BACKGROUND A coronavirus vaccine that works is considered a game-changer in the battle against the unprecedented pandemic. News and social media discussions have been extensively covered the issue of coronavirus vaccines, with a mixture of advocacies, concerns, rumors and conspiracy theories. OBJECTIVE This study aims to uncover the emerging themes in social media discussions regarding the potential coronavirus vaccines. METHODS This study employ topic modelling to analyze Tweets related to coronavirus vaccines at the start of the COVID-19 in the United States (February 21 to March 20, 2020). We created a predefined query (e.g., "COVID" AND "vaccine") to extract the tweet text and metadata (number of followers of the Twitter account and engagement metrics based on likes, comments and retweeting) from the Meltwater database. After pre-processing the data, we tested Latent Dirichlet Allocation models with different solutions for identifying topics associated with tweets. The topic model with 20 topics provided the best topic coherence, and each topic was interpreted based on its top associated terms. RESULTS In total, we analyzed 100,209 tweets related to coronavirus vaccines. The 20 topics were further collapsed based on their similarities, resulting in seven big themes. Our analysis characterized 26.3% of the tweets as News Related to Coronavirus and Vaccine Development, 25.4% as General Discussion and Information Seeking of Coronavirus, 12.9% as Financial Concerns, 12.7% as Venting Negative Emotions, 9.9% as Prayers and Call for Positivity, 8.1 as Efficacy of Vaccine and Treatment and 4.9% as Conspiracies. Different themes demonstrated some changes over time, mostly in a close association with news or events related to the progress of vaccine developments. Users with a large number of followers (also known as key opinion leaders) preferred to discuss the themes of conspiracy theories, efficacy of vaccines and treatments, and financial concerns over other themes. The engagement levels of different themes were similar except for venting negative emotions. CONCLUSIONS This study concluded that financial concerns emerged as one important concern among the public regarding the potential coronavirus vaccines. The discussions of vaccines considerably mixed with political discussions, which suggests that the issue of coronavirus vaccines is politicized in the US. Only a small proportion of tweets were concerned about conspiracy theories, but their impact can be amplified by key opinion leaders and its relatively higher engagement level with the audiences.

There is a gap between the optimal and the current utilization of radiotherapy in Europe: the ESTRO Cancer Foundation (ECF) was set-up to support ESTRO in tackling the barriers preventing patients to receive the treatment they need. The ECF aims at creating value for multiple stakeholders - patients, healthcare professionals and national societies, decision makers. The value creation will be captured in a virtuous circle: the ECF builds up on the ESTRO knowledge base and activities, while ESTRO research outcomes will be better accessible to external publics. The key success factors of the ECF are the engagement of the corporate partners and the synergies with the ESTRO activities: both are instrumental for the sustainability of the ECF. The Marie Curie Legacy campaign is the first project of the ECF. Leveraging on the 150th anniversary of Marie Curie's birth, it raises awareness on radiotherapy, and is based on the ESTRO toolkit for radiotherapy advocacy. The 7th November marked the launch of the campaign at European level, with an animation commemorating the legacy Marie Curie left to radiotherapy. The campaign was then led in a few European countries: in Belgium and Poland national key opinion leaders, selected in agreement with national RT societies, voiced the benefits of RT through interviews in traditional media. More countries will be targeted in 2018. With a 6 weeks campaign using social media the video was viewed by 250,000 viewers in YouTube only, and in full length by more than 60,000 viewers. In Belgium, the media campaign run for 2 days, obtaining 25 clippings, with headlines on traditional media and primetime on TV channels. In Poland, the campaign and video were launched in occasion of the World Cancer Day. The social media push of the video with subtitles ensured 125,000 views. The traditional media campaign, in one week, obtained 155 online and printed articles. The campaign, combining an European approach and national deployments, is an instrument for the European society to empower the national societies in the positioning of RT in their countries. The animation video proved to be an excellent hook to attract attention, while the engagement of national key opinion leaders is necessary for the overall success of the campaign, health remaining a national matter. Targeting the content is essential: radiotherapy is impersonated by Marie Curie in the animation, while in the national campaigns where the messages are also directed to decision makers, radiotherapy is impersonated by national experts. Overall, the process of raising awareness initiated by the ECF requires strong synergies with ESTRO activities, to ensure a two ways street: the ECF projects ensure that the benefits of radiotherapy treatment are better known, and ESTRO activities can capture the value created, by fostering radiotherapy: securing investments in radiotherapy resources, providing education, creating a more favorable policy environment, advancing research.

Despite an increasing information overflow in the era of digital communication, influencers manage to draw the attention of their followers with an authentic and casual appearance. Reaching large audiences on social media, they can be considered as digital opinion leaders. In the past, they predominantly appeared as experts for topics like fashion, sports, or gaming and used their status to cooperate with brands for marketing purposes. However, since recently influencers also turn towards more meaningful and political content. In this article, we share our perspective on the rise of political influencers using examples of sustainability and related topics covered on Instagram. By applying a qualitative observational approach, we illustrate how influencers make political communication look easy, while at the same time seamlessly integrating product promotions in their social media feeds. In this context, we discuss positive aspects of political influencers like contributions to education and political engagement, but also negative aspects such as the potential amplification of radical political ideology or conspiracy theories. We conclude by highlighting political influencers as an important research topic for conceptual and empirical studies in the future.
