Consent and public engagement in an era of expanded childhood immunisation

Childhood immunisation programmes have seen well-heralded successes in disease control. An increasing number of scheduled vaccines, narrowing risk-benefit ratios and public attention to vaccine safety raise new questions about consent. We first explore the challenges that this highly dynamic environment poses for valid consent. Then, we broaden this discussion to wider public engagement by suggesting how the public - the bearers of vaccine risk and benefit - can be better involved in immunisation policy.
