Health Editor’s Note: What scientist are finding is that just because someone has had coronavirus and develops antibodies to coronavirus, those antibodies may not be permanent. It seems the more symptomatic the patient, the higher the antibody levels and the longer the antibodies can be found in the patient’s blood.
There is a distinct possibility that to have COVID-19 and recover, does not make it certain that you cannot get COVID-19 again. This is a nasty business as coronavirus has defeated the common antigen/antibody mechanism.
10 Percent of Wuhan Study Patients Lose Coronavirus Antibodies Within Weeks
Chinese scientists have cast doubt over whether we have long-lasting immunity to the coronavirus in two studies released this week, prompting them to question the use of immunity certificates.
The authors of the first study submitted to the pre-print website medRxiv concluded that people are unlikely to have protective antibodies against the coronavirus for long periods of time. As the findings are a pre-print, they have not been through the rigorous peer review process required to publish in scientific journals. Scientists partly release papers this way to prompt debate on a topic.
For the study, the scientists looked for antibodies specific to the coronavirus in the blood samples of 1,470 COVID-19 patients in three hospitals in Wuhan, China—the original epicentre of the pandemic. Previous research cited by the authors suggests that antibodies which make up the first line of defense against the coronavirus are detectable around 7 days after a person is infected, while virus-specific antibodies can take around two weeks.
Dr. Xinghuan Wang of the urology department at Zhongnan Hospital of Wuhan University and colleagues also assessed the blood of 3,832 healthcare providers who didn’t test positive for the coronavirus from one of the three hospitals, as well as 19,555 members of …read more:
