Project description:BackgroundVaccination may be critical to curtailing the spread of the SARS-CoV-2 virus responsible for the COVID-19 pandemic, but herd immunity can only be realized with high vaccination coverage. There is a need to identify empirically supported strategies to increase uptake, especially among young adults as this subpopulation has shown relatively poor adherence to physical distancing guidelines. Social norms - estimates of peers' behavior and attitudes - are robust predictors of health behaviors and norms-based intervention strategies may increase COVID vaccine uptake, once available. This study examined the extent that vaccination intentions and attitudes were associated with estimated social norms as an initial proof-of-concept test.MethodIn November of 2020, 647 undergraduate students (46.21% response rate) completed online surveys in which they reported intentions to get COVID and influenza vaccines, perceived importance of these vaccines for young adults, and estimated social norms regarding peers' vaccination behaviors and attitudes.ResultsStudents reported significantly greater intentions to get a COVID vaccine (91.64%) than an influenza vaccine (76.04%), and perceived COVID vaccination as significantly more important than influenza vaccination. The sample generally held strong intentions to receive a COVID vaccine and thought that doing so was of high importance, but participants, on average, perceived that other young adults would be less likely to be vaccinated and would not think vaccination was as important. Multiple regression models indicated that estimated social norms were positively associated with participants' own intentions and perceived importance of getting a COVID vaccine.ConclusionsThese significant associations highlight the potential value in developing and testing norms-based intervention strategies, such as personalized normative feedback, to improve uptake of forthcoming COVID vaccines among young adults.

Project description:High vaccination rates are integral to reducing infection and severity rates of COVID-19 infections within a community. We examine the role of social expectations in COVID-19 vaccination take-ups and its interaction with potential government actions in Malaysia. We find that individuals' expectations of others in their social groups towards vaccination predicts those individuals' vaccination registrations. Using a vignette experiment, we examine the extent of normative expectations in normalizing pro-vaccination behavior beyond an individual's reference group. We find that unless moderated by a high level of public trust, individuals prefer punitive policies as a way to increase vaccination rates in their communities.

Project description:Among US adults, the highest rates of hesitancy to receive the COVID-19 vaccine are among young adults aged 18 to 25. Vaccine hesitancy is particularly concerning among young adults in college, where social interactions on densely populated campuses can lead to substantial community spread. Given that many colleges have opted not to mandate vaccines, identification of modifiable predictors of vaccine hesitancy - such as perceived social norms - is key to informing interventions to promote vaccine uptake. To address this need, we examined predictors of and explicit reasons for vaccine hesitancy among 989 students aged 18 to 25 recruited from four geographically diverse US universities in the spring of 2021. At the time of the survey, 57.3% had been vaccinated, 13.7% intended to be vaccinated as soon as possible, and 29.0% were vaccine hesitant. Common reasons for hesitancy were wanting to see how it affected others first (75.2%), not believing it was necessary (30.0%), and other reasons (17.4%), which were examined via content analysis and revealed prominent safety concerns. Despite these varied explicit reasons, logistic regressions revealed that, when controlling for demographics and pandemic-related experiences, perceived descriptive and injunctive social norms for vaccine uptake were each significant predictors of vaccine hesitancy (ORs = 0.35 and 0.78, respectively). When both norms were entered into the same model, only perceived descriptive norms uniquely predicted vaccine hesitancy (OR = 0.37; 95% CI: 0.29 - 0.46). Findings suggest perceived social norms are strongly associated with vaccine-related behavior among young adult college students. Correcting normative misperceptions may be a promising approach to increase vaccine uptake and slow the spread of COVID-19 among young adults.

