The roles of early alert and of adjuvant in the control of Hong Kong influenza by vaccines

The roles of early alert and of adjuvant in the control of Hong Kong influenza by vaccines

M R Hilleman. Bull World Health Organ. 1969.

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.
