COVID-19：抗体的作用，快速下降：伦敦帝国理工学院的调查
电晕抗扰度：
即使您感染了新的日冕病毒并产生抗体，免疫力也有可能迅速下降。
伦敦英国大学帝国学院的一项大规模调查显示。
抗体作用：
抗体的作用可能在几个月后消失。 英国媒体10月27日报道。
伦敦帝国学院调查：
该调查针对英格兰英语地区的360,000多名成年人。
从6月下旬到7月初，检测到的抗体占总数的6％。
但是，在9月，抗体检出率降至4.4％。
每日电讯：
他解释说，即使完成了疫苗接种，免疫力也不会得到充分维持，“每年可能需要接种两次。”

Coronavirus antibody prevalence falling in England, REACT study shows
Tests on more than 365,000 people in England
have shown that the antibody response to the virus that causes COVID-19 wanes over time.
Led by Imperial College London, analysis of finger-prick tests
carried out at home between 20 June and 28 September
found that the number of people testing positive dropped by 26.5% across the study period, from almost 6% to 4.4%.
Our study shows that over time there is a reduction in the proportion of people testing positive for antibodies.
It remains unclear what level of immunity antibodies provide, or for how long this immunity lasts.
Prof Paul Elliott study author, Imperial College London
The downward trend was observed in all areas of the country and age groups, but not in health workers, which could indicate repeated or higher initial exposure to the virus, the authors suggest.
The decline
was largest in people aged 75 and above compared to younger people, and also in people with suspected rather than confirmed infection, indicating that the antibody response varies by age and with the severity of illness.
