Initial tests show Geneva nowhere near close to herd immunity
Initial tests show that around 10% of the Geneva population have been exposed to the coronavirus, which would equal nearly 50,000 people.
The study has been measuring the amount of antibodies in the blood stream.
The researchers were surprised to discover it's far less likely those over the age of 50 would have been exposed compared to those aged between 5 and 49.
But the authors say 10% is nowhere near enough for the herd immunity to take effect. The exposure rate needs to be over 50%.
