Experts are divided about the risk posed by a Covid-19 vaccination centre metres away from a quarantine facility’s exercise area in central Auckland, NZ Herald reports. A University of Canterbury professor says the arrangement poses some risk of virus transmission to the public, but a University of Otago epidemiologist disagrees, stating the risk of transmission is close to zero. The concerns came after reports released last week, which found aerosol transmission the most likely cause of two instances of virus transmission between residents in the Grand Mercure and Grand Millennium Auckland quarantine facilities.
