The U.S. Food and Drug Administration (FDA) is set to add a warning to the Covid vaccines made by Pfizer and Moderna after the Centers for Disease Control and Prevention (CDC) said there is a “likely link” between them and cases of heart inflammation, particularly in children and young adults. The MailOnline has the story.
The CDC made the announcement Wednesday during a presentation.
The Covid Vaccine Safety Technical (VaST) Work Group discussed nearly 500 reports of heart inflammation, known as myocarditis, in vaccinated adults under the age of 30.
The group of doctors said the risk of myocarditis or pericarditis following vaccination with the mRNA-based shots in adolescents and young adults is notably higher after the second dose and in males
It comes as the Advisory Committee on Immunisation Practices (ACIP) is set to meet this week to assess the possibility of a link between the heart condition and the mRNA vaccines.
The Moderna and Pfizer vaccines use mRNA technology, while the Johnson & Johnson vaccine uses the more traditional virus-based technology.
According to the presentation, there have been 484 preliminary reports of myocarditis or pericarditis in young people under age 30 as of June 11th.
So far, 323 have been confirmed by CDC and 148 are still under review.
In total, 309 patients were hospitalized, of which 295 were discharged and 79% have since recovered.
Nine patients are still hospitalized with two in intensive care units. There was no data available for five patients.
Males were much more likely to report heart inflammation after receiving a second dose than women.
As of June 11th, there were 9.1 per million reported cases of myocarditis/pericarditis in females ages 12-to-17 compared to 66.7 per million in males of that age group.
What’s more, rates among females ages 18-to-24 and ages 25-to-29 were 5.5 per million and 2.6 per million respectively.
Ang males, rates were 56.3 per million for the 18-to-24 age group and 20.4 per million in the 25-to-29 group.
In Australia, the AstraZeneca Covid vaccine is facing further criticism over its links to a variety of side effects. The vaccine will have been almost completely phased out of the country’s roll-out by October.
