Summary: The fear of unknown long-term adverse effects and concerns about the impact on reproductive health and fertility are major reasons for vaccine hesitancy among unvaccinated adults. Providing more information and research on the COVID-19 vaccines is seen as the most effective way to encourage vaccine uptake.

Summary: This study assessed Persian tweets to analyze Iranian people's views toward COVID-19 vaccination and compare their views toward homegrown and imported vaccines. The results showed a subtle difference in positive sentiments between the two types of vaccines, with the imported vaccines having a dominant positive polarity. Negative sentiments toward both homegrown and imported vaccines appeared to increase in certain months. No significant differences were observed in the overall percentage of positive and negative opinions toward vaccination among Iranian people.

Summary: This study analyzed tweets on Twitter mentioning COVID-19 vaccination in the Thai language and found that the vaccination actions or promotional activities by public figures significantly increased positive sentiment among the public. This suggests that public figures and medical professionals can play a positive role in improving public perceptions of vaccination and should be encouraged to actively support vaccination campaigns.

Summary: Medical students generally have positive attitudes towards COVID-19 vaccines, but some are hesitant to participate in vaccine trials or get vaccinated immediately. Students willing to get vaccinated right away are more likely to trust public health experts and have fewer concerns about side effects, while concerns about serious side effects are associated with lower intent to participate in vaccine trials.

Summary: Identifying and understanding COVID-19 vaccine hesitancy within distinct populations may aid future public health messaging. Using nationally representative data from the general adult populations of Ireland and the UK, the study found differences in vaccine hesitancy/resistance between the two countries but similarities in psychological constructs among resistant respondents. Vaccine-resistant individuals in both populations were less likely to obtain information from traditional and authoritative sources and had similar levels of mistrust in these sources compared to vaccine-accepting individuals.

Summary: Vaccine hesitancy is a challenge for achieving population immunity. A study among medical students in Egypt found that most students recognized the importance of the COVID-19 vaccine but had hesitancy due to concerns about adverse effects and ineffectiveness. Efforts are needed to reduce hesitancy and raise awareness about vaccinations to improve acceptance of COVID-19 vaccines.

Summary: COVID-19 vaccine acceptance rates are generally high worldwide, but low rates are reported in the Middle East, Russia, Africa, and certain European countries. This could pose a significant challenge in global efforts to control the pandemic. More studies are recommended to address COVID-19 vaccine hesitancy in different regions.

Summary: This study aimed to assess the factors associated with COVID-19 vaccine hesitancy in Portugal and found that factors such as being younger, loss of income, intention to flu vaccine and COVID-19 vaccine refusal, confidence in health service response, perception of government measures, and inconsistent information were linked to delay or refusal of COVID-19 vaccines. It is crucial to build confidence in the COVID-19 vaccine as its perceived safety and efficacy were strongly associated with intention to take the vaccine.

Summary: This review summarizes rates of COVID-19 vaccine hesitancy and its determinants in high-income countries or regions, indicating that factors such as younger age, female gender, lower education level, and concerns about vaccine safety/efficacy are associated with increased vaccine hesitancy. Policy makers can use these findings to formulate health policies related to COVID-19 vaccination.

Summary: One year into the COVID-19 pandemic and one of the longest recorded lockdowns in the world, the Philippines received its first delivery of COVID-19 vaccines on 1 March 2021 through WHO's COVAX initiative. A month into inoculation of all frontline health professionals and other priority groups, the authors of this study gathered data on the sentiment of Filipinos regarding the Philippine government's efforts using the social networking site Twitter. Natural language processing techniques were applied to understand the general sentiment, which can help the government in analyzing their response. The sentiments were annotated and trained using the Naive Bayes model to classify English and Filipino language tweets into positive, neutral, and negative polarities through the RapidMiner data science software. The results yielded an 81.77% accuracy, which outweighs the accuracy of recent sentiment analysis studies using Twitter data from the Philippines.
