Filter by:Vaccine hesitancy is defined by World Health Organization(WHO) "Vaccine Hesitancy Working Group" as a delay in acceptance or refusal of vaccines despite availability of vaccination services(MacDonald,2015). WHO listed "vaccine hesitancy" as one of the ten global health threats that require immediate solution in 2019(WHO, 2019). It was found out that the primary causes of vaccine hesitancy are the risk-benefit ratio concerns, including "concerns about the safety of vaccines" or "their potential side-effects", and secondary causes are the lack of information and awareness about vaccines and their importance and religious, cultural, social gender and socioeconomic perceptions of vaccination(Lark et al., 2018).It is estimated in social studies that the prevalence of vaccine hesitancy is about 25-70% in the top-ranking France, 15% in Switzerland and 19% in Canada(Ward et al.,2019; Shen and Dubey,2019). In the case of pregnant women, on the other hand, childhood vaccine hesitancy has been detected to vary between 6% and 12%(Mohd et al.,2017; Corben and Leask,2018). There is a critical increase in the number of unvaccinated children in Turkey(Turkish Medical Association, 2018).Based on the data from Ministry of Health, number of families that refused to get their children vaccinated rose from 183 in 2011 to 12000 in 2016, and to 23600 in 2017(Turkish Medical Association, 2018). Motivation is the probability of the individual to adopt, continue and adhere to the special strategies of change.MI is a directive and counselee-oriented approach, which is employed to help the patients explore and overcome the ambivalence/dilemma in adopting the behaviors that will enhance and improve their overall health. Studies conducted in recent years have found out that motivational interviewing technique is actually effective in parents' acceptance of childhood vaccines. The main purpose of the MI technique is to explore the ambivalences of the target individuals and attain behavioral change by helping them overcome such ambivalences. This method is particularly useful with parents that are hesitant or ambivalent to get their children vaccinated, or those that fail to get them vaccinated. In MI, which focuses on the parents' concerns, questions and curiosities about the vaccines, the behavioral change takes place depending on the personal values of each individual. MI is a special means of aid to help individuals understand their problems and encourage them to take action(Danchin et al.,2017). In order to enhance vaccination services, studies must be conducted on the issue of vaccine opposition and hesitancy of families, and underlying reasons must be revealed(Topçu et al.,2019; Akbaş,2020). Due to the fact that pregnancy and antenatal periods are the time spans when the first perspectives and beliefs about childhood vaccination are formed, these periods are particularly important for providing information pediatric vaccines. Determining the prevalence of vaccine opposition within the society, and monitoring it in upcoming years, as well as making programs on inspection and education, are assumed to be crucial in the struggle with vaccine hesitancy. This study is particularly important as it will help eradicate vaccine hesitancy through using Motivational Interviewing (MI) method and revealing the ambivalent emotions about vaccine hesitancy in pregnant women.
The success of vaccination programs often depends on the effectiveness of the vaccine messages, particularly during emergencies such as the COVID-19 pandemic. The current suboptimal uptake of COVID-19 vaccines across many parts of the world highlights the tremendous challenges in overcoming vaccine hesitancy and refusal even in the context of a world-devastating pandemic. The investigators conducted a randomized controlled trial in Hong Kong to evaluate the impact of seven vaccine messages on COVID-19 vaccine uptake (with the government slogan as the control). The participants included 127,000 individuals who googled COVID-19-related information during July-October 2021.
The aim of this study is to assess knowledge, beliefs and attitudes of parents to young girls aged 9 to 14 years about HPV vaccines within some rural communities in the North West Region of Cameroon served by three hospitals in that area. To do this, we will conduct in-depth qualitative interviews with purposively sampled parents of girls aged 9 to 14 years, some of whom received HPV vaccine and some of whom did not. Interviews will continue until thematic saturation is reached (We anticipate a total 40 interviews). Data analysis will be done concurrently with interviews using thematic analysis.
This is a randomised controlled experiment in the form of a web based survey study which randomly exposes participants to different forms of public health messages, after which participants will be assessed on their intent to take up the COVID-19 vaccine, recommend the vaccine, and also willingness to propagate the exposed message.
With the constant threat of new epidemic waves and the emergence of variants, COVID-19 resilience can only be attained when a sufficient level of immunity is achieved. Yet, in the US and the UK, COVID-19 vaccination campaigns have failed to secure consistent vaccination acceptance in racial/ethnic minority communities. Despite racial/ethnic minorities being more at risk from COVID-19, they are less vaccinated than the White majority. The investigators propose that current vaccination invitation messages are deemed less trustworthy by racial/ethnic minorities than the White majority and that this might partly explain reduced vaccination acceptance. To provide causal evidence of the role of trust and actionable insights, the investigators will experimentally assess the benefits of new invitation messages to receive the COVID-19 booster dose in large, racially/ethnically diverse samples in the US and the UK. Results will evidence how to increase message and source trustworthiness to foster trust and vaccination acceptance across racial/ethnic groups.
Oklahoma has high COVID-19 incidence, particularly among underserved minority and rural Oklahomans. Oklahoman's are also reporting SARS-CoV-2 vaccine hesitancy and signs of slowing vaccine uptake, with increased hesitancy among American Indian and rural populations. The project aims to work with ongoing community testing events to implement interventions to improve vaccine uptake among Oklahoma's underserved populations.
