Great advances in the science of virology have raised the reasonable hope that all serious virus diseases which affect large portions of mankind will eventually be brought under control by the use of virus vaccines. It has been apparent for some time to virologists that a number of specific problems must be solved before the safest and most effective method of vaccination against each virus disease can be determined. This is readily understood with vaccines in the field trial stage, such as measles virus vaccine. However, to a lesser extent the statement is true even for virus vaccines of proven efficiency, such as the poliomyelitis and influenza virus vaccines.
