Background: The development of COVID-19 vaccines has been crucial in fighting the pandemic. However, misinformation about the COVID-19 pandemic and vaccines is spread on social media platforms at a rate that has made the World Health Organization coin the phrase infodemic. False claims about adverse vaccine side effects, such as vaccines being the cause of autism, were already considered a threat to global health before the outbreak of COVID-19. Objective: We aimed to synthesize the existing research on misinformation about COVID-19 vaccines spread on social media platforms and its effects. The secondary aim was to gain insight and gather knowledge about whether misinformation about autism and COVID-19 vaccines is being spread on social media platforms. Methods: We performed a literature search on September 9, 2021, and searched PubMed, PsycINFO, ERIC, EMBASE, Cochrane Library, and the Cochrane COVID-19 Study Register. We included publications in peer-reviewed journals that fulfilled the following criteria: original empirical studies, studies that assessed social media and misinformation, and studies about COVID-19 vaccines. Thematic analysis was used to identify the patterns (themes) of misinformation. Narrative qualitative synthesis was undertaken with the guidance of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 Statement and the Synthesis Without Meta-analysis reporting guideline. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal tool. Ratings of the certainty of evidence were based on recommendations from the Grading of Recommendations Assessment, Development and Evaluation Working Group. Results: The search yielded 757 records, with 45 articles selected for this review. We identified 3 main themes of misinformation: medical misinformation, vaccine development, and conspiracies. Twitter was the most studied social media platform, followed by Facebook, YouTube, and Instagram. A vast majority of studies were from industrialized Western countries. We identified 19 studies in which the effect of social media misinformation on vaccine hesitancy was measured or discussed. These studies implied that the misinformation spread on social media had a negative effect on vaccine hesitancy and uptake. Only 1 study contained misinformation about autism as a side effect of COVID-19 vaccines. Conclusions: To prevent these misconceptions from taking hold, health authorities should openly address and discuss these false claims with both cultural and religious awareness in mind. Our review showed that there is a need to examine the effect of social media misinformation on vaccine hesitancy with a more robust experimental design. Furthermore, this review also demonstrated that more studies are needed from the Global South and on social media platforms other than the major platforms such as Twitter and Facebook.

The aim of this study was to explore how autistic adults experienced using social media to find information about autism, and how they experienced online autistic communities. There is little research on the rationale why autistic people look for information on autism via social media, and on how such information is perceived from an autistic viewpoint. Twelve Norwegian autistic adults (aged 18–49 years) completed semi-structured interviews where they discussed social media and content specifically about autism and online autistic communities. Using reflexive thematic analysis, three main themes were developed. The themes were (1) Representation and Identity: An Online Journey; (2) An Unreliable, but Necessary Tool; and (3) Tensions and Discord. The findings indicated that even though social media was looked upon as an unreliable information source, the participants found information that helped them to learn about their experiences which had not been fully captured by the majority of the current research literature and online health sites. Also, social media groups for autistic people did not necessarily create a sense of community, as participants reported feeling alienated by hostile discussions. This study highlights the importance of having a greater variation and availability of information about autism online through official health channels. Lay This study suggested that social media can provide important information about autism to autistic people. We interviewed 12 autistic adults (aged 18–49 years) and talked to them about the use of social media to find both general information and content specifically about autism, autism identity and online autistic communities. There is little research exploring how autistic people find information about autism on social media and how that makes them feel. Therefore, it is important to ask autistic people about their experiences with using social media to obtain content about autism. The 12 participants explained that when they searched for information about autism on the official health pages, they often felt that the information they found was insufficient and could not answer their questions. In addition, they searched on social media platforms for information about autism despite that they perceived social media as an unreliable source. On the social media platforms, many found content that was positive in relation to their autistic identities. The participants also found comfort in some of the forums and social media groups and received helpful advice. Nevertheless, some of the discussions were aggressive and the participants felt alienated, which did not provide a sense of community online. The findings from the study may advice on what is missing in the official pages about autism, and highlight the need to involve the autistic community in writing the content on such platforms.

An increasing number of students with autism spectrum disorder (ASD) enroll in inclusive schools and classrooms. The aim of this study was to research how students with ASD experience the social aspect of inclusive high schools. Five adolescences with Asperger syndrome were interviewed, and the results show that high school was perceived as an important platform for social training, and an equally important place to find new friends and acquaintances. A majority of the participants had experienced loneliness and bullying in junior high school. However, they experienced high school as a new start, with a more open and inclusive environment. Nevertheless, several of the participants expressed that they used quite a lot of energy on social settings, such as interpreting social situations and on being amongst a larger group of students. In order to support this group of adolescents in their schooling, it is important to look at their strength and resources, and not only focus on the challenges and difficulties.

