X (Formerly Twitter) Sees Surge in Vaccine Doubts Post-Covid Rollout

Reading Time: 2 minutes

Negativity surrounding vaccines has surged on X following the availability of Covid vaccines, prompting researchers to advocate for a fresh strategy for addressing vaccine hesitancy.

Insights from the ESCMID Global Congress (formerly ECCMID) in Barcelona, Spain, revealed a significant increase in negative sentiment on the social media platform, particularly coinciding with announcements from governments and healthcare authorities regarding vaccination efforts.

Lead researcher Dr Guillermo Rodriguez-Nava from Stanford University School of Medicine emphasised the importance of rethinking the discourse surrounding vaccines. “Vaccines are one of humanity’s greatest achievements,” Dr Rodriguez-Nava asserted. “They have the potential to eradicate dangerous diseases such as smallpox, prevent deaths from diseases like rabies, and even shield against cancers such as those caused by HPV.”

The analysis, presented at the ESCMID Global Congress, highlighted the detrimental impact of negative messaging on vaccine uptake. Clusters of measles have re-emerged in regions where the disease was previously considered eradicated, illustrating the real-world consequences of vaccine hesitancy.

Dr Rodriguez-Nava and his team conducted a comprehensive analysis of vaccine-related posts on X, employing advanced AI methods for sentiment analysis. The study encompassed tweets with the hashtag “vaccine” from January 2018 to December 2022. Results indicated a predominance of negative sentiment both before and after the introduction of Covid vaccines, with negative tweets outnumbering positive ones.

Negative tweets often expressed distrust in vaccines, with one example calling for the termination of contracts for Covid vaccines and demanding accountability for misinformation spread. Conversely, positive tweets celebrated vaccination milestones, underscoring the importance of immunisation in public health.

Since the advent of Covid vaccines, there has been a notable surge in vaccine-related discourse on X. The platform witnessed an average increase of 10,201 vaccine-related tweets per month compared to pre-vaccination levels. However, alongside this increase came a rise in negativity, with approximately 12,420 negative sentiment tweets per month post-December 2020, representing a 27% increase from expected levels.

The proportion of positive tweets decreased slightly, while negative tweets saw a corresponding uptick after the introduction of Covid vaccines. Moreover, spikes in negative activity were observed in conjunction with significant announcements related to vaccination efforts. For instance, April 2021 saw a peak in negative tweets, coinciding with the announcement of Covid vaccine eligibility for all individuals aged 16 and older by the White House.

Interestingly, April 2022 witnessed a decline in negative tweets, corresponding with the acquisition of X by Elon Musk. While the exact reason behind this decline remains unclear, potential factors include seasonal patterns or user focus on platform changes under new ownership.

In response to these findings, researchers underscored the need for a revamped approach to vaccine communication. Dr. Rodriguez-Nava stressed the importance of refraining from derogatory terms such as “anti-vaxxers” and fostering a more respectful dialogue with vaccine-hesitant individuals. Collaboration with social media influencers, religious leaders, and lawmakers was also recommended to amplify positive vaccine messaging.

The role of social media platforms in combating vaccine misinformation was highlighted. Dr. Rodriguez-Nava urged social media companies to take proactive measures to address vaccine-related misinformation, while acknowledging the complexity of balancing free speech with public health interests.

As vaccine hesitancy continues to pose challenges to global immunisation efforts, initiatives aimed at promoting vaccine acceptance and combating misinformation on platforms like X are crucial to safeguarding public health.
