A 26-year-old New Zealand man’s death from myocarditis has been linked to the Pfizer/BioNTech vaccine by New Zealand officials.

“With the current available information, the board has considered that the myocarditis was probably due to vaccination in this individual,” a COVID-19 Vaccine Independent Safety Monitoring Board said in a statement, according to Reuters.

“The Board noted that Covid-19 infection can itself be a cause of myocarditis, as well as other serious illnesses, and it remains safer to be vaccinated than to be infected with the virus,” the board added, according to Bloomberg.
