Evidence from previous work with seasonal coronaviruses and studies of SARS-CoV-2 vaccines in macaques suggests that previous infection or vaccination might protect from severe disease but an individual might nevertheless carry the virus at similar levels, and for a similar duration, to those previously uninfected, with an unchanged potential for transmission. ./cache/cord-354881-7o20cn1x.txt ./txt/cord-354881-7o20cn1x.txt
