All that said, let me get back to your question! Here&#8217;s a rundown of some of what we know and don&#8217;t know about reinfection:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Reinfection is possible, though relatively rare. It&#8217;s difficult to know just how rare reinfection is because it&#8217;s difficult to measure.

(see <a href=\"https:\/\/covidqanda.org\/?p=122\">Q&amp;A of 10\/14<\/a>)<\/li><li>Risk of reinfection seems to increase with age. (see <a href=\"https:\/\/covidqanda.org\/?p=1234\">Q&amp;A of 3\/18<\/a>)<\/li><li>Neutralizing antibodies produced by previous infection and vaccination are protective for several months, however antibodies after infection vary a good deal from person-to-person.

That\u2019s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19.
