This study shows that elderly individuals vaccinated against SARS-CoV-2 maintain neutralizing antibodies against recent variants, with reduced immune imprinting from ancestral variants after booster doses.

This study assesses cross-neutralisation of sarbecoviruses by COVID-19 vaccines in older adults, finding reduced neutralisation of Omicron variants and some animal sarbecoviruses but enhanced neutralisation of specific bat and pangolin coronaviruses.

The paper identifies a mutation P812S in SARS-CoV-2 associated with immune evasion and upper airway adaptation, but reduced syncytia formation.
