ABSTRACT
As SARS-CoV-2 variants accumulate mutations, there is a risk of ineffective neutralizing antibodies against new variants and potential re-infection. Halfmann et al. report that, in the hamster model, previous infection with an early prototypical SARS-CoV-2 isolate prevents re-infection of the Delta variant and its transmission to naïve hamsters.
