COLUMBUS, Ohio - A new SARS-CoV-2 vaccine candidate, developed by giving a key protein's gene a ride into the body while encased in a measles vaccine, has been shown to produce a strong immune response and prevent SARS-CoV-2 infection and lung disease in multiple animal studies.
Scientists attribute the vaccine candidate's effectiveness to strategic production of the antigen to stimulate immunity: using a specific snippet of the coronavirus spike protein gene, and inserting it into a sweet spot in the measles vaccine genome to boost activation, or expression, of the gene that makes the protein.
Even with several vaccines already on the market, researchers say this candidate may have advantages worth exploring - especially related to the measles vaccine's established safety, durability and high-efficacy profile.
