An infectious disease physician and expert in biochemistry says the risk of myocarditis after a Covid-19 vaccine is very rare but needs to be monitored.
Coroner Robin Kay has released the findings into the death of a 13-year-old on Wednesday.
He couldn't determine whether the boy's second dose of the Pfizer vaccine, 10 days before, was a cause of his fatal myocarditis - or whether another virus was to blame.
University of Otago professor of biochemistry Kurt Krause spoke to Ingrid Hipkiss.
