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
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.
Abstract
NB.1 showed increased immune escape capacity in serum compared with JN.1 among Chinese Felis silvestris catus, suggesting that researchers should include the NB.1 antigen in COVID-19 vaccine candidates.
