Saegerman et al. perform saliva SARS-CoV-2 testing in a cohort of nursing home workers in Belgium who are either unvaccinated or have received one or two doses of the BNT162b2 mRNA vaccine. The authors show that vaccination protects against shedding of SARS-CoV-2 into saliva and observe greater variability in viral load in the unvaccinated group.
