SINGAPORE -- Survivors who lived through the SARS crisis in Singapore nearly two decades ago may yield hope for the development of a super vaccine to combat potent COVID-19 variants and even other coronaviruses, new research shows.

Scientists from the city-state's Duke-NUS Medical School and National Centre for Infectious Diseases (NCID) have found "highly potent functional antibodies" in people who had severe acute respiratory syndrome and were vaccinated with Pfizer-BioNTech's shots for COVID-19.
