How long do antibodies last after COVID-19 infection?
COVID-19Common questionHow long do antibodies last after COVID-19 infection?Dr. Finstad: It appears that antibodies to SARS-CoV-2 last for at least several months.

Another found similar results—people who recovered from COVID-19 had neutralizing antibodies for 6 months.
Can you get reinfected with COVID-19?
COVID-19Common questionCan you get reinfected with COVID-19?COVID-19 reinfections are rare so far, but possible. We may see more cases of reinfection start to happen after some time passes, as our immune response to the virus and vaccination fades, or because new variants of the virus may appear.
Does your immune system get stronger after COVID-19?

What is the duration of natural immunity to COVID-19?
COVID-19Common questionWhat is the duration of natural immunity to COVID-19?Natural immunity can decay within about 90 days. Immunity from COVID-19 vaccines has been shown to last longer. Both Pfizer and Moderna reported strong vaccine protection for at least six months. Studies are ongoing to evaluate the full duration of protective immunity, including the Johnson & Johnson vaccine.
