St George's University London PCV15-PCV20 Infant Vaccinational Trial

Infant vaccination schedule research

St George's University London were researching infant vaccination schedules. They needed to recruit 120 participants. More specifically, these needed to be parents of children who had their 8-week vaccinations upcoming.

We tested running ads on Facebook, Instagram and Google to compare which platform was most effective. We found that Meta was getting more consistent impressions, clicks and expressions of interest, so we re-allocated the budget accordingly. This helps the research team get the most effective results for their budget.

Considering clinical trials involving young children are likely to have a lower conversion rate, the campaign performed well. 11,403 individuals clicked through the ad, and a further 536 of these went on to express their interest in taking part.
