Outbreaks of rubella (measles), mumps, and whooping cough are growing today. This increase is paralleled by the growth of the anti-vaccine movement.

If your sympathies propel you to avoid vaccinations, it probably will not induce you to laugh, though.
PositiveTip: When you stop chuckling, please take your children to get their recommended vaccinations.
