It’s still not known whether having had COVID-19 gives long-term immunity to the virus, but immediate reinfection is now less of a worry.
What those antibodies mean in terms of long-term protection remains an unanswered question. But Wajnberg's seen at least one hopeful sign.Confirmation in a large study that almost everyone with a symptomatic infection develops antibodies is promising, said Marc Jenkins, director of the Center for Immunology at the University of Minnesota Medical School.
The differences between diseases can be enormous. Some illnesses, such as measles, give lifelong immunity. For others, such as the common cold, immunity wanes after only a few months. “It could be two years, so you could get it now and then you could get it in two years and it’s a pretty severe infection,” he said in a call with reporters Friday.