The purpose of this study was to examine Internet trends data and sentiment in tweets mentioning autism, Asperger syndrome, and Greta Thunberg during 2019. We used mixed methods in analyzing sentiment and attitudes in viral tweets and collected 1074 viral tweets on autism that were published in 2019 (tweets that got more than 100 likes). The sample from Twitter was compared with search patterns on Google. In 2019, Asperger syndrome was closely connected to Greta Thunberg, as of the tweets specifically mentioning Asperger (from the total sample of viral tweets mentioning autism), 83% also mentioned Thunberg. In the sample of tweets about Thunberg, the positive sentiment expressed that Greta Thunberg was a role model, whereas the tweets that expressed the most negativity used her diagnosis against her and could be considered as cyberbullying. The Google Trends data also showed that Thunberg was closely connected to search patterns on Asperger syndrome in 2019. The study showed that being open about health information while being an active participant in controversial debates might be used against you but also help break stigmas and stereotypes.

Background: On May 8, 2021, Elon Musk, a well-recognized entrepreneur and business magnate, revealed on a popular television show that he has Asperger syndrome. Research has shown that people’s perceptions of a condition are modified when influential individuals in society publicly disclose their diagnoses. It was anticipated that Musk's disclosure would contribute to discussions on the internet about the syndrome, and also to a potential change in the perception of this condition. Objective: The objective of this study was to compare the types of information contained in popular tweets about Asperger syndrome as well as their engagement and sentiment before and after Musk’s disclosure. Methods: We extracted tweets that were published 1 week before and after Musk's disclosure that had received >30 likes and included the terms “Aspergers” or “Aspie.” The content of each post was classified by 2 independent coders as to whether the information provided was valid, contained misinformation, or was neutral. Furthermore, we analyzed the engagement on these posts and the expressed sentiment by using the AFINN sentiment analysis tool. Results: We extracted a total of 227 popular tweets (34 posted the week before Musk’s announcement and 193 posted the week after). We classified 210 (92.5%) of the tweets as neutral, 13 (5.7%) tweets as informative, and 4 (1.8%) as containing misinformation. Both informative and misinformative tweets were posted after Musk’s disclosure. Popular tweets posted before Musk’s disclosure were significantly more engaging (received more comments, retweets, and likes) than the tweets posted the week after. We did not find a significant difference in the sentiment expressed in the tweets posted before and after the announcement. Conclusions: The use of social media platforms by health authorities, autism associations, and other stakeholders has the potential to increase the awareness and acceptance of knowledge about autism and Asperger syndrome. When prominent figures disclose their diagnoses, the number of posts about their particular condition tends to increase and thus promote a potential opportunity for greater outreach to the general public about that condition.

The development of COVID-19 vaccines has been crucial in fighting the pandemic. Misinformation about COVID-19 vaccines on social media is a major challenge, as this is thought to contribute to vaccine hesitancy. Here, we review the research on misinformation about COVID-19 vaccines spread on social media platforms. The review is registered with the PROSPERO international register of systematic reviews (CRD42021277524). We performed a literature search on 9 September 2021 and searched PubMed, PsycINFO, ERIC, Embase, Cochrane Library, and the Cochrane COVID-19 Study Register. We included publications in peer-reviewed journals that fulfilled all following criteria: Original empirical studies, studies that assessed social media and misinformation, studies that dealt with vaccine hesitancy, and studies about the COVID-19 vaccine. Publications were excluded if data were gathered before Phase III in the first COVID-19 vaccine development (from July 27 2020 to November 13, 2020). The narrative qualitative synthesis was undertaken with the guidance of the PRISMA 2020 Statement and the Synthesis Without Meta-analysis reporting guideline. The risk of bias was assessed according to The Joanna Briggs Institute (JBI) Critical Appraisal tool. Ratings of the certainty of evidence were based on recommendations from the GRADE Working Group. The search amounted to 757 records, with 45 articles selected for the review. There are many types of misinformation that are spread on social media platforms. We identified three main areas of misinformation: Medical misinformation, vaccine development, and conspiracies. To prevent these misconceptions from taking hold, health authorities should openly address and discuss these false claims with both cultural and religious awareness in mind. Our review showed that there is a need to examine the effect of social media misinformation on vaccine hesitancy with a more robust experimental design. Furthermore, our review also demonstrated that more studies are needed from the Global South and on other social media platforms than the major platforms such as Twitter.