Project description:IntroductionThe COVID-19 outbreak devastated the fragmented health system in Syria, a war-torn country, and exaggerated the demands for humanitarian assistance. COVID-19 vaccination was rolled out in Northwest Syria, an area out of government control, in May 2021. However, vaccine acceptance rates are still minimal, which is reflected in the meager percentage of vaccinated people. The study aims to investigate the effectiveness of the humanitarian actors' plans to address the COVID-19 vaccine hesitancy and conclude practical strategies for boosting vaccine uptake in Northwest Syria.Methods and materialsTwo questionnaires were developed to collect data from humanitarian organizations involved in the COVID-19 vaccination campaign and people from northwest Syria. Data analysis was performed using SPSS 22 data analysis program.ResultsAccording to the findings, 55.5% of people refused the COVID-19 vaccine. The results showed a knowledge gap and lack of evidence regarding humanitarian actors' strategies to address the vaccine's low uptake. Besides, it was found that doctors and medical workers were reliable sources of information about the vaccine. However, they were not systematically engaged in community mobilization and risk communication to promote people's perspectives on the vaccine.ConclusionRisk communication and community engagement programs were not significantly associated with increasing the COVID-19 acceptance rate. Humanitarian actors must reconsider their strategies to address vaccine hesitancy in Northwest Syria. These strategies should engage medical professionals through dialogue sessions on the realities of the pandemic and vaccine development mechanism based on a compelling and evidence-based approach.

Project description:COVID-19 vaccines have reduced infections and hospitalizations across the globe, yet resistance to vaccination remains strong. This paper investigates the role of cable television news in vaccine hesitancy and associated local vaccination rates in the United States. We find that, in the earlier stages of the vaccine roll-out (starting May 2021), higher local viewership of Fox News Channel has been associated with lower local vaccination rates. We can verify that this association is causal using exogenous geographical variation in the channel lineup. The effect is driven by younger individuals (under 65 years of age), for whom COVID-19 has a low mortality risk. Consistent with changes in beliefs about the effectiveness of the vaccine as a mechanism, we find that Fox News increased reported vaccine hesitancy in local survey responses. We can rule out that the effect is due to differences in partisanship, to local health policies, or to local COVID-19 infections or death rates. The other two major television networks, CNN and MSNBC, have no effect. That, in turn, indicates that more differentiated characteristics, like the networks' messaging or tendency for controversy, matter and that the effect of Fox News on COVID-19 vaccine uptake is not due to the general consumption of cable news. We also show that there is no historical effect of Fox News on flu vaccination rates, suggesting that the effect is COVID-19-specific and not driven by general skepticism toward vaccines.

Project description:In the last two years, the coronavirus disease 19 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a scientific and social challenge worldwide. Vaccines have been the most effective intervention for reducing virus transmission and disease severity. However, virus genetic variants are still circulating among vaccinated individuals with different symptomatology disease cases. Understanding the protective or disease associated mechanisms in vaccinated individuals is relevant to advance in vaccine development and implementation. To address this objective, serum protein profiles were characterized by quantitative proteomics and data analysis algorithms in four cohorts of vaccinated individuals uninfected and SARS-CoV-2 infected with asymptomatic, nonsevere and severe disease symptomatology. The results showed that immunoglobulins were the most overrepresented proteins in infected cohorts when compared to PCR-negative individuals. The immunoglobulin profile varied between different infected cohorts and correlated with protective or disease associated capacity. Overrepresented immunoglobulins in PCR-positive individuals correlated with protective response against SARS-CoV-2, other viruses, and thrombosis in asymptomatic cases. In nonsevere cases, correlates of protection against SARS-CoV-2 and HBV together with risk of myasthenia gravis and allergy and autoantibodies were observed. Patients with severe symptoms presented risk for allergy, chronic idiopathic thrombocytopenic purpura, and autoantibodies. The analysis of underrepresented immunoglobulins in PCR-positive compared to PCR-negative individuals identified vaccine-induced protective epitopes in various coronavirus proteins including the Spike receptor-binding domain RBD. Non-immunoglobulin proteins were associated with COVID-19 symptoms and biological processes. These results evidence host-associated differences in response to vaccination and the possibility of improving vaccine efficacy against SARS-CoV-2.

