According to the Nature Medicine Journal, a study was published showing that COVID-19 antibodies only lasted in asymptomatic patients for a few months. The study found that antibodies faded faster in asymptomatic patients than in those who showed symptoms of the Coronavirus. Researchers from Chongqing Medical University in China – where the study was held – compared the immune responses of thirty-seven asymptomatic people diagnosed with COVID-19 to thirty-seven symptomatic patients in the Wanzhou District of China. Forty percent became negative for antibodies early on in their recovery, compared to just thirteen percent of people who developed symptoms. The patients who were asymptomatic also reported lower levels of cytokines, or small proteins released by different cells in the body in response to infection. ~

The study, though small and limited, provides greater insight into how the antibodies for the Coronavirus, SARS-CoV-2, work, and how these antibodies will affect immunity. Most people who have recovered from COVID-19, with or without symptoms, develop antibodies, but the extent and duration of the protection from these antibodies remain unknown. The data suggest that asymptomatic people had a weaker immune response to the virus, similar to the National Institute of Allergy and Infectious Diseases Director Anthony Fauci’s concerns about varying antibody protection. Fauci believes that, due to the small duration to which antibodies of previous coronaviruses remained in patients, COVID-19 antibodies may not be “uniformly robust” (COVID News). ~

Due to the lack of widespread testing for antibodies around the globe, these results are not proven and untested on a large scale. If the study proves to be true, there is a possibility of reinfection after recovering from the Coronavirus. “I think that you’re going to see as the immune response wanes in these respiratory infections, there is a possibility that you could get reinfected,” said Dr. Robert Garry, professor at the Tulane University School of Medicine (ABC). ~
