The risk of mRNA Covid booster shots, which cause heart inflammation in young adults, continues to worry top scientists considering whether to approve a third dose in people over the age of 12.
Levy, director of the Boston Children’s Hospital Precision Vaccine Program, spoke hours after the FDA’s Advisory Board on Vaccines and Related Bioforms. Unanimously recommended Give a second shot to all recipients of Johnson & Johnsons Single dose Covid vaccine for ages 18 and older.
The panel previously recommended that the FDA approve the booster Modana When Pfizer For all seniors and other high-risk groups. However, some committee members are concerned about allowing people over the age of 12 to receive a third mRNA because of the risk of two rare cardiac inflammatory conditions, myocarditis and pericarditis. I have stated.
“As we enter the younger age group, they have a lower and lower personal risk of severe Covid, while the risk of this inflammatory heart disease from the mRNA vaccine is somewhat higher,” Levy said. I told CNBC.Closing bell.. “It’s a risk-benefit analysis, and that’s why you’re looking at that deliberation.”
Although rare, myocarditis is predominantly found in adolescent men and young adults vaccinated by Pfizer or Modana, according to the US Center for Disease Control and Prevention. According to the CDC, cases usually subside within days of vaccination, usually after a second dose, with medication and rest.
According to the CDC, unlike Pfizer and Moderna mRNA vaccines, J & J’s Covid Shot is not associated with a risk of heart inflammation. Over 15 million Americans have been vaccinated with the primary vaccine by J & J.
The data suggest that both two-dose mRNA options are relatively effective, but J & J submitted a study to the FDA and the second dose provided 72% to 94% protection against symptomatic treatment. Showed that it has improved.
However, Israel has already begun to administer boosters to people over the age of 12 as US health officials are considering deploying boosters to the younger age group. Data submitted to the Commission showed that Israel may have already begun to look at herd immunity.
“The priority is to keep people away from the hospital and stay alive,” Levy said. “But if you can get a level of immunity that reduces the chances of getting infected or spreading to someone else, it’s great because it can direct us to herd immunity.”
