The health ministry on Monday announced a woman had died due to myocarditis, which is known to be a rare side effect of the Pfizer-BioNTech COVID-19 vaccine. Myocarditis is an inflammation of the heart muscle that can limit the organ’s ability to pump blood and can cause changes in heartbeat rhythms. The health ministry did not provide the woman’s age. Pfizer in New Zealand did not immediately reply to an emailed request for comment.
Moderna Inc’s COVID-19 vaccine contamination woes in Japan have widened with another million doses being suspended after foreign substances were found in more batches and two people died following shots from affected lots.
