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. The immune system’s job is to protect you from invasions, both right after you’re infected as well as when you encounter similar viruses in the future.
As the pandemic marches on, we still don’t know exactly how our immune systems tackle this virus. The people who get the sickest seem to have an exaggerated, but ineffective immune response that turns on their own bodies. Others have lasting symptoms, sometimes for months. Immune responses even seem to vary based on your sex.
Increasingly, research suggests that COVID-19 is a disease like many others, at least in some important ways. Your body remembers the virus, and may therefore fight it more effectively the next time you encounter it—which has big implications for eventually developing an effective vaccine.
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.
