Comparable immune escape capacity for NB.1 with that of JN.1 variant and survey of infection with severe acute respiratory syndrome coronavirus 2 variants among Chinese Felis silvestris catus

Key Points

• NB.1 demonstrates higher immune escape capacity compared to JN.1 among Chinese Felis silvestris catus.
• The study highlights the importance of including the NB.1 antigen in future COVID-19 vaccine candidates.
• Assessment of immune responses in serum illustrates significant differences between the two variants.
• Implications emphasize the need for adjustments in vaccine formulations to combat emerging variants.
