Moderna (NASDAQ:MRNA) COVID-19 vaccine could lead to a higher risk of heart inflammation in certain age groups compared to the rival vaccine from Pfizer (PFE)/BioNTech (BNTX), the U.S. Centers for Disease Control and Prevention (CDC) said Tuesday citing recent data.

However, the agency noted that the incidences of myocarditis and pericarditis, forms of heart inflammation linked to both mRNA-based shots, were not consistent across all of the U.S. vaccine safety monitoring systems.
Vaccine Safety Datalink (VSD) system indicates 97.3 cases per million doses of Moderna (MRNA) vaccine for males aged 18-39 after the second dose compared to 81.7 cases per million of Pfizer (PFE)/BioNTech (BNTX) vaccine doses.
Findings come ahead of a meeting by an independent group of experts at the FDA to decide whether to recommend the use of Moderna (MRNA) COVID-19 shot for those aged 6 to 17 years on Tuesday.
