Scientists who conducted new research placed less emphasis on basic antibodies that have been used previously to detect traces of immunity, the Express reports. The reliance on antibodies is said to influenced previous attempts to measure immunity in the public.

Marcus Buggert, assistant professor at Karolinska Institutet, believes that initial immunity figures are a miscalculation.
