FA16 Immunization Module’s Updates

Social hurdles for administering vaccines: Why aren't we vaccinating?

Recently, we have seen the discussion around vaccination in the US pit many physicians against the 'anti-vaxxer' movement, a group of parents that cross traditional political-economic divides in opposing vaccination, which they consider unsafe or an overstep of government control.

The conversation often turns vitriolic, with physicians and others lobbing educations of ignorance and stupidity at parents, while those same parents grow increasingly hesitant to comply with instructions from a medical community they believe does not respect them.

How do we, as future physicians, change the conversation to improve education and ensure public immunity? It is not as simple as winning the shouting match, which actually may be impossible. And, in fact, that may not be the main hurdle in improving overall public immunity.

This longitudinal study published in 2015 of a study of 5,000 Australian children (which I could not find replicated among American children), gives some critical insight: Only 16% of the children that were not immunized were because of parental disagreement. Overwhelmingly, the study found, non-compliance in immunization is attributed to four other ‘classes’ of issues: “(1) ‘lone parent, mobile families with good support’, (2) ‘low social contact and service information; psychological distress’, (3) ‘larger families, not using formal childcare’, (4) ‘child health issues/concerns’” [1]. The first three of these are all related to the socioeconomic position of families and, understandably, their understanding about immunizations and ability to access those immunizations. The study goes on to say that “the adjusted risk ratio (RR) for incomplete immunization was 1.51 (95% confidence interval: 1.08–2.10) among those characterized by ‘low social contact and service information; psychological distress’, and 2.47 (1.87–3.25) among ‘larger families, not using formal childcare’” [1] – that is to say that we must maximize our interventions for the highest risk individuals in order to see the greatest increase in public immunization.

Clearly, this is not just about the ultra-wealthy of Marin County, CA embracing ‘natural’ over allopathic medicine. It is a much larger endemic problem closely tied to lack of access to healthcare.

As physicians, it will not be enough for us to simply tell our patients to get their children immunized. A study published by the WHO in 2012 recommends that “Every program should monitor missed and under-vaccinated children and assess and address the causes” [2], which it draws from researching the underlying causes of missed immunizations, which are very heterogeneous and regionally variable. As physicians, we are our patient’s advocates, and must be cognizant of the institutionalized class barriers to childhood immunization. Part of our job will be to make it clear, simple, and low-cost for families to get their children immunized.
