Deepta Bhattacharya is an associate professor of Immunobiology at the University of Arizona in Tuscon, Arizona.Bhattacharya helped develop the antibody test being used by UArizona.Bhattacharya and Nikolich-Zugich tracked antibody levels over several months in people who tested positive for coronavirus.A research led by Indian-origin Bhattacharya, associate professor at the University of Arizona, has concluded that the antibodies against coronavirus last for around five months in a human body.Using a combination of flavivirus infections, vaccinations and genetic mouse models, Dr. Bhattacharya and his team examined how memory B cells respond to subsequent flavivirus infections.

How well you fare in fighting a new pathogen like SARS-CoV2 depends in large part on how your immune system responds to—and kills—the virus. Increasingly, research suggests that COVID-19 is a disease like many others, at least in some important ways. Immunobiologist Deepta Bhattacharya and New York Times science journalist Katherine J. Wu talk to Ira about the complicated and varied response of the immune system to SARS-CoV2—and why current research suggests we can be optimistic about gaining long-lasting immunity from future COVID-19 vaccines.
Bhattacharya helped develop the antibody test being used by UArizona. So, out of the 250,000 people who get tested for antibodies in Arizona, 4,000 will be selected for a year-long study. The study will look at the number of antibodies a person has over time and will test to see if a person has gotten reinfected with COVID-19. You can go here for more information on the free COVID-19 antibody tests and for more information on the study.
Deepta Bhattacharya, associate professor at the University of Arizona said, "We clearly see high-quality antibodies still being produced five to seven months after SARS-CoV-2 infection". "When a virus first infects cells, the immune system deploys short-lived plasma cells that produce antibodies to immediately fight the virus", Bhattacharya and Professor Janko Nikolich-Zugich from Arizona explained. The researchers added that the antibodies appear in blood tests within 14 days of infection.
