Research shows that rapid antigen tests are performing as well at detecting the most recent dominant variants as they did with the earliest strains in the COVID-19 pandemic.

Only time and data will tell whether the CDC-recommended reformulated shots can stand their ground against the ever-changing SARS-CoV-2 variants.

Researchers still don’t know how well BA.2.86 will evade immunity or whether it will cause more severe disease than its predecessors.
