More than any other facet of Covid-19, the question of immunity has been a stressful source of good news/bad news whiplash.
Good news: Scientists discovered early on that most people who have been infected with SARS-CoV-2 (the official name for the novel coronavirus) create virus-specific antibodies — special proteins produced by immune cells that help fight off the coronavirus and provide immunity against future infections. This finding helped guide the dozens of vaccines currently under development.
