More below about the rationale for state funding of vaccination injury compensation
The public health benefits of vaccination are clear. The World Health Organization estimates that, in 2008, more than 2.5 million deaths were prevented by vaccination.1 Immunization programmes have led to the eradication of smallpox, the elimination of measles and poliomyelitis in many regions, and substantial reductions in morbidity and mortality from Haemophilus influenzae type b, diphtheria, whooping cough and tetanus. However vaccines are not without risks and it is commonly accepted that, regardless of proper design, manufacture and delivery, adverse events occur following vaccination although serious adverse events are rare.2
At a population level, it is considered that these small risks are balanced by the benefits of widespread population immunization. However this means that an individual occasionally bears a significant burden for the benefit provided to the rest of the population. Although these vaccine-related adverse events occur occasionally due to negligence, more often there is no clearly attributable fault.
Without evidence of clear negligence, it is difficult to obtain compensation through traditional legal mechanisms. Recognizing this, several countries have implemented vaccine-injury compensation programmes.3 These programmes reflect a belief that it is fair and reasonable that a community that is protected by a vaccination programme accepts responsibility for and provides compensation to those who are injured by it.
