Enhancing the effect of protein-based COVID-19 vaccines

Ironically, some vaccines need their own "boosters." Adding an ingredient called an adjuvant can help vaccines elicit a more robust immune response, better training the body to fight a pathogen. In a new study in ACS Infectious Diseases, researchers 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.