Many critical questions remain about the effectiveness of COVID-19 vaccines in real-world settings. These questions can only be answered in post-introduction vaccine effectiveness studies. This protocol describes a prospective one-year cohort study of hospital-based HWs in Baku city of Azerbaijan to evaluate the effectiveness of COVID-19 vaccine in preventing laboratory-confirmed SARS-CoV-2 infection and COVID-19 disease. HWs are the target population in this study because HWs have been prioritized to be the first group to receive the vaccine in Azerbaijan and offer an early opportunity to evaluate the vaccine in a population in which it is critical that an effective vaccine be deployed. HWs will be enrolled after the study protocol is approved by the local ethical review committee. All HWs eligible to be vaccinated with COVID-19 vaccine can be enrolled in the study, including those who intend to get vaccinated, those who don't plan on getting vaccinated, and those who are not sure. The target enrolment is 1500 HWs in six hospitals in Baku, the capital of Azerbaijan. At enrolment, study participants will complete a baseline enrolment e-survey about demographics, clinical comorbidities, and work- and community-related behaviours related to infection risk. In addition, a baseline serology will be collected from participants at enrolment. No PCR testing for COVID19 virus will be done at the time of enrollment. During the course of the study, participants will be actively followed for suspected symptomatic COVID-19 illness. Participants who meet a suspected case definition will be asked to have respiratory sample for SARS-CoV-2 by RT-PCR to be collected by trained HWs. PCR-positive samples from participants may also undergo genetic sequencing in or outside of Azerbaijan to identify the genetic makeup of the SARS-CoV-2 that caused the infection. Finally, at 6 months and 12 months of the study, serology will be collected from participants to confirm and quantify the immunity after vaccination as a secondary objective. Serology will be tested for antibodies to SARS-CoV-2. Serology samples will be stored and may be sent to laboratories outside of Azerbaijan for advanced serologic testing. Vaccine effectiveness should be analysed as described in the analysis section below. In addition to the final analysis at the end of the one-year period, interim quarterly (every three months) analyses will be undertaken.
The United States (U.S.) is the country with the largest number of infections and deaths due to COVID- 19 and racial/ethnic minorities are disproportionately affected. Acceptance and uptake of COVID-19 vaccines will be instrumental to ending the pandemic. To this end, 2VIDA! (SARS-CoV-2 Vaccine Intervention Delivery for Adults in Southern California) is a multilevel intervention to address individual, social, and contextual factors related to access to, and acceptance of, the COVID-19 vaccine by implementing and assessing a COVID-19 vaccination protocol among Latino and African American (AA) adults (>18 years old) in San Diego. 2VIDA! builds on our previous CBPR efforts and centers on conducting COVID-19 Individual awareness and education, linkages to medical and supportive services, and Community Outreach and Health Promotion in the intervention sites (Phase 1); and offering the COVID-19 vaccine to Latino and AA adults (>18 years old) in federally-qualified health centers and pop-up vaccination stations in communities highly impacted by the pandemic and identifying individual and structural barriers to COVID-19 immunization (Phase 2).
Healthcare workers (HCWs) play a vital role in determining the success of vaccination programs. Patient acceptance and vaccination rely greatly on the utilization and attitude of HCWs towards the vaccine, their attitude also influences patients' adherence to vaccination schedules and their hesitancy. HCWs themselves can be hesitant about a certain vaccine and thus can transfer their negative attitudes to their patients, increasing vaccine hesitancy among the general population. Frontline HCWs are at an increased risk of exposure to COVID-19 due to their direct contact with their patients, working hours, psychological stress and job burnout, they also face stigma. Dental health professionals in particular are at an increased risk due to their occupational hazards that include continuous exposure to body fluids and aerosols, this increases their risk of contracting COVID-19. Therefore vaccinating healthcare workers will be beneficial, not only for themselves, but also for their households and patients.
As Canada records over 1,400,000 COVID-19 infections and 26,000 deaths, the need to stop the spread of the virus has become increasingly critical. Although younger individuals (aged 20-39) have lower hospitalisation and death rates than older adults, they have high rates of infection and may be less willing to accept a vaccine because they consider the disease to be less dangerous for themselves. It is of concern that around 30% of Canadians, especially younger adults, will not be willing to accept a COVID-19 vaccine. Vaccination will be the best method to control the pandemic in the future and protect those at higher risk of hospitalisation and death (e.g., elderly, those with chronic diseases). Therefore, achieving high rates of vaccination coverage among younger adults is very important in the long run to protect not only themselves but also others. For the experimental condition, the investigators will develop a brief video that will promote the vaccine's protection of others (altruism). For the control condition, the investigators will create an informational text on COVID-19 preventative health measures based on recommendations from the Public Health Agency of Canada. 2630 younger adults (aged 20 to 39) who have not yet received a dose of a COVID-19 vaccine will be recruited. To match Canadian demographics, participants will be recruited using the following quotas to reflect census data from Statistics Canada: 50% male and 50% female; 80% Anglophone and 20% Francophone; 80% urban and 20% rural; and 50% household income level less than $75,000 and 50% household income greater than $75,000. Half of the participants will be randomly assigned to watch the video, with the other half reading the text. In both groups, participants will complete a short online survey before and after viewing the video or reading the text. The goal is to assess the efficacy of the video on increasing younger adults' willingness to get a COVID-19 vaccine. The research team is partnering in this study with key agencies, e.g., Public Health Agency of Canada (PHAC), National Advisory Committee on Immunization (NACI), and the Institut National de Santé Publique du Québec (INSPQ) to help communicate the research findings to the general population.
