Change of Willingness to Accept COVID-19 Vaccine and Reasons of Vaccine Hesitancy of Working People at Different Waves of Local Epidemic in Hong Kong, China: Repeated Cross-Sectional Surveys

Vaccine hesitancy is among the major threats to the effectiveness of vaccination programmes. This study aimed to report the trend in response to willingness to accept the COVID-19 vaccine between two waves of the local epidemic and examine differences among occupations. Two cross-sectional surveys were conducted online during the first wave (February) and third wave (August to September) of the local epidemic in 2020. Acceptance of the COVID-19 vaccine was measured along with personal protection behaviours and occupations. A total of 2047 participants provided valid responses. The willingness to accept the COVID-19 vaccine among the participants was lower in the third wave (34.8%) than the first wave (44.2%). There were more concerns over vaccine safety in the third wave. Clerical/service/sales workers were less likely to accept the vaccine (adjusted odds ratio: 0.62, 95% confidence interval: 0.43–0.91). A high-level compliance of facemask wearing was found, and more people maintained social distancing and used alcohol hand rub in the third wave. Decreasing willingness to accept the COVID-19 vaccine may be associated with increasing concerns about vaccine safety and growing compliance of personal protection behaviours. The rush of vaccine development with higher risks of safety issues may jeopardize the public’s trust and lower uptake rates. Education and favourable policy should be provided to the general working population for the vaccination, especially for those who are not professional and are frequently exposed to crowds.

Abstract Background: In Yemen the epidemiology of COVID19 is uncertain. Yemen received the first batch of AstraZeneca vaccine in April 2021 and the vaccine campaign starts officially on 20 April 2021 with limited utilization. Media play a negative role about AstraZeneca vaccine safety and efficacy.Objectives: to investigate the acceptance of People and health workers in Mukalla city in Hadharmout (at eastern Yemen) toward the COVID-19 vaccine.Methodology: This is a cross-sectional study to collect data from a convenience sample of health workers and other people during the first week of April 2021. Results: A total of 321 persons agree to participate in the study. Only 9% of the participants and 22% of health workers have knowledge about the COVID19 vaccine, only 15% of people and 26% of health workers agree to get the vaccine while 241 participants (75%) hesitated to get the vaccine. The most reasons for vaccine hesitancy were: the vaccine were arrived to Yemen of bad quality (69%), while 48% of hesitated participants said that the vaccine is unsafe, other reasons for unacceptance the vaccine are: regional believes (38%), other countries stop the vaccine (37%) while 16% of refused participants said that the reason is that the virus is subject to mutation so no need to vaccinate. Conclusions: Lack of knowledge about COVID-19 vaccine and high level of vaccine hesitancy were reported, the most frequent reasons for not accepted the vaccine are: bad quality of the vaccine and doubts about vaccine safety.

Abstract Background The unprecedented rapid development of COVID-19 vaccines has faced SARS-CoV- (COVID-19) vaccine hesitancy, which is partially fueled by the misinformation and conspiracy theories propagated by anti-vaccine groups on social media. Research is needed to better understand the early COVID-19 anti-vaccine activities on social media. Methods This study chronicles the social media posts concerning COVID-19 and COVID-19 vaccines by leading anti-vaccine groups (Dr Tenpenny on Vaccines, the National Vaccine Information Center [NVIC] the Vaccination Information Network [VINE]) and Vaccine Machine in the early months of the COVID-19 pandemic (February–May 2020). Results Analysis of 2060 Facebook posts showed that anti-vaccine groups were discussing COVID-19 in the first week of February 2020 and were specifically discussing COVID-19 vaccines by mid-February 2020. COVID-19 posts by NVIC were more widely disseminated and showed greater influence than non-COVID-19 posts. Early COVID-19 posts concerned mistrust of vaccine safety and conspiracy theories. Conclusion Major anti-vaccine groups were sowing seeds of doubt on Facebook weeks before the US government launched its vaccine development program ‘Operation Warp Speed’. Early anti-vaccine misinformation campaigns outpaced public health messaging and hampered the rollout of COVID-19 vaccines.

