These findings suggest that among persons with previous SARS-CoV-2 infection, full vaccination provides additional protection against reinfection. To reduce their risk of infection, all eligible persons should be offered vaccination, even if they have been previously infected with SARS-CoV-2.&#8221;\u00a0 Please keep talking to your friend about the benefits of vaccination&#8211; for him and all of us!\u00a0\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Question:\u00a0My friend insists he doesn&#8217;t need the vaccine because he&#8217;s already been infected.\u00a0 Is previous infection\u00a0as protective as vaccination?
