New study boosts hope for a broad vaccine to combat COVID-19 variants and future coronavirus outbreaks

Science Daily  August 19, 2021
Researchers in Singapore have provided data showing that potent cross-clade pan-sarbecovirus neutralizing antibodies are induced in survivors of severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1) infection who have been immunized with the BNT162b2 messenger RNA (mRNA) vaccine. The antibodies are high-level and broad-spectrum, capable of neutralizing not only known variants of concern but also sarbecoviruses that have been identified in bats and pangolins and have the potential to cause human infection. These findings show the feasibility of a pan-sarbecovirus vaccine strategy…read more. Open Access TECHNICAL ARTICLE
