Stress enhances antibody quantity and quality, but impairs immunological memory: Study

Researchers at Tel Aviv University demonstrated for the first time that there is a significant link between behavioral stress and the effectiveness of vaccines. They found that acute stress in mice 9-12 days after vaccination increases antibody response to the vaccine by 70% compared to the unstressed control group. This, however, comes at the price of reduced antibody breadth, which results in diminished protection against the pathogen’s variants.
