Factors underlying parental decisions about combination childhood vaccinations including MMR: a systematic review

Area of Science:

• Public Health
• Immunization
• Behavioral Science

Background:

• Suboptimal childhood vaccination uptake contributes to preventable disease outbreaks.
• Parental vaccine decisions are a significant factor in developed countries.
• Understanding these decisions is crucial for developing effective public health interventions.

Purpose of the Study:

• To systematically review factors influencing parental decisions regarding childhood vaccinations.
• To identify key attitudes and beliefs associated with vaccine hesitancy.
• To inform the design of evidence-based interventions to improve vaccination uptake.

Main Methods:

• Systematic review of 31 studies examining parental vaccination decisions.
• Analysis of factors underlying vaccine acceptance and refusal.
• Synthesis of disparate outcomes and methodologies to identify consistent themes.

Main Results:

• Parents' attitudes towards vaccine safety, efficacy, and disease severity strongly influence uptake.
• Vaccine-hesitant parents often distrust official sources but trust media and anecdotal information.
• Perceived pressure for public health benefit, rather than individual child safety, is a point of contention.

Conclusions:

• Interventions should target specific decision-making processes, including anticipated regret and the perception of anecdotal evidence.
• Addressing parental mistrust in health professionals and government is essential.
• Methodological improvements in research, such as reliable uptake measures, are needed for more robust data.
