It's unclear whether humankind who recover from COVID-19 will be present immune to reinfection from the coronavirus and, if so, how long that immunity will last.
"We don't know very much," says up to two years later, he says. And the more ill the patient was, the more robust and long-lasting the immune response.
Until the recent emergence of SARS-Cov2, the official title of the current coronavirus, and this pandemic, scientists say, there just hasn't been much of a research push to fully understand how and why reinfection in the company of coronaviruses can occur.
"You become colds above and above again, and I don't think we think that we're really thus well protected against any of them, second time around," says Perlman. "You don't care, either, because it's just a cold virus. I mean, you'd like to not become a cold again, yet it's not really a great deal."
This pandemic, he notes, "is a great deal."
He would bet that the virus that causes COVID-19 won't reinfect people. But he wouldn't guess how long their immunity power last.
What's more, some humankind power have stronger safety from reinfection than others.
"Based on other infections where you become a deep lung infection, you are usually protected against the second infection. If you just have a slight COVID-19 infection that involves your top airway, maybe it will behave like a common cold coronavirus and maybe you can be present reinfected again," says Perlman. "We just really don't know. It's even hard to speculate."
Understanding the natural immune response to this virus is important for vaccine development, he notes.
"If the natural infection doesn't do very well in giving you immunity, what is accepted to happen in the company of the vaccine?" says Perlman. "How are we accepted to make sure that that vaccine not only induces a response that works for the next six months, yet two to three years?"
