Abstract
The major antigenic changes in influenza A virus that occur at 10-year intervals reduce the effectiveness of existing vaccines and pose a problem for the control of pandemics by vaccination. These difficulties may be obviated in two ways. First, by detecting the emergence of a new variant sufficiently ahead of its general spread for it to be possible to produce a corresponding vaccine in good time; the World Health Organization is widely depended upon for this early warning. Secondly, by the improvement of existing vaccines to increase and broaden their antigenicity; here, their modification by, for instance, adjuvant 65 may contribute significantly.Entities:
