Immunologist worried about Covid case spike for summer

A leading immunologist is concerned that a lack of reliable data means we could be heading into the Christmas period with far more Covid infections than we're aware of. University of Auckland senior lecturer and immunologist Anna Brooks wants surveillance testing to be reintroduced so we can get a better picture of the state of the pandemic in this country. Another tool we now have to help us do this is antibody tests, which can confirm whether you've had the virus and which are now publicly available. Dr Brooks spoke with Anna Thomas.
