I have a new paper with Ang Li (reseachgate here) just published in Preventive Medicine on the impact of No Jab, No Pay and No Jab, No Play on vaccine coverage rates.
We found that these policies, which removed non-medical exemptions from government benefits and childcare enrolments, were occasioned by an increase in vaccination coverage across states between 2-4% for one-year olds, 1-1.5% for two-year olds, and 1-3.5% for five-year-olds.
We also found that the effect of the policy differed significantly depending on
characteristics of the area.
Areas that were characterised by either: lower socio-economic status, lower median income, more Family Tax Benefit recipients, or higher pre-intervention coverage had
greater responsiveness to the policy changes.
Variation in response to the policy changes across areas suggest the effect was largely
led by lower-socioeconomic status parents who were nudged towards full
vaccination, while more affluent parents were relatively unaffected.
Hightlights:
- Removing conscientious objection
increased overall childhood vaccination coverage.
- The policy responses were
heterogeneous.
- Socioeconomically advantaged areas
were less responsive to policy changes.
- Benefit-dependent and lower-income
areas were more responsive to policy changes.
- Areas with pre-existing low
coverage were more persistent and less responsive.
Abstract: Vaccine
refusal and hesitancy pose a significant public health threat to communities.
Public health authorities have been developing a range of strategies to improve
childhood vaccination coverage. This study examines the effect of removing
conscientious objection on immunisation coverage for one, two and five year
olds in Australia. Conscientious objection was removed from immunisation
requirement exemptions for receipt of family assistance payments
(national No Jab No Pay) and enrolment in childcare (state No
Jab No Play). The impact of these national and state-level policies is
evaluated using quarterly coverage data from the Australian Immunisation
Register linked with regional data from the Australian Bureau of Statistics at
the statistical area level between 2014 and 2018. Results suggest that there
have been overall improvements in coverage associated with No Jab No
Pay, and states that implemented additional No Jab No Play and
tightened documentation requirement policies tended to show more significant
increases. However, policy responses were heterogeneous. The improvement in
coverage was largest in areas with greater socioeconomic disadvantage, lower
median income, more benefit dependency, and higher pre-policy baseline
coverage. Overall, while immunisation coverage has increased post removal of
conscientious objection, the policies have disproportionally affected lower
income families whereas socioeconomically advantaged areas with lower baseline
coverage were less responsive. More effective strategies require investigation
of differential policy effects on vaccine hesitancy, refusal and access
barriers, and diagnosis of causes for unresponsiveness and under-vaccination in
areas with persistently low coverage, to better address areas with persistent non-compliance
with accordant interventions.
