  When multiple strains of a pathogen are prevalent in the field, the most effective vaccine strategy involves a combination of multivalent vaccines (targeting multiple strains at once), heterologous prime-boost regimens (mixing different vaccine platforms or strains), and constant environmental surveillance to update vaccine compositions.

  استراتيجية IBV عالميًا: مراقبة السلالات (GI-1 Massachusetts كلاسيكية، GI-16 QX، GI-19 823/Var2، GI-23 DMV/1639) عبر تسلسل S1. لقاحات متعددة (حية H120 + 793B/4/91 + معطل) مع جرعات أولية مبكرة ومنشطات، وفحوصات ELISA/PCR دورية لمطابقة السلالات.
