I'm curious as to how many of those were elementary school-aged children (lets say under 10).  From the same article it looks like about 50 children and 50 adults (all w/o other complications).<p>I wonder what the results would be if the standard was to give a vaccination at age 10 if the hadn't already contracted the virus normally.  Then again, this would probably have a detrimental effect on 'herd' immunity, so it's probably worth it for just that reason.
