Reports submitted to the U.S. Centers for Disease Control and Prevention (CDC)’s vaccine surveillance system suggest that cases of post-COVID-19 vaccine-linked heart inflammation among young males have risen.
Those reports were presented to the CDC’s Advisory Committee on Immunization Practices on Sept. 1 show that the incident rate for the 12- to 15-year-old group is 150.5 per million—or about 1 in 6,600—and 137.1 per million for the 16- to the 17-year-old group—or about 1 in 7,262.
Following the first booster dose, CDC-presented figures show that it jumps to 188 per million among the 16- to 17-year-old group. But for the 12- to 15-year-old males, 61.3 per million developed heart inflammation after the booster dose, according to the figures.
The agency noted that “myocarditis is a rare event following mRNA COVID-19 booster vaccination” and that it has “verified 131 myocarditis case reports to VAERS in people ages [5 years and older] after 123,362,627 million mRNA COVID-19 booster vaccinations.”
In analyses of the data, “myocarditis [and] pericarditis incidence following first booster dose and dose 2 of the primary series are similar, though case counts are small and confidence intervals around point estimates are wide,” said the CDC.
Another Study
After the figures were presented, the Advisory Committee on Immunization Practices recommended updated boosters, which was, in turn, endorsed by CDC Director Rochelle Walensky, the CDC’s director.“This recommendation followed a comprehensive scientific evaluation and robust scientific discussion. If you are eligible, there is no bad time to get your COVID-19 booster and I strongly encourage you to receive it,” she added on Sept. 1.
Hoeg said she and others published a preprint study last year showing a rate of 94 instances of myocarditis per million in 16- to 17-year-old males—or 1 in 10,600—and 162 per one million in 12- to 15-year-old males—or 1 in 6,200—she wrote on Sept. 1.
“If we hadn’t been villified as ‘anti-vaxxers’ spreading ’mis’ & ’disinformation,' how would the conversation around minimizing the chance of this adverse event have changed & how many cases of myo/pericarditis in young males would have been prevented over the last year?” she asked.
Hoeg also questioned recent statements made by CDC officials in recommending boosters to anyone aged 12 and older.
“Now today the CDC is recommending with no human data on benefits or risks that *everyone* 12 and up get a bivalent booster. ‘There is no bad time to get your COVID-19 booster.’ Really?” she asked. “Why are nuance & individualized recs so difficult for @CDCgov?”
