Vaccipack, A Mobile App to Promote Human Papillomavirus Vaccine Uptake Among Adolescents Aged 11 to 14 Years: Development and Usability Study.
Anne M Teitelman, Emily F Gregory, Joshua Jayasinghe and 6 others
PMID 34345789WHAT IT FOUND
Parents and adolescents found the Vaccipack app easy to use and intended to use it to track HPV vaccines.
However, this was a usability test, not a trial, so it does not prove the app increases actual vaccination rates.
Key findings
01Most parents (88%) and adolescents (75%) intended to use the app within two weeks after being introduced to it.
02Parents and adolescents rated the app as easy to learn and use, with parents finding it easier to learn than adolescents did.
03The app was designed to address parental beliefs about HPV vaccine safety, cost, and provider recommendations through stories and tracking features.

What it does not show
The study was conducted at a single periurban clinic in the northeastern United States, so results may not apply to rural or other geographic settings. The sample was predominantly White (79% of parents) and high-income (65% of families earned over $80,000), limiting generalizability to more diverse populations. The study measured intention to use and acceptability, not actual long-term use or impact on HPV vaccination rates. Adolescents found the app harder to learn than parents did, suggesting the design may need adjustment for teen users.
Declared interests
One coauthor (KAF) is currently an employee of Merck & Co, Inc, but the study was conducted and the manuscript submitted prior to this employment. The authors state that KAF's participation was independent of Merck.
The easy way to misread this
Do not interpret the high intention to use as evidence that the app increases HPV vaccination rates. This was a usability and acceptability study, not a randomized trial measuring clinical outcomes.
