Analyzing the medical records of just over 2 million people who had received at least one dose of a coronavirus vaccine through May 2021, the new study found 20 cases of myocarditis, or inflammation of the heart muscle, and 37 cases of pericarditis, inflammation of the membrane surrounding the heart.

Patients who were hospitalized were discharged after only a few days, and none died.

The incidence of myocarditis in the study, at 10 cases per million vaccinated, is higher than the Centers for Disease Control and Preventions estimate of 4.8 cases per million, suggesting that there may be more cases than are reported to the federal database for tracking so-called adverse events following vaccinations.

We see that these adverse events are leading to very short and unremarkable hospital stays, said Dr. Jeremy Faust, an emergency medicine physician at Brigham and Womens Hospital in Boston who was not involved in the study. The same cant be said of hospitalizations for Covid-19 in this or any age group so far.

When people are hospitalized for Covid, the consequences are far more severe, added Dr. Faust, who has compared rates of myocarditis following vaccination to those among Covid-19 patients.

The researchers, with the Providence health care system, evaluated medical records from 40 hospitals in Washington, Oregon, Montana and Los Angeles County, Calif.

They found that myocarditis developed a median of 3.5 days after vaccination, mostly after the second dose, and in people with a median age of 36 years. Three-quarters of the 20 cases were in men.

The 19 patients who were admitted to the hospital were discharged after a median of two days. About three weeks after vaccination, 13 patients had recovered from their symptoms and the remaining seven were improving.

Pericarditis affected older patients, at a median age of 59 years, and later, about 20 days after vaccination, the researchers found. Pericarditis, too, was more common in men. Of the 37 cases identified, 13 were admitted to the hospital; the median stay was one day.

A separate study, posted online last week, suggested that the incidence of myocarditis in boys ages 12 to 17 who had Covid-19 was 876 per million; in girls of the same age group with Covid-19, the incidence was 213 cases per million.

The study has not yet been peer reviewed or published in a scientific journal.

Seems to be alarmist and premature. Thanks for sharing, though. Get vaccinated.

There is, astonishingly, no control population to compare unvaccinated incidence to their study (case) population. I really do not understand why they would exclude that. It's literally how you first develop a relationship between treatment and outcome.

just got my second dose today and this is what they told me, and what it says on the paperwork. (says it applies to Pfizer and Moderna).

what if 100% of these myocarditis and similar related problems are literally being caused by people who actually are currently infected with covid when they get their shots?

If only they had a control population to account for that.
