The impact and feasibility of the intervention was evaluated in a prospective randomised controlled feasibility trial.Results A total of 49 parent-daughter dyads completed baseline knowledge assessment (n=24 control, n=25 intervention), and 35 dyads completed knowledge assessment at week 2 (n=17 control, n=18 intervention). The intervention was associated with a statistically significant increase in HPV, and HPV vaccine knowledge and intention to vaccinate. All intervention participants found the video interesting, while 96% found it useful.Conclusions This intervention was found to be affordable, practicable, effective (cost-effective), acceptable, safe, and equitable, in this feasibility study.Competing Interest StatementThe authors have declared no competing interest.
