US health officials are investigating reports that modern Covid-19 vaccines can be associated with a higher risk of rare heart conditions in younger adults than previously thought, Washington Post reported on Thursday, quoting people who are familiar with reviews .
The report cites the source that says it is too early for regulators to achieve conclusions, and that additional work is needed before the recommendation is made.
Health regulators in June have added a warning to the literature accompanying the MRNA vaccine produced by modern and pfizer to mark the rare risk of heart inflammation seen especially in young men.
However, they said the benefits of shot in preventing Covid-19 continue to exceed the risk.
There may be an incidence of 2.5 times higher than myocarditis on those who get a modern vaccine compared to the Pfizer vaccine, posts quoting the source that says.
The investigation focused on Canadian data shows that the risk of myocarditis may be especially higher for men under the age of 30 years or more, according to the report.
