Scientists developed a model showing that a fragile, temporary state of immunity emerged during the early epidemic but got destroyed as people changed their social behaviors over time, leading to future waves of infection
Scientists modeling the spread of COVID-19 showed that a temporary state of immunity
arises due to individual differences in social behaviors. This ‘transient collective immunity’—referring to when the susceptible or more social groups collectively have been infected&mdashgets destroyed as people modify their social behaviors over time. For example, someone who isolated in the early days of the epidemic may at some point renew their social networks, meeting with small groups or large crowds.
