Study: Flu Shot Not As Effective in
Elders
(London, AP, 9/21/05)
When Dr. Tom Jefferson and his colleagues in the Cochrane
Review Group, an international collaboration of scientists,
analyzed the results of 64 studies spanning 40 years of
research, they concluded that flu vaccines are only about 28 %
effective when given to seniors. Despite this finding, the
World Health Organization (WHO) and the US Centers for Disease
Control and Prevention (CDC) continue to recommend that
seniors get vaccinated to achieve some degree of protection
and to lessen the severity of the illness.
