Characterizing Responses to COVID-19 Vaccine Promotion on TikTok

Abstract

Purpose

The Alabama Department of Public Health (ADPH) sponsored a TikTok contest to improve vaccination rates among young people. This analysis sought to advance understanding of COVID-19 vaccine perceptions among ADPH contestants and TikTok commenters.

Approach

This exploratory content analysis characterized sentiment and imagery in the TikTok videos and comments. Videos were coded by two reviewers and engagement metrics were collected for each video.

Setting

Publicly available TikTok videos entered into ADPH’s contest with the hashtags #getvaccinatedAL and #ADPH between July 16 – August 6, 2021.

Participants

ADPH contestants (n = 44) and TikTok comments (n = 502).

Method

A content analysis was conducted; videos were coded by two reviewers and engagement metrics was collected for each video (e.g., reason for vaccination, content, type of vaccination received). Video comments were analyzed using VADER, a lexicon and rule-based sentiment analysis tool).

Results

Of 44 videos tagged with #getvaccinatedAL and #ADPH, 37 were related to the contest. Of the 37 videos, most cited family/friends and civic duty as their reason to get the COVID-19 vaccine. Videos were shared an average of 9 times and viewed 977 times. 70% of videos had comments, ranging from 0-61 (mean 44). Words used most in positively coded comments included, “beautiful,” “smiling face emoji with 3 hearts,” “masks,” and “good.;” whereas words used most in negatively coded comments included “baby,” “me,” “chips,” and “cold.”

Conclusion

Understanding COVID-19 vaccine sentiment expressed on social media platforms like TikTok can be a powerful tool and resource for public health messaging.
