Studies conducted in April and May 2020 showed that in countries like the United States, Switzerland, and Italy, between 55 and 70% of adults in all age groups were willing to download a contact tracing app (5).

Yet these figures do not match the current DCT apps uptake. Even in countries with robust privacy safeguards in place, downloads of DCT apps have been below expectations. At the time of writing, the Australian DCT app has been downloaded by 6.5 million (26% of the population), the Italian one by 8 million (13.4%), and the newly released French one by 1.5 million (2.3%). Ireland has about 1.3 million active app users (24%), Switzerland 1.8 million (21.5%), and Germany 16 million (19.3%).

In early May, most Americans (55 percent) said they would get vaccinated for COVID-19 if and when a vaccine becomes available. 

Now, four months later, less than a third of Americans (32 percent) say they plan to get vaccinated, according to the latest Yahoo News/YouGov poll — a stunning 23-point decline that reflects rising concern about the politicization of the vaccine process and underscores how challenging it will be to stop the pandemic through vaccination alone.
