Scientists Boost Immune Response to COVID-19 Vaccine by 25 Times

Ironically, some vaccines need their own “boosters.” An ingredient called an adjuvant can be added to vaccines to help elicit a more robust immune response, better training the body to fight a pathogen. Scientists report a substance that boosted the immune response to an experimental COVID-19 shot in mice by 25 times, compared to injection with the vaccine alone. Details of the research are described in a new paper published today (August 31, 2022) in the journal ACS Infectious Diseases.
