People who develop rare heart condition myocarditis after receiving a mRNA COVID-19 vaccine are much less likely to die of the condition than those who develop it as a result of a viral infection, according to international research. The team compared 104 people who were hospitalised for myocarditis within a month of their vaccine with 762 people who were diagnosed with myocarditis related to an infection before the pandemic. One person with vaccine-related myocarditis died, representing about 1% of the patients, while 11% of the infection-related myocarditis patients died.
