The present invention relates to an attenuated strain of avian infectious bronchitis virus and a vaccine composition containing same. With weak pathogenicity and high immunogenicity, the attenuated strain of the present invention can induce defensive capabilities against the avian infectious bronchitis virus and thus can be advantageously used as an attenuated live vaccine. La présente invention concerne une souche atténuée du virus de la bronchite infectieuse aviaire et une composition vaccinale la contenant. Avec une faible pathogénicité et une immunogénicité élevée, la souche atténuée de la présente invention peut induire des capacités défensives contre le virus de la bronchite infectieuse aviaire et peut ainsi être avantageusement utilisée en tant que vaccin vivant atténué. 본 발명은 닭 전염성 기관지염 바이러스 약독화주 및 이를 포함하는 백신조성물에 관한 것이다. 본 발명의 약독화주는 병원성이 약하고 면역원성이 우수하여 닭 전염성 기관지염 바이러스에 대한 방어능을 유발할 수 있어 약독화 생백신으로서 유용하게 사용할 수 있다.
