Summary: By surveying adolescents and their parents, we found that parental concerns about vaccine safety increased significantly before and after the availability of the COVID-19 vaccine. Social media negatively influenced opinions about vaccine safety. Demographic variables were associated with vaccination rates, highlighting inequalities in vaccine access. Most parents supported simultaneous COVID-19 vaccination with other vaccines. Addressing vaccine hesitancy is crucial for increasing COVID-19 vaccine coverage rates.

Summary: Vaccine hesitancy is a major barrier to vaccination, especially among neurodivergent individuals, who face a higher risk of hospitalization and mortality from COVID-19. Misinformation, perception of vaccine risk, sensory sensitivities, and structural hardship are identified as significant barriers to COVID-19 vaccination.

Summary: This study identified public sentiments and opinions towards COVID-19 vaccines on Twitter, showing a dominance of positive sentiments but active discussions on vaccine rejection and hesitancy. Different countries exhibited varying patterns. Additionally, the study found that vaccine opposition content came partly from Twitter bots or political activists, while support for vaccination originated from well-known individuals and organizations.

Summary: Approximately 80% of adults in Philadelphia are fully vaccinated against Covid-19, but many zip codes in the city have significantly lower vaccination rates, particularly in marginalized communities with residents of color and high poverty levels. In-depth interviews with representatives from 15 community-based organizations were conducted to understand the reasons behind the low vaccination rates and to evaluate strategies for promoting vaccination. The qualitative analysis revealed that vaccine postponement, rather than refusal, is a result of distrust towards the vaccine, government, and healthcare system, as well as more urgent concerns such as work, cost, and identification issues. The findings shed light on lesser discussed reasons for vaccination delays and offer insights for promoting vaccinations during the current pandemic and future efforts.

Summary: During the COVID-19 pandemic, social media content analysis has been used to track attitudes towards vaccines. This study compares the arguments used by anti-vaxxers on different social media platforms. The findings show that anti-vaxxers use different categories of arguments across platforms, with Facebook and Twitter focusing on government distrust and vaccine safety and effectiveness, TikTok focusing on personal freedom, and Instagram facing criticism for advocating vaccination.

Summary: This study aimed to evaluate the effectiveness of a culturally tailored outreach intervention designed to increase SARS-CoV-2 testing rates among Latinx populations. The results showed that the intervention tested 3.84 times more Latinx individuals per event than the control group and increased the proportion of tested Latinx population by 0.28. These findings could inform strategies to reduce other health disparities experienced by these groups.

Summary: The study aimed to investigate how pregnant women obtain information about COVID-19 and vaccination. The online questionnaire survey revealed that age, occupation, and infection-risk anxiety influenced the choice of media for information seeking. Older pregnant women, medical professionals, public servants, and educators were more likely to rely on specialized medical websites, while housewives tended to use mass media, social media, and sources with uncertain scientific evidence. The gestational weeks and method of conception also impacted the media selection. The accessibility of COVID-19 information for pregnant women was determined by their social background and pregnancy status. Efforts should be continued to ensure that appropriate information is readily available to pregnant women and their families.

Summary: Trust in institutions and democracy plays a significant role in COVID-19 vaccine acceptance. The study found that factors such as trust in institutions, trust in non-pharmaceutical interventions, and various demographic factors were associated with intent to vaccinate. History of influenza vaccination and satisfaction with democratic institutions were highly predictive of COVID-19 vaccine acceptance. Results also showed that social determinants of health and receiving the flu vaccine were predictors of COVID-19 vaccine acceptance.

Summary: This community case study explores how information about COVID-19 safety and vaccination was delivered to a former refugee community in regional Victoria. Community outreach and codesign approaches established closer engagement, leading to increased understanding and compliance with COVID-19 safe messages and vaccination uptake. Community-led innovations, such as COVID-19 fact sheets and videos in the Karen language and the establishment of a COVID-19 information hotline, supported the delivery of vaccination clinics and further increased community participation.

Summary: This study found that 20% of the population in Qatar is hesitant towards the COVID-19 vaccine, with concerns around safety and long-term side effects being the main reasons. Citizens and females were more likely to be hesitant, and personal research was identified as an important factor in increasing confidence in vaccine acceptance.

Summary: The study found that states in the southern U.S. had a significantly higher proportion of negative tweets towards COVID-19 vaccines compared to other regions, while higher-income states reported lower proportions of negative tweets. These results indicate the presence of geographic variability in vaccine sentiments, highlighting the need for tailored vaccine promotion strategies.

Summary: Vaccine hesitancy is a complex issue that can hinder vaccine coverage expansion. This study analyzed vaccine hesitancy expressed on social media and found that it is volatile and constantly changing. Government strategies to counteract vaccine hesitancy should be agile and address the varying arguments expressed by individuals who are hesitant.

Summary: This study investigated the adverse effects associated with three different COVID-19 vaccines and found that local reactions were more common with Pfizer and AstraZeneca vaccines, while systemic events were more prevalent with AstraZeneca and Pfizer vaccines. There was no correlation between age or gender and the duration of adverse effects, and some participants reported unusual symptoms like swelling of eyelids and severe allergic reactions. Overall, Pfizer, AstraZeneca, and Sinopharm vaccines were deemed safe, with Sinopharm showing lower prevalence of adverse effects compared to the others.

Summary: In response to the harm inflicted on irregular migrants along their journeys from West Africa to Europe, campaigns have been scaled up to raise awareness about the risks. However, there is limited empirical evidence on the impact and effectiveness of such campaigns. A study conducted in Northern Guinea in 2019 shows that a mobile cinema and community discussion intervention had a positive effect on the perceptions, knowledge, and intentions of potential irregular migrants.

Summary: Phone surveys, particularly through WhatsApp, are increasingly important tools for data collection in developing countries. However, there is limited evidence on the effectiveness of WhatsApp for remote data collection. In a field experiment conducted in Senegal and Guinea, WhatsApp showed lower response rates compared to interactive voice response (IVR), but had higher survey completion rates and lower costs, making it a promising option for data collection in low-income contexts.

Summary: This study examines the impact of Germany's policy of allocating asylum seekers on their language acquisition. The research finds that living in rural areas doesn't have a negative effect on language skills, which is the result of the offset between the negative impact of lower access to formal language courses and the positive impact of more exposure to German speakers.

Summary: The interest in human migration is increasing, but data to measure migration is limited. Digital data sources, such as big data and digital trace data, have emerged as new sources of migration measurement. This paper reviews the strengths and weaknesses of these new data sources, emphasizing the ethical and empirical challenges of migration research. The review aims to assist researchers and policy analysts in navigating this new and complex field.
