The CDC published the Vaccination Coverage Among Children in Kindergarten United States, 2009/10 School Year in the June 3 issue of its MMRW today. Some media outlets picked up the news that Washington has highest vaccine opt-out rate in country. Over 6% of Kindergartners have an exemption for one or more vaccines. While that doesn't seem much at first glance, it does push vaccination coverage at an age where kids are very likely to spread disease under the level that is assumed to be needed for herd immunity. Ironically, in the same issue of the MMWR, the CDC reports two cases of rubella in Washington, one imported, one indigenous.
Honestly? I wonder what sort of false eco-nostalgic ideals Washingtonians are striving for, but is it really those times when hundreds (thousands in epidemic years) of babies per year contracted rubella in the womb and died in utero, or were born with horrendous malformations, deaf, blind, with heart defects?!
Vaccine exemptions lead to disease outbreaks - this is a small example. I wonder how many larger and much more catastrophic examples it will need for some parents to clue in?
