Patients at the Heart Institute are being treated for an uncommon disease that may be connected to mRNA vaccinations.

At least eight persons have been admitted to the University of Ottawa Heart Institute with an unusual ailment that may be linked to the two mRNA vaccines manufactured by Moderna and Pfizer-BioNTech. Myocarditis is a disorder that causes inflammation of the heart muscle.

The most common symptoms are chest pain, difficulty breathing, and pressure sensations on the chest. The majority of instances are considered mild, and the illness frequently resolves on its own. If the inflammation impairs the heart's ability to pump blood, the patient is given anti-inflammatory medications or steroids.

According to an Ontario Public Health report, post-vaccine problems are extremely rare. In Ottawa, 34 people report adverse effects for every 100,000 doses administered less than 0.03 percent. Caroline Quach, chair of the National Advisory Committee on Immunization, stated that the majority of vaccine-related myocarditis cases involve men under the age of 30 who have gotten their second dose.

Men are more likely than women to get myocarditis. So far, Ontario Public Health isn't observing that vaccinated males are experiencing myocarditis at a higher incidence than the overall population. While researchers are unsure whether mRNA vaccinations cause the unusual disease, Quach believes the timing shows they are related.

Experts continue to emphasize that the benefits of immunization outweigh the risks, and Liu stated that all of the Ottawa patients recovered relatively rapidly. However, he also stated that it is critical to be aware of any potential negative effects. According to a representative for Ottawa Public Health, the department does not provide statistics on bad vaccine reactions, but it does pass data on side effects to the province.
