BACKGROUND Individuals with comorbid conditions have been disproportionately affected by COVID-19. Since regulatory clinical trials with COVID-19 vaccines excluded those with immunocompromising conditions, few patients with cancer and autoimmune diseases were enrolled. With limited vaccine safety data available, vulnerable populations may have conflicted vaccine attitudes. OBJECTIVE To assess the incidence and reasons for COVID-19 vaccine hesitancy and to assess early vaccine safety. METHODS We conducted a cross-sectional internet-based survey, fielded January 15, 2021 through February 22, 2021, with international participation (74% USA). A random sample of members of Inspire, an online health community of over 2.2 million individuals with comorbid conditions, completed a 55-item online survey. RESULTS 21,943 individuals completed the survey (100% with comorbidities including 27% cancer, 23% autoimmune diseases, 38% chronic lung diseases). 10% declared they would not, 4% stated they probably would not, and 5% were not sure they would agree to vaccination (hesitancy rate 19%). Factors associated with hesitancy included younger age, female gender, black-Pacific-Island-Native American heritage, less formal education, conservative political tendencies, resistance to masks or routine influenza vaccinations, and distrust of media coverage. 5501 (25%) had received at least one COVID-19 vaccine injection, including 29% of US participants. Following the first injection, 69% self-reported local and 40% systemic reactions, which increased following the second injection to 76% and 67%, respectively, with patterns mimicking clinical trials. CONCLUSIONS Nearly one in five individuals with serious comorbid conditions harbor COVID-19 hesitancy. Early safety experiences among those who have been vaccinated should be reassuring.

Background In the United States, underserved communities including Blacks and Latinx are disproportionately affected by COVID-19. This study sought to estimate the prevalence of COVID-19 vaccine hesitancy, describe attitudes related to vaccination, and identify correlates among historically marginalized populations across 9 counties in North Carolina. Methods We conducted a cross-sectional survey distributed at free COVID-19 testing events in underserved rural and urban communities from August 27 –December 15, 2020. Vaccine hesitancy was defined as the response of “no” or “don’t know/not sure” to whether the participant would get the COVID-19 vaccine as soon as it became available. Results The sample comprised 948 participants including 27.7% Whites, 59.6% Blacks, 12.7% Latinx, and 63% female. 32% earned <$20K annually, 60% owned a computer and ~80% had internet access at home. The prevalence of vaccine hesitancy was 68.9% including 62.7%, 74%, and 59.5% among Whites, Blacks, and Latinx, respectively. Between September and December, the largest decline in vaccine hesitancy occurred among Whites (27.5 percentage points), followed by Latinx (17.6) and only 12.0 points among Blacks. 51.2% of respondents reported vaccine safety concerns, 23.7% wanted others to get vaccinated first, and 63.1% would trust health care providers about the COVID-19 vaccine. Factors associated with hesitancy in multivariable logistic regression included being female (OR = 1.90 95%CI [1.36, 2.64]), being Black (OR = 1.68 1.16, 2.45]), calendar month (OR = 0.76 [0.63, 0.92]), safety concerns (OR = 4.28 [3.06, 5.97]), and government distrust (OR = 3.57 [2.26, 5.63]). Conclusions This study engaged the community to directly reach underserved minority populations at highest risk of COVID-19 that permitted assessment of vaccine hesitancy (which was much higher than national estimates), driven in part by distrust, and safety concerns.

Since the start of the COVID-19 outbreak, the race for testing new platforms designed to confer immunity against SARS-CoV-2, has been rampant and unprecedented, leading to conditional emergency authorization of various vaccines. Despite progress on early multidrug therapy for COVID-19 patients, the current mandate is to immunize the world population as quickly as possible. The lack of thorough testing in animals prior to clinical trials, and authorization based on safety data generated during trials that lasted less than 3.5 months, raise questions regarding vaccine safety. The recently identified role of SARS-CoV-2 Spike glycoprotein for inducing endothelial damage characteristic of COVID-19, even in absence of infection, is extremely relevant given that most of the authorized vaccines induce endogenous production of Spike. Given the high rate of occurrence of adverse effects that have been reported to date, as well as the potential for vaccine-driven disease enhancement, Th2-immunopathology, autoimmunity, and immune evasion, there is a need for a better understanding of the benefits and risks of mass vaccination, particularly in groups excluded from clinical trials. Despite calls for caution, the risks of SARS-CoV-2 vaccination have been minimized or ignored by health organizations and government authorities. As for any investigational biomedical program, data safety monitoring boards (DSMB) and event adjudication committees (EAC), should be enacting risk mitigation. If DSMBs and EACs do not do so, we will call for a pause in mass vaccination. If DSMBs and EACs do not exist, then vaccination should be halted immediately, in particular for demographic groups at highest risk of vaccine-associated death or serious adverse effects, during such time as it takes to assemble these boards and commence critical and independent assessments. We urge for pluralistic dialogue in the context of health policies, emphasizing critical questions that require urgent answers, particularly if we wish to avoid a global erosion of public confidence in science and public health.

