(Undated)  --  The World Health Organization is blaming complacency by parents for the increasing cases of measles worldwide.  More than 50 cases have been reported recently in Washington state and Oregon.  The W-H-O reports that the immunization rate in Washington is 90 percent and says that is insufficient to stop an outbreak.  The W-H-O argues parents who may be doubting the science and are not getting their children vaccinated are part of the reason for the increase in cases.  The W-H-O claims that more than 21 million lives have been saved since 2000 because of vaccinations.
