It doesn't make sense to compare a study where asymptomatic people were being mass tested for the presence of SARS-CoV-2 RNA with the vaccine trials or the CDC's existing tracking of breakthrough infections, both of which require the presence of symptoms before running any tests. The CDC has even set a lower CT threshold (i.e. higher amount of viral RNA must be present) in order to consider a positive test to be an actual breakthrough infection. https://www.washingtonpost.com/business/can-you-get-covid-twice-what-reinfection-cases-really-mean/2021/04/11/1c738674-9b29-11eb-b2f5-7d2f0182750d_story.html https://www.washingtonpost.com/business/can-you-get-covid-tw...