The COVID-19 pandemic has impacted the mental health of people worldwide. An increase in perceived stress can lead to unhealthy behaviors such as increased food consumption. The aim of this study was to find the level of perceived stress and its relationship with increased food consumption during the “third wave” of the COVID-19 pandemic in Spain. This was a cross-sectional study that employed anonline self-reported frequency of consumption questionnaire and the Perceived Stress Scale-10. A total of 637 subjects participated and 83.6% of respondents had moderate or high stress—more prevalent in the female and young respondents. Moreover, 36.1% of respondents reported that they had increased the frequency of consumption of some foods, mainly nuts, snacks, and jellybeans, along with coffee, tea, cocoa, and soft drinks. Eating between meals was more pronounced in those with high stress (65.1%) than in those with moderate stress (40.4%) and low stress (20.2%). Furthermore, the respondents with high stress reported greater weight gain. Thus, the results show that the level of perceived stress during the ‘third wave’ of this pandemic increased food consumption.

Background: While the COVID-19 pandemic has spread globally, health systems are overwhelmed by both direct and indirect mortality from other treatable conditions. COVID-19 vaccination was crucial to preventing and eliminating the disease, so vaccine development for COVID-19 was fast-tracked worldwide. Despite the fact that vaccination is commonly recognized as the most effective approach, according to the World Health Organization (WHO), vaccine hesitancy is a global health issue. Methods: We conducted a cross-sectional online survey of nurses in four different regions in Italy between 20 and 28 December 2020 to obtain data on the acceptance of the upcoming COVID-19 vaccination in order to plan specific interventions to increase the rate of vaccine coverage. Results: A total of 531 out of the 5000 nurses invited completed the online questionnaire. Most of the nurses enrolled in the study (73.4%) were female. Among the nurses, 91.5% intended to accept vaccination, whereas 2.3% were opposed and 6.2% were undecided. Female sex and confidence in vaccine efficacy represent the main predictors of vaccine intention among the study population using a logistic regression model, while other factors including vaccine safety concerns (side effects) were non-significant. Conclusions: Despite the availability of a safe and effective vaccine, intention to be vaccinated was suboptimal among nurses in our sample. We also found a significant number of people undecided as to whether to accept the vaccine. Contrary to expectations, concerns about the safety of the vaccine were not found to affect the acceptance rate; nurses’ perception of vaccine efficacy and female sex were the main influencing factors on attitudes toward vaccination in our sample. Since the success of the COVID-19 immunization plan depends on the uptake rate, these findings are of great interest for public health policies. Interventions aimed at increasing employee awareness of vaccination efficacy should be promoted among nurses in order to increase the number of vaccinated people.

SARS-CoV-2 coronavirus emerged in the world at the end of 2019. The introduction of a number of restrictions had a significant effect on numerous aspects of human life with particular influence being exerted on pregnant women and their sense of security. The study aimed to assess the level of anxiety and its main determinants in women in the third trimester of pregnancy during the coronavirus pandemic. The study technique included the present purposely designed questionnaire, Labor Anxiety Questionnaire (KLPII), and the State-Trait Anxiety Inventory (STAI). The study was conducted in a group of 315 women in the third trimester of pregnancy. A total of 258 women (81.9%) completed the questionnaire in May 2020, and 57 of them (18.1%) completed it in October 2020. The overall analysis of the Labor Anxiety Questionnaire and the STAI inventory revealed a high level of anxiety, particularly situational anxiety, in pregnant women during the SARS-CoV-2 pandemic. The age and financial status of the women were the factors which contributed to the intensification of tokophobia. Women interviewed in October 2020 were characterized by higher tokophobia levels compared to the respondents included in May 2020. It seems justified to in-crease the vigilance in the diagnostics of possible mental disorders in the perinatal period during pandemic.

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.

