Some scientists have called it "superhuman immunity" or "bulletproof." But immunologist Shane Crotty prefers "hybrid immunity."
"Overall, hybrid immunity to SARS-CoV-2 appears to be impressively potent," Crotty wrote in commentary in Science back in June.
No matter what you call it, this type of immunity offers much needed good news in what seems like an endless array of bad news regarding COVID-19.
Over the past several months, a series of studies has found that some people mount an extraordinarily powerful immune response against SARS-CoV-2. Their bodies produce very high levels of antibodies, but they also make antibodies with great flexibility — likely capable of fighting off the variants of coronavirus circulating in the world but also likely effective against variants that may emerge in the future.