Acceptance of COVID-19 vaccines needs a health promotion approach to address various social, environmental and personal factors leading to vaccine hesitancy. We assessed the vaccine hesitancy rate and applied social cognitive theory (SCT) to understand COVID-19 vaccine rejection in Qassim, Saudi Arabia. A cross-sectional study was conducted among visitors of 10 randomly selected primary health care centers in Buraidah, Saudi Arabia. Data was collected by a self-administrated questionnaire. The variables were grouped into six constructs of SCT. Logistic regression was used to assess the predictors of vaccine rejection. Out of 486 participants included in the study, 30.5% rejected the vaccine. The most common reason for vaccine rejection was uncertainty about the vaccine’s effectiveness (78%). Among various constructs of SCT, reciprocal determinism (nationality, income and suffering from COVID-19 infection), behavioral capability (knowledge about vaccine safety), self-efficacy (registered for vaccine), and observational learning (getting the vaccine after friends and family members) were significant predictors. Expectation and reinforcement constructs did not show significant association. There was high vaccine rejection in Qassim, KSA. This calls for further improving the mass education strategies. Social cognitive theory can be used to predict vaccine rejection and to develop strategies to increase the utilization of COVID-19 vaccines in Saudi Arabia.

Objectives: Vaccination is the provision of a vaccine to initiate immunity trough stimulating immune system to develop protection from a certain disease. When a sufficiently large proportion of a population has been vaccinated, herd immunity initiated. The effectiveness of vaccination has been widely studied and verified. Although the harsh vaccine safety systems, some parents remain minded regarding the safety of the childhood vaccines and immunization schedule. These hesitations pushed some parents to not allow their children to receive some or all the scheduled vaccines.  The aim of the study is to assess the general population awareness regarding vaccines and to detect prevalence of vaccine hesitancy in Aseer region, southern of Saudi Arabia. Methods: A descriptive cross-sectional approach was used targeting all parents in Aseer region. Data were collected using structured questionnaire which developed by the researchers after intensive literature review and expert’s consultation. The questionnaire data included parents’ socio-demographic data, parents’ awareness regarding child vaccines safety and efficacy, parents’ attitude and adherence to children vaccination and hesitancy towards vaccines. Results: The survey included 796 participants whose ages ranged from 18 to 55 years old. Two thirds (63.4%) of the participants were females. Regarding vaccination adherence and hesitancy among participants, more than three quarters were completely adherent to the child vaccination schedule and only 3.9% were non adherent. As for participants awareness regarding child vaccination safety and efficacy, 89.3% of the respondents agreed on that vaccination keep child healthy, 84.2% reported that child vaccine is safe and effective, 83.4% said that all Saudi scheduled vaccines are effective. Conclusion: In conclusion, the study revealed that vaccine hesitancy among participants was not low and should be considered irrespective of their high awareness level. The recorded antivaccine action was mostly related to vaccines safety not efficacy. Keywords: Vaccine hesitancy, antivaccine movement, parents, awareness, adherence