148 Background: The World Health Organization cited vaccine hesitancy as one of 2019’s top ten threats to global health, a threat that has been further exacerbated by COVID-19 pandemic. Existing COVID-19 vaccine hesitancy research focuses on the general population, but less is known about the specific concerns of medically vulnerable populations, including individuals with cancer. Methods: This cross-sectional analysis used data that assessed likelihood of COVID-19 vaccination (likely vs unlikely/unsure) among past or current patients with cancer from a nationwide survey administered in December 2020 by the Patient Advocate Foundation (PAF), a non-profit organization that provides case management and financial aid to patients diagnosed with a chronic illness. Inclusion criteria included previous or current cancer treatment, aged ≥ 19, and a valid e-mail address. Age, sex, race/ethnicity, and urban/rural residence were abstracted from the PAF database. Respondents self-reported education level, employment status, trust in media regarding COVID-19 pandemic, and media viewership on COVID-19 vaccine development. The Group-Based Medical Mistrust Scale assessed respondents’ level of mistrust in medical providers based on ethnicity. Likelihood of COVID-19 vaccine acceptance was evaluated using risk ratios (RR) and 95% confidence intervals (CI) from modified Poisson regression models with robust error variance. All variables were included in our model. Results: Of 429 respondents, 48% were unlikely/unsure about accepting the COVID-19 vaccine, primarily due to concerns about vaccine safety (32%) and worry about health conditions (12%). When compared to those likely to accept COVID-19 vaccine, respondents who were unlikely/unsure were more often Black, Indigenous, or People of Color (40% vs. 23%), aged 36-55 (40% vs. 29%), and female (80% vs. 65%). In adjusted analysis, Black respondents were 55% less likely to accept a COVID-19 vaccine, when compared to White respondents (RR 0.55; 95% CI 0.4-0.8). When compared to those who did not follow the media regarding COVID-19 vaccine development, those who followed the media very closely were 4.5 times more likely to accept a COVID-19 vaccine (RR 4.5; 95% CI 1.6-13.2). Respondents who reported below average trust in the media were 60% less likely to accept a COVID-19 vaccine (RR 0.6; 95% CI 0.5-0.8), compared to those who reported above average trust in the media. Conclusions: Despite being at high risk of COVID-19 morbidity and mortality, a substantial proportion of under-resourced individuals with cancer were unlikely/unsure about vaccination, exposing a significant disconnect between risk of severe disease and vaccine acceptance. Our analysis also reveals a need to assess for and debunk misinformation to increase vaccine enthusiasm among medically vulnerable populations.

Abstract Background The COVID-19 pandemic has brought vaccination to the forefront of discourse on public health. The rapid speed of COVID-19 vaccine development, utilization of novel technology, and an atmosphere of politicized misinformation have created a perfect storm for vaccine hesitancy. As early adopters of vaccination, HCWs set an example for the general population; as trusted sources of medical information, they educate and inform. However, comparatively little work has investigated HCWs' attitudes toward vaccination and how those attitudes drive their recommendation behavior. Methods We surveyed hospital employees about their personal reasons for hesitancy and beliefs about patient hesitancies and randomly assigned them to see one of three messages aimed at increasing vaccine confidence. Message themes included an appeal to return to normal life (Normalcy), a risk comparison between vaccinating or not (SDT), and an explanation of the speed of safe and effective vaccine development (Process). Results Of the 674 NC hospital employees who completed our survey in February 2021, 98% had been offered the COVID-19 vaccine, and 80% had already accepted. For the 20% who had not received the vaccine, the top reasons for hesitancy involved the speed of development and testing, and concerns of vaccine safety and effectiveness. We also found differences in susceptibility to misinformation and vaccine hesitancy across political affiliation, which was higher in Republicans compared to Democrats. HCWs were generally very comfortable recommending the COVID-19 vaccine to patients and supported the idea of sharing the message they read. Although the risk comparison message was most trusted personally, the process message was rated as both the most helpful to patients and the most likely to be shared with them (see Figure 1). This suggests that what is most appealing on a personal level is not necessarily what a HCW would recommend to their patients. Rating of personal opinions of the passages. On a scale from 1 to 7 with 1 = Strongly Disagree and 7 = Strongly Agree. This chart shows the average message ratings across the board when answering whether they thought the passages were understandable, helpful, correct, believable, and trustworthy. (Error bars are 95% CI) There was no significant difference across the messages. The Process message is seen as most helpful and is most likely to be shared with patient than the other messages On left, the average answer on a scale from 1 to 5 for “Do you think the passage you just read would help your patients feel more comfortable about getting the vaccine?” and on right, the average answer for “Would you share this passage with your patients?” Conclusion HCWs' high uptake and minimal hesitancy in recommending the COVID-19 vaccine is encouraging and merits further exploration for how to increase confidence in HCW who are hesitant to discuss and recommend vaccines to patients, as several highlighted the importance of respecting patient autonomy.

