An outbreak of measles in New York City that has spread to at least 20 people has added heat to the debate over the effectiveness of public awareness campaigns and whether the government should strengthen mandatory requirements for children.An outbreak of measles in New York City that has spread to at least 20 people has added heat to the debate over the effectiveness of public awareness campaigns and whether the government should strengthen mandatory requirements for children.
Although the UK saw immunisation rates drop after a now discredited 1998 study by Dr Andrew Wakefield linking the MMR (measles-mumps-rubella) vaccine and autism, the US has not had a significant change.Although the UK saw immunisation rates drop after a now discredited 1998 study by Dr Andrew Wakefield linking the MMR (measles-mumps-rubella) vaccine and autism, the US has not had a significant change.

There are pockets of lower immunisation that could widen, they caution, if autism activists like actresses Jenny McCarthy and Kristin Cavallari continue to push the notion that immunisation is dangerous.There are pockets of lower immunisation that could widen, they caution, if autism activists like actresses Jenny McCarthy and Kristin Cavallari continue to push the notion that immunisation is dangerous.
"You don't need to get every listener to believe that vaccines are Actively Dangerous," writes Alexandra Petra in the Washington Post. "You just need to create an atmosphere that suggests there is Room For Doubt and Debate. Then sit back and watch the vaccination rates drop.""You don't need to get every listener to believe that vaccines are Actively Dangerous," writes Alexandra Petra in the Washington Post.

I do understand that people might have a religious belief against vaccinations. However, I think religious exemptions can and should only go so far. Certainly they stop dead when religion impinges on my rights to have my child attend a school that is safe. I have even less patience for the "personal belief" exemption because that strikes me as being aimed at people who are anti-vaccination. And they are most certainly wrong.I do understand that people might have a religious belief against vaccinations. However, I think religious exemptions can and should only go so far.

"It is a news media-driven misperception that parents who claim philosophical or religious exemptions are uneducated or misinformed," she writes."It is a news media-driven misperception that parents who claim philosophical or religious exemptions are uneducated or misinformed," she writes.
"Most parents who individualize the vaccine schedule are actively educating themselves, continually assessing their family's specific health needs, and doing everything they can to keep their children safe and healthy.""Most parents who individualize the vaccine schedule are actively educating themselves, continually assessing their family's specific health needs, and doing everything they can to keep their children safe and healthy."
So is more money for education the answer? Maybe not. According to a study recently published in Pediatrics medical journal, the more people are warned about the lack of a link between MMR and autism, the more suspicious some parents become that there actually is a link.So is more money for education the answer?

When they gave evidence that vaccines aren't linked to autism, that actually made parents who were already skittish about vaccines less likely to get their child one in the future. When they showed images of sick children to parents it increased their belief that vaccines caused autism. When they told a dramatic story about an infant in danger because he wasn't immunized, it increased parents' beliefs that vaccines had serious side effects.When they gave evidence that vaccines aren't linked to autism, that actually made parents who were already skittish about vaccines less likely to get their child one in the future.

Attempts to educate the public are not "futile", according to Dan Kahan for Yale Law School's the Cultural Cognition Project. The information produced by public health groups has to be carefully crafted, however.

"It is a bad idea to flood public discourse in a blunderbuss fashion with communications that state or imply that there is a 'growing crisis of confidence' in vaccines that is 'eroding' immunization rates," he writes."It is a bad idea to flood public discourse in a blunderbuss fashion with communications that state or imply that there is a 'growing crisis of confidence' in vaccines that is 'eroding' immunization rates," he writes.

Could the immunisation issue really be in danger of becoming another political football? There's a lot wrong with the current US political climate, but at least it hasn't been responsible for an entirely preventable measles epidemic. It would be nice to keep it that way.Could the immunisation issue really be in danger of becoming another political football?
