Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study aims to alter how people view potential COVID-19 vaccination side effects through the use of a brief mindset intervention that frames symptoms as positive signals that the body is responding to the COVID-19 vaccination. Recent research has shown that changing patient mindsets can positively impact both the meaning and experience of side effects. Participants will be randomized to view a specifically made brief 5 minute video on an electronic tablet about the meaning of COVID-19 side effects and how they are often positive signals that the vaccine is bolstering the immune system or receive the standard information. This will be administered in the 30- minute wait period post their first COVID-19 vaccination. Side effects will be assessed at the end of the waiting period following the first vaccine and three days later. We will also assess side effects following the second vaccination in both groups. We hypothesise that this mindset intervention will decrease side effect reporting and improve the experience of any side effects experienced, resulting in less distress for the individual.

Behaviour
Comparator / control treatment
The control group will not be given the intervention video, but respond to the same measures. the information they will be responding about is the standard information as received by medical professionals on the day of their vaccination. There is no specifically designed standard information for this group, more so a TAU approach.
