In animal tests, scientists used a new approach to flu vaccines. Traditionally, a flu vaccine contains a cocktail of different strains of dead viruses. If the attacking virus is not among those in the cocktail the vaccine does not give immunity. In the new approach, a live virus is used which in addition to an antibody response also gives T cell immunity so that in case of a mutation the T cells can reduce the severity of an infection.