Abstract Background The coronavirus disease 2019 (COVID-19) has spread worldwide, and the vaccine remains the ultimate cornerstone to overcoming its long-term impact. Vaccine hesitancy might obstruct the effort to achieve herd immunity and eradicate the virus. We assessed Saudi Arabian individuals’ willingness, beliefs, and barriers regarding the COVID-19 vaccine and their adherence to preventive measures during and after the pandemic. Methods A self-administered electronic validated questionnaire was distributed among the five major regions in Saudi Arabia between November and December 2020. The questionnaire addressed the sociodemographic data, beliefs, potential barriers, parents’ acceptance of COVID-19 vaccination for their children, and adherence to protective measures during and after the pandemic. Results Of 8,056 participants, 4,218 (52.4%) of a non-representative sample were willing to be vaccinated against COVID-19. Being a young adult, male, having less than a high school degree, being a smoker, having a chronic disease, and having a history of seasonal influenza vaccine uptake were positive predictors of COVID-19 vaccine acceptance. Hesitant participants reported concerns about vaccine side effects and safety as the main barriers to accepting the COVID-19 vaccine. Some refusers (26.1%) declared that they would reconsider vaccination only if the safety and effectiveness of the vaccine were reported by more studies. Conclusions Our study revealed a promising willingness to accept the vaccine among the population, with positive beliefs and attitudes toward COVID-19 vaccination. However, a considerable proportion of the population was reluctant to accept the vaccine. Thus, publicly providing information about vaccine safety and implementing health education programs is crucial for increasing the public’s confidence in the vaccine.

Vaccine hesitancy has surfaced globally within the last few decades, and the fears and misconceptions of people about vaccine safety and effectiveness have been identified as key factors for their under-utilization. The familiarity, attitudes, and religious beliefs of the public and of future healthcare practitioners regarding vaccination are extensive areas needing exploration. The present exploratory cross-sectional study was designed, planned and carried out on students enrolled in health science and non-health science courses in one of the public universities of Malaysia. A research instrument that had been formulated, validated and subjected to reliability testing was used to collect the data, which were analyzed using descriptive and inferential statistics. A response rate of 80.8% (n = 202) was obtained: the majority were female (n = 161, 79.7%), and had been vaccinated before (n = 190, 97.5%), while a mere 2% did not support vaccination for reasons pertaining to safety issues. The vaccine familiarity score was 10.79 ± 1.4, which significantly differed among the study disciplines (p < 0.001). The mean of the total attitude score was 14.95 ± 1.5, with no significant difference among demographics being noted. The mean of the total religious beliefs score was 24.29 ± 2.8 and significantly differed based on gender (p = 0.040) and study disciplines (p < 0.001). The current findings showed that the participants were familiar with vaccines and had generally positive attitudes and positive religious beliefs toward vaccination; thus, one can expect that their inclusion in immunization campaigns will generate positive outcomes of the immunization program. Although the current research reported few knowledge gaps, these may be handled with the introduction of a specialized immunization course at an undergraduate level.

Background As the COVID-19 pandemic continues to spread across the globe, the search for an effective medication to treat the symptoms of COVID-19 continues as well. It would be desirable to identify a medication that is already in use for another condition and whose side effect profile and safety data are already known and approved. Objective The objective of this study was to evaluate the effect of different medications on typical COVID-19 symptoms by using data from an online surveillance survey. Methods Between early April and late-July 2020, a total of 3654 individuals in Lower Saxony, Germany, participated in an online symptom-tracking survey conducted through the app covid-nein-danke.de. The questionnaire comprised items on typical COVID-19 symptoms, age range, gender, employment in patient-facing healthcare, housing status, postal code, previous illnesses, permanent medication, vaccination status, results of reverse transcription polymerase chain reaction (RT-PCR) and antibody tests for COVID-19 diagnosis, and consequent COVID-19 treatment if applicable. Odds ratio estimates with corresponding 95% CIs were computed for each medication and symptom by using logistic regression models. Results Data analysis suggested a statistically significant inverse relationship between typical COVID-19 symptoms self-reported by the participants and self-reported statin therapy and, to a lesser extent, antihypertensive therapy. When COVID-19 diagnosis was based on restrictive symptom criteria (ie, presence of 4 out of 7 symptoms) or a positive RT-PCR test, a statistically significant association was found solely for statins (odds ratio 0.28, 95% CI 0.1-0.78). Conclusions Individuals taking statin medication are more likely to have asymptomatic COVID-19, in which case they may be at an increased risk of transmitting the disease unknowingly. We suggest that the results of this study be incorporated into symptoms-based surveillance and decision-making protocols in regard to COVID-19 management. Whether statin therapy has a beneficial effect in combating COVID-19 cannot be deduced based on our findings and should be investigated by further study.