Project description:This article describes patterns of compliance with social distancing measures among the Spanish population during the coronavirus disease-2019 (COVID-19) pandemic. It identifies several factors associated with higher or lower compliance with recommended measures of social distancing. This research is part of a 67-country study, titled the International COVID-19 study on Social & Moral Psychology, in which we use a Spanish dataset. Participants were residents in Spain aged 18 or above. The sample comprises 1,090 respondents, weighted to be representative of the Spanish population. Frequencies, correlations, bivariate analysis, and six models based on hierarchical multiple regressions were applied. The main finding is that most Spaniards are compliant with established guidelines of social distance during the pandemic (State of Alarm, before May 2020). Variables associated more with lower levels of compliance with these standards were explored. Six hierarchical multiple regression models found that compliance with social distance measures has a multifactorial explanation (R 2 between 20.4 and 49.1%). Sociodemographic factors, personal hygiene patterns, and the interaction between personal hygiene patterns and the support for political measures related to the coronavirus brought significant effects on the regression models. Less compliance was also associated with beliefs in some specific conspiracy theories with regard to COVID-19 or general conspiracy mentality (Conspiracy Mentality Questionnaire, CMQ), consumption patterns of traditional mass media (television, paper newspapers, magazines, and radio) and modern means to get informed (online digital newspapers, blogs, and social networks), political ideology, vote, trust in institutions, and political identification. Among the future lines of action in preventing the possible outbreak of the virus, we suggest measures to reinforce trust in official information, mainly linked to reducing the influence of disinformation and conspiracy theories parallel to the pandemic.

Project description:While effective preventive measures against COVID-19 are now widely known, many individuals fail to adopt them. This article provides experimental evidence about one potentially important driver of compliance with social distancing: social norms. We asked each of 23,000 survey respondents in Mexico to predict how a fictional person would behave when faced with the choice about whether or not to attend a friend's birthday gathering. Every respondent was randomly assigned to one of four social norms conditions. Expecting that other people would attend the gathering and/or believing that other people approved of attending the gathering both increased the predicted probability that the fictional character would attend the gathering by 25%, in comparison with a scenario where other people were not expected to attend nor to approve of attending. Our results speak to the potential effects of communication campaigns and media coverage of compliance with, and normative views about, COVID-19 preventive measures. They also suggest that policies aimed at modifying social norms or making existing ones salient could impact compliance.

Project description:The uptake of the COVID-19 vaccine will determine the trajectory for improved population health and economic recovery from the COVID-19 pandemic. Identifying factors associated with vaccine acceptance is imperative as public health officials strategize to improve uptake. In this study, we identified predictors of vaccine willingness and acceptance using univariate logistic regression to model predictors and calculate odds ratios. Participants (N = 946) who reported greater vaccine willingness were male, older, and had a higher level of education and income. Behaviors indicative of reducing the spread of COVID-19 (e.g., testing) and perceived risk of COVID-19 infection were associated with vaccine willingness, as were participants who believed they were "highly likely" to be infected (by a factor of 8). Education tailored to demographic groups with low vaccine uptake should focus on the high degree of communicability associated with COVID-19. Implementing mobile healthcare screenings could remove barriers to healthcare, thereby improving health equity.

Project description:The SARS-CoV-2 Delta (B.1.617.2) variant is capable of infecting vaccinated persons. An open question remains as to whether deficiencies in specific vaccine-elicited immune responses result in susceptibility to vaccine breakthrough infection. We investigated 55 vaccine breakthrough infection cases (mostly Delta) in Singapore, comparing them against 86 vaccinated close contacts who did not contract infection. Vaccine breakthrough cases showed lower memory B cell frequencies against SARS-CoV-2 receptor binding domain (RBD). Compared to plasma antibodies, antibodies secreted by memory B cells retained a higher fraction of neutralizing properties against the Delta variant. Inflammatory cytokines including IL-1β and TNF were lower in vaccine breakthrough infections than primary infection of similar disease severity, underscoring the usefulness of vaccination in preventing inflammation. This report highlights the importance of memory B cells against vaccine breakthrough, and suggests that lower memory B cell levels may be a correlate of risk for Delta vaccine breakthrough infection.