Vaccination Hesitancy

Aims of the study: Vaccination is regarded as the most promising response to the COVID-19 pandemic. We assessed opinions towards COVID-19 vaccination, willingness to be vaccinated, and reasons for vaccination hesitancy among health care workers (HCWs). Methods: We conducted a cross-sectional, web-based survey among 3,793 HCWs in December 2020 in the Canton of Solothurn, Switzerland, before the start of the national COVID-19 vaccination campaign. Results: Median age was 43 years (interquartile range [IQR] 31-53), 2,841 were female (74.9%). 1,511 HCWs (39.8%) reported willingness to accept vaccination, while 1,114 (29.4%) were unsure, and 1,168 (30.8%) would decline vaccination. Among medical doctors, 76.1% were willing, while only 27.8% of nurses expressed willingness. Among 1,168 HCWs who would decline vaccination, 1,073 (91.9%) expressed concerns about vaccine safety and side effects. The willingness of HCWs to be vaccinated was associated with older age (adjusted odds ratio [aOR] 1.97, 95%Cl 1.71-2.27) and having been vaccinated for influenza this year (aOR 2.70, 95%Cl 2.20-3.31). HCWs who reported a lack of confidence in government were less likely to be willing to be vaccinated (aOR 0.58, 95%Cl 0.40-0.84), and women were less willing to be vaccinated than men (OR 0.33 (0.28-0.38). Conclusion: Less than half of HCWs reported willingness to be vaccinated before the campaign start, but proportions varied greatly depending on the profession and workplace. Strategies with clear and objective messages that particularly address the concerns of HCWs are needed if their willingness to be vaccinated is to be increased.

ABSTRACTObjectivesTo describe time trends in social contacts of individuals according to comorbidity and vaccination status before and during the first three waves of the COVID-19 pandemic in Quebec, Canada.DesignRepeated cross-sectional population-based surveys.SettingGeneral population.ParticipantsNon-institutionalized adults from Quebec, Canada, recruited by random digit dialling before (2018/2019) and during the pandemic (April 2020 to July 2021). A total of 1441 and 5185 participants with and without comorbidities, respectively, were included in the analyses.Main outcome measuresNumber of social contacts (two-way conversation at a distance ≤2 meters or a physical contact, irrespective of masking) documented in a self-administered web-based questionnaire. We compared the mean number of contacts according to the comorbidity status of participants (pre-existing medical conditions with symptoms/medication in the past 12 months) and 1-dose vaccination status during the third wave. All analyses were performed using weighted generalized linear models with a Poisson distribution and robust variance.ResultsContacts significantly decreased from a mean of 6.1 (95% confidence interval 4.9 to 7.3) before the pandemic to 3.2 (2.5 to 3.9) during the first wave among individuals with comorbidities, and from 8.1 (7.3 to 9.0) to 2.7 (2.2 to 3.2) among individuals without comorbidities. Individuals with comorbidities maintained fewer contacts than those without comorbidities in the second wave, with a significant difference before the Christmas 2020/2021 holidays (2.9 (2.5 to 3.2) v 3.9 (3.5 to 4.3); P<0.001). During the third wave, contacts were similar for individuals with (4.1, 3.4 to 4.7) and without comorbidities (4.5, 4.1 to 4.9; P=0.27). This could be partly explained by individuals with comorbidities vaccinated with their first dose who increased their contacts to the level of those without comorbidities.ConclusionsThe lower level of contacts maintained by individuals with comorbidities could have influenced the burden of hospitalisations and deaths of the second wave in Quebec. It will be important to closely monitor COVID-19-related outcomes and social contacts by comorbidity and vaccination status to inform targeted or population-based interventions.
