I count myself among those who are confused about the reasons some parents choose not to vaccinate their children against childhood diseases such as measles. But the Wonkblog excerpt [news, Jan. 23], “Clusters of vaccine foes foster spread of illness,” did nothing to persuade me to rally with those who believe in the necessity of vaccination.  

For one thing, of the 34 people who contracted measles and whose vaccination status was known, five were fully vaccinated. What was the status of the others (partially vaccinated, vaccinated in the distant past or totally unvaccinated) and what were their ages?

Furthermore, unlike the climate change and evolution deniers who either have limited information or have arguments based on religious beliefs, the anti-vaxxers, as the article called them, are people who generally are pro-science and highly educated, who have high incomes and who have studied this issue carefully before coming to the conclusion that the risk to their children is greater than the slim possibility of contracting a childhood disease that many in my generation had with little or no residual consequences.
