Those antibodies can then provide immunity from future attacks.<\/p>\n<p>John Swartzberg, professor emeritus of public health at the University of California, Berkeley, said it&#8217;s &#8220;likely, but not yet established&#8221; that antibodies produced to fight off the novel coronavirus will prevent a second infection, at least temporarily.<\/p>\n<p>&#8220;There is every reason to think the antibodies we produce against COVID will protect us, based on our experience with other coronaviruses and most, but not all, other infectious diseases,&#8221; Swartzberg told Business Insider.<\/p>\n<p>A March 14 report indicated that monkeys that recovered from exposure to the novel coronavirus <a data-analytics-module=\"body_link\" href=\"https:\/\/www.the-scientist.com\/news-opinion\/monkeys-develop-protective-antibodies-to-sars-cov-2-67281\">did not develop a second infection<\/a> when re-exposed. And we know most humans who survive COVID-19 <a data-analytics-module=\"body_link\" href=\"https:\/\/www.businessinsider.com\/coronavirus-antibody-blood-test-covid-19-2020-3\">develop antibodies<\/a> specific to the disease.<\/p>\n<p>&#8220;That&#8217;s a good sign that we likely have at least temporary immunity after infection,&#8221; Frances Lund, chair of the microbiology department at the University of Alabama at Birmingham, told Business Insider. &#8220;What we don&#8217;t know yet is how long that immunity will last, the quality of that immunity, and whether all individuals will generate a long-lasting high immune response.&#8221;<\/p>\n<p>Another wrinkle is <a data-analytics-module=\"body_link\" href=\"https:\/\/www.businessinsider.com\/study-recovered-coronavirus-patients-antibodies-2020-4\">whether everyone who is exposed to the virus develops antibodies<\/a>, and whether they develop enough to ward off reinfection.

At the six-year mark, though, only two out of 23 patients still had detectable antibodies, suggesting a diminished defense against the virus.<\/p>\n<p>And the novel coronavirus is an RNA virus, like influenza, which means it can mutate. When that happens antibodies built up against one strain aren&#8217;t always effective against another. (That&#8217;s why we need a new flu shot every season.)<\/p>\n<p>But, Lund said, the current coronavirus &#8220;isn&#8217;t changing too much, so we hope this will be less of an issue.&#8221;<\/p>\n<p>Tim Schacker, director of the University of Minnesota&#8217;s HIV medicine program, said that based on similar illnesses, &#8220;I presume that once you have [COVID-19], if you get it again, it will be a milder course.&#8221;<\/p>\n<p>There have been <a data-analytics-module=\"body_link\" href=\"https:\/\/www.businessinsider.com\/south-korea-coronavirus-reactivate-unlikely-dormancy-2020-4\">reports of patients who have seemingly fought off the coronavirus<\/a> only to test positive again weeks or even days later. But those could be attributed <a data-analytics-module=\"body_link\" href=\"https:\/\/www.nytimes.com\/2020\/02\/29\/health\/coronavirus-reinfection.html\">to flaws in testing<\/a>, Florian Krammer, a virologist at Mount Sinai&#8217;s Icahn School of Medicine, told <a data-analytics-module=\"body_link\" href=\"https:\/\/www.nytimes.com\/2020\/02\/29\/health\/coronavirus-reinfection.html\">The New York Times<\/a>.<\/p>\n<p>&#8220;I&#8217;m not saying that reinfection can&#8217;t occur, will never occur, but in that short time it&#8217;s unlikely,&#8221; Krammer said.<\/p>\n<h2>How long could acquired immunity to COVID-19 last?<\/h2>\n<p>It&#8217;s too early to know if exposure will grant lifelong protection from COVID-19, but Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, said he believed someone infected in March would have immunity <a data-analytics-module=\"body_link\" href=\"https:\/\/www.businessinsider.com\/fauci-recovering-from-coronavirus-immunity-through-september-antibodies-2020-4\">at least through September<\/a>, when a second wave of the virus could hit.<\/p>\n<p>&#8220;If this virus acts like every virus we know, once you get infected, you get better, clear the virus, and then you will have immunity that will protect you against reinfection,&#8221; he <a data-analytics-module=\"body_link\" href=\"https:\/\/www.newsweek.com\/fauci-really-confident-people-recover-coronavirus-become-immune-infection-1494612\">told the Daily Show&#8217;s Trevor Noah in late March.<\/a><\/p>\n<p>Scientists are hoping so-called <a data-analytics-module=\"body_link\" href=\"https:\/\/www.businessinsider.com\/coronavirus-antibody-blood-test-covid-19-2020-3\">serological tests<\/a>\u00a0could test for antibodies specific to the coronavirus in people&#8217;s blood, and that those with them \u2014 and the immunity they provide \u2014 could return to work earlier.<\/p>\n<p>As Marc Lipsitch, director of the Center for Communicable Disease Dynamics at the Harvard T.H.
