If I already recovered from Covid-19 infection, can I be sure I won’t get it again or pass it to others?

Is it true that some people already have antibodies to SARS-CoV-2 from previous exposure to seasonal coronaviruses?

Biology/Immunity

A: Maybe; there *is* evidence of antibodies to seasonal coronaviruses reacting to some parts of the SARS-CoV-2 virus. BUT so far there is no solid evidence that these antibodies protect from COVID-19 infection or disease. What does it mean to have “cross-reactive” antibodies?
