Misinformaion and its impact on measles vaccine hesitancy in the pediatric population: A scoping review.

OBJECTIVE

This scoping review is a synthesis of what is known in the literature about the relationship between misinformation and measles, mumps, and rubella (MMR) vaccine hesitancy.

METHODS

A scoping review using Arksey and O'Malley's framework was completed. PubMed, Academic Search Complete, CINHAL, and EBSCOHost were searched for literature published from January 2020 to December 2024 in English on MMR vaccine hesitancy and misinformation.

RESULTS

Initial search resulted in 141 articles. After removing duplicates and articles not meeting inclusion criteria, 23 studies were retained for analysis. Misinformation promulgated in social and religious groups, social media, internet searches, and movies impacted measles vaccine hesitancy. Declining vaccination rates corresponded with circulating social media posts promoting misinformed beliefs towards the MMR vaccine. Interventions targeting vaccine hesitancy have used a variance of communication strategies with limited success. Unfortunately, the COVID-19 pandemic media response decreased institutional trust and increased trust in misinformation, despite evidence to the contrary.

CONCLUSION

Despite scientific demonstration of immunizations benefits, little work has been attempted to understand how and why vaccine decisions are being made, including the effect of misinformation. Research gaps include the pervasiveness of misinformation, the limited efficacy of communication interventions on changing vaccine intention, and the lack of a cohesive theoretical framework.

PRACTICAL IMPLICATIONS: Nurses remain at the crux of vaccination decisions with a unique role in educating parents. Future research should focus on understanding parental MMR vaccine decisions guided by a theoretical framework examining the impact unique social interactions of common beliefs have on decision-making.
