A gene-expression signature correlates with a person’s likelihood of experiencing adverse events after receiving a seasonal flu vaccine, scientists show. 

The status of a person’s immune system can predict when a seasonal flu vaccination will not provide sufficient protection, according to a study. 

Adding an adjuvant to stimulate both innate and adaptive immunity, researchers boost the effectiveness of an influenza A vaccine in mice.
