But researchers don't know if the antibodies people may have give complete or just partial protection from coronavirus.

但研究人员尚不清楚人体内可能存在的抗体能否给予人体全面或部分保护，防止感染冠状病毒。

Some experts argue that even partial vaccine protection among a larger number of people is better than complete protection in a smaller group.

一些专家认为，在大量人群中接种部分疫苗比在一小部分人群中接种完整疫苗要好。

Defending the policy shift, Health minister Matt Hancock says partial protection for more people will do more good than full protection for a select few.

卫生部长马克·汉考克为这一政策转变辩护称，对更多人的部分保护要比对少数人的全面保护更加有利。

Yes, but researchers don't know if the antibodies people may have give complete or just partial protection from coronavirus, and they don't know how long those antibodies will stick around in someone's system.

有，但是研究人员不清楚可能存在于人体的抗体能否给予人体全面保护，也不知道这些抗体能够在人体免疫系统存在多长时间。
