Genomic Evidence of SARS-CoV-2 Reinfection Involving E484K Spike Mutation, Brazil

Uncertainty remains about how long the protective immune responses against severe acute respiratory syndrome coronavirus 2 persists, and suspected reinfection in recovered patients has been reported. We describe a case of reinfection from distinct virus lineages in Brazil harboring the E484K mutation, a variant associated with escape from neutralizing antibodies.

Automated summary

The case of reinfection from distinct virus lineages in Brazil with the E484K mutation raises concerns about the duration of protective immune responses against SARS-CoV-2, especially with the variant associated with escape from neutralizing antibodies. This highlights potential challenges for virus control measures.
