"Our Social Activity Measure has recorded increases in multiple forms of social activity: there are more people going to work, more visits to homes, individuals meeting with more people from outside their household, and higher numbers of close contacts. This is to be expected as restrictions lift. However, the data also reveal that these increases are much stronger among people who have been vaccinated. Most people who are not yet vaccinated are continuing to be cautious. Our data are consistent with the majority of people waiting until they are vaccinated before increasing their activity again."
