Partly_True: Contracting COVID-19 doesn't necessarily create antibodies.

Several studies have found that people with COVID-19 produce antibodies against the virus.The Centers for Disease Control and Prevention (CDC) has stated that, soon after being infected by COVID-19, people's immune systems create antibodies. People who have been infected with COVID-19 trigger a strong immune response in most people. However, several recent studies observed that the number of antibodies in those recovering from the COVID-19 infection appears to decline within a few months of getting recovered from COVID-19, Scientific American reported. However, according to a report published by Nature, many people infected with COVID-19 will probably make antibodies against the virus. Researchers suggest that they have identified long-lived antibody-producing cells in the bone marrow of people who have recovered from COVID-19. In a study by Nature Medicine, blood drawn from 285 people hospitalized with severe COVID-19 found that all had developed SARS-CoV-2 specific antibodies within two to three weeks of their first symptoms. The research in China, led by Ai-Long Huang, Chongqing Medical University, suggested that the immune systems of people who survive COVID-19 recognize SARS-CoV-2 and possibly prevent a second infection, NIH Director's Blog reported. Meanwhile, antibodies present in patients after being infected with COVID-19 do not mean that they are fully protected. In fact, they can recognize the virus and make the proper immune response that could possibly be protective in the future. Moreover, due to a lack of credible scientific evidence, it is unclear if the antibodies will protect recovered patients from reinfection. The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation.
