How long do COVID-19 antibodies last?

There’s still plenty that the scientific community doesn’t know about COVID-19 yet. At the present time no one can say with any certainty how strong the immune response is to future infection, or how long it lasts. The scientific community is understandably cautious about committing to any statements about a virus they haven’t studied for at least two or three years. However, reinfection is rare and what we know about our immune systems would suggest having COVID-19 does give you some protection against catching it again.
