Childhood vaccination continues to be one of the most cost‐effective health policy interventions. All OECD countries or, in some cases, sub‐national jurisdictions have established vaccination programmes based on their interpretation of the risks and
benefits of each vaccine. Coverage of these programmes can be considered as a quality of care indicator. Pertussis, measles and hepatitis B are taken here as examples as they represent in timing and frequency of vaccination the full spectrum of organisational challenges
related to childhood vaccination.
