Introduction Early childhood is associated with multiple health concerns and the risks of disorders and infectious diseases. Challenges that can make parents more cautious are young children’s limited ability to realize and explain their issues and the tremendous influence of health information from non-authoritative sources. This paper discusses two case studies in which outside influences on parents’ immunization decisions and complex issues in toddlers are illustrated. Key Health Issues In this case, two health issues, including the new mother’s vaccine hesitancy and missed four-month vaccinations for the six-month-old infant, are introduced. The woman’s hesitancy about the safety of child immunization as per the approved national schedule stems from the exposure to information about links between vaccination and autism spectrum disorder (ASD). Regarding the next issue, based on Australia’s immunization schedule, the child has already missed immunizations against diphtheria, tetanus, hepatitis B, pertussis, rotavirus, and pneumococcal infections (Australian Government, Department of Health, 2021). This situation creates the need for subsequent health assessments and measures to prevent missed immunizations from increasing the child’s susceptibility to the listed conditions. Issue Management Strategies The first issue should be managed by employing parent education. As current research suggests, anti-immunization messages from mass media sources are positively correlated with immunization hesitancy attitudes among families (Bianco et al., 2019). Worse still, this client’s distrust of the national healthcare system is exacerbated by the case of her niece or nephew diagnosed with autism after immunization, which is an example of a post hoc fallacy. Firstly, the client is to receive education on the importance of immunization for protecting the child against poorly treatable and life-threatening conditions concerning statistics regarding disease in immunized and non-immunized children. Secondly, due to the client’s specific concerns about ASD, it is critical to gather information from trustworthy sources of health-related information, including peer-reviewed research and documents from the World Health Organization, to dispel the myths about child vaccination in an educational conversation (Geoghegan et al., 2020). Finally, it will be made explicit to the mother that her child will be denied child care services as per the New South Wales immunization policy (New South Wales Government, 2021). After the education, she will be encouraged to make an informed choice. The problem related to missed four-month vaccinations will be handled using risk assessment interventions. Since the immunization requirements are slightly different for Indigenous and non-Indigenous Australians and high-risk conditions, the nurse will gather information about the child’s ethnicity and risk conditions for pneumococcal disease and other diseases mentioned above (Australian Government, Department of Health, 2021). Using this information and the details of the child’s medical history, the professional will determine the high-risk conditions stemming from missed immunizations and schedule a comprehensive physical assessment. Apart from deviations from the immunization schedule, risk factors for the diseases for which the immunizations have been m
