Table 2 Summary of differences between complete, incomplete and non-immunisers* in terms of the Health Belief Model

From: Making sense of perceptions of risk of diseases and vaccinations: a qualitative study combining models of health beliefs, decision-making and risk perception

  Severity Susceptibility Benefits Barriers Cues to action
Complete immuniser Diseases serious, better to be prevented Likely to get diseases Vaccines are safe & effective Lack of information about vaccines, diseases & side effects Have health provider one can trust
    Serious side effects are rare   
Incomplete immuniser Better to get either the vaccine or the disease when young (for some diseases) Children susceptible to diseases/sickness in general ('they are always sick') Vaccines are safe but not effective Minor illnesses, forgetting, advice from health professionals School immunisation certificate (but not for age-appropriate immunisations)
  Diseases are serious for adults Adults more likely to have serious side effects from measles, rubella, mumps Vaccines wont prevent diseases but will reduce effects Confusion about which vaccines have been given Health provider who understands family's circumstances
Non-immuniser Diseases are not as serious as made out especially if child has healthy immune system Susceptible to vaccine side effects Vaccines cannot prevent diseases & are actively dangerous Perceived serious consequences of vaccines None
Common perceptions Measles is common but rarely serious Very young children are susceptible to vaccine side effects None Lack of information, trust, support Trusted health provider and/or information
  Other diseases are serious but not common     
  1. *3 Partial immunisers held views similar to complete immunisers and the other 4 held similar views to non-immunisers
