Another study has taken a similar line and suggested herd immunity could develop at around 43 per cent of the population getting infected. 'In our model, the herd immunity threshold declines sharply... and remains below 20 per cent for more variable populations.' The concept of Dr Gomes's reduced herd immunity threshold is based on the groups of the population who are affected. This pushes up the percentage coverage that the health service would have to achieve to get to herd immunity. Those researchers said the key to understanding herd immunity with the coronavirus was looking at social activity.
