研究：新冠病毒抗体可能在数月内消失

血液检测发现，尽管60%的人在和病毒作斗争时身体产生了“强有力的”抗体反应，但只有17%的人在三个月后还有同样强大的抗体。在此期间抗体水平下降到原来的24分之一。在某些情况下，甚至检测不到抗体。

potent [ˈpoʊtnt]: adj. 有效的；强有力的

"People are producing a reasonable antibody response to the virus, but it’s waning over a short period of time and depending on how high your peak is, that determines how long the antibodies are staying around,” said Dr Katie Doores, lead author on the study at King’s College London.

这项研究的首席作者、伦敦国王学院的凯蒂·多萝丝博士说：“人们会对病毒产生足够的抗体反应，但是抗体会在短时间内消退，消退早晚取决于最高点的抗体水平，这决定了抗体能在体内存留多久。”

The immune system has multiple ways to fight the coronavirus but if antibodies are the main line of defence, the findings suggested people could become reinfected in seasonal waves and that vaccines may not protect them for long.

免疫系统有多种方式来抗击新冠病毒，但如果抗体是主要防线，该研究指出人们可能会在季节性疫情中被再次感染，疫苗也可能无法长时间保护他们。

"Infection tends to give you the best-case scenario for an antibody response, so if your infection is giving you antibody levels that wane in two to three months, the vaccine will potentially do the same thing,” said Doores. “People may need boosting and one shot might not be sufficient.”
