The consequence is that measles in the elderly has never been observed in a substantial population whose immunity derives primarily from childhood vaccination, because until now no such elderly population has existed. Before vaccination, the question could not be studied either, since nearly everyone was infected by adolescence. We therefore have almost no direct evidence of what measles susceptibility, disease severity, or mortality will look like when vaccine-derived immunity reaches old age. @RobertWMalone
