Videos for Vaccinations
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine which type of video content—informational animations, personal stories, or a mix of both—most effectively encourages older adults to get vaccinated. Researchers will divide participants into groups to watch different video types or none at all. The trial targets U.S. adults aged 50 and older who can watch videos on their devices. As an unphased trial, it offers participants the chance to contribute to important research that could enhance public health messaging for older adults.
Do I need to stop my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these video interventions are safe for increasing vaccination rates among older adults?
Research has shown that both animated and personal story videos are safe and well-received. Studies have found that animated videos can improve perceptions of vaccines without causing negative effects. For instance, a study with over 4,000 participants found these videos enhanced understanding of vaccines, with no reported issues.
Similarly, personal story videos have increased confidence in vaccines. Research found that viewers considered these videos helpful and easy to understand, with no reports of harm. This suggests that both types of videos are safe ways to share vaccine information.12345Why are researchers excited about this trial?
Researchers are excited about the "Videos for Vaccinations" trial because it explores innovative ways to improve vaccine uptake through the power of video storytelling. Unlike traditional methods that rely on written information or direct healthcare provider communication, this trial evaluates how different video formats—informational animations and personal narratives—impact people's decision to get vaccinated. The unique approach combines educational content with engaging personal stories, potentially making vaccine information more relatable and easier to understand. By testing different combinations, such as narrative followed by animation or vice versa, researchers aim to discover the most effective way to influence and motivate people to choose vaccination.
What evidence suggests that this trial's video interventions could be effective in increasing vaccination among older adults?
Research has shown that informational videos can change how people think about vaccines. One study found that 4,076 out of 7,090 unvaccinated individuals chose to get vaccinated after watching videos explaining mRNA vaccines. These videos simplify complex ideas, boosting confidence in vaccination.
In this trial, participants will watch different types of video content. Some will view an informational animation, while others will see a personal narrative video. Videos sharing personal stories are effective because they make information relatable and can improve attitudes toward vaccines. Another study demonstrated that these stories help people understand and overcome vaccine hesitancy, which refers to doubt or fear about vaccines. Both types of videos have increased interest in vaccines, making them promising tools for boosting vaccination rates.14678Who Is on the Research Team?
