A vaccinologist is warning against misinformation after a significant Covid data breach

A 56-year-old man will face Wellington District Court today - charged with accessing a computer system for dishonest purposes.

Te Whatu Ora says a staffer downloaded a large amount of vaccine data, which has been posted to an overseas conspiracy site.

Auckland University's Helen Petousis-Harris says the staffer making claims about vaccines is a tech expert - not a health worker.

She says vaccine safety scientists are a better source, for the same reason you wouldn't see a GP for information on computers.
