Background Despite recent interest around the impact of social media on COVID-19 vaccine uptake, there has not been a review of social media and adult ‘flu vaccinations. This review aims to look at whether social media interventions can improve ‘flu vaccine knowledge, intention to vaccinate and increase vaccine uptake. Methods We conducted a rapid systematic review of controlled intervention and observational studies that used existing social networks on commercial platforms, such as Facebook and Twitter. Findings Eight studies met our inclusion criteria. Due to heterogeneity in design, studies were thematically analyzed. Employment of influencers, multi-tasking, and the use of a verified source for information can impact positively on vaccine knowledge and intention to vaccinate. Interactions with postings tended to reinforce preconceived ideas. Conclusion Social media interventions can help to improve knowledge about ‘flu vaccine and intention to vaccinate but access to services remain a better determinant of vaccine uptake.
