Monica Anderson – “As the number of measles cases linked to the California outbreak climbs to over 100, health officials are urging parents to properly immunize their children, citing unvaccinated individuals as a main contributor to the disease’s spread. Some have linked the outbreak to the anti-vaccination movement – a group whose members claim vaccinations are unsafe and ineffective. A Pew Research Center report released last week shows that a majority of Americans say children should be required to get vaccinated. Further analysis of the survey data reveals significant age differences in views about vaccines. In 2009, by contrast, opinions about vaccines were roughly the same across age groups. Also, some modest partisan divisions have emerged since 2009, when Pew Research last polled on the issue. Overall, 68% of U.S. adults say childhood vaccinations should be required, while 30% say parents should be able to decide. Among all age groups, young adults are more likely to say vaccinating children should be a parental choice. Some 41% of 18- to 29-year-olds say parents should be able to decide whether or not their child gets vaccinated; only 20% of adults 65 or older echo this opinion.”
