Methods and Objectives.To estimate infant vaccination coverage in the French-speaking region of Belgium (Wallonia) and in the Brussels-Capital Region, two cross-sectional studies were performed in 2012. A face-to-face questionnaire was administered by trained investigators. The objective was to evaluate infant vaccination coverage retrospectively in 18- to 24-month-old children. These studies offered the opportunity to assess some factors influencing vaccine uptake in infants.Results and Discussion.Approximately 99% of the children had received the first dose of IPV-DTaP, 90% the fourth dose, 94% the MMR vaccine, 97% the first dose of pneumococcal vaccine, and 90% the third dose. In both regions, when fitting a logistic model, the most associated factor was attendance at maternal and child clinics (MCH). No association was observed between vaccination coverage and the mother’s level of education. For the last immunization session, where the mother was a Belgian native and when she worked more hours, child was better immunized, but only in Brussels.Conclusion.Coverage for the fourth dose of hexavalent vaccine (DTaP-IPV-HBV/Hib) needs to be increased. Indeed, additional effort is needed to increase HIB and pertussis coverage rates because the herd immunity threshold for these two diseases has not been reached.

Abstract Background Seasonal influenza vaccination (SIV) of health care workers (HCWs) is well recognized as a public health measure that can protect both HCWs from infection and patients from the risk of influenza complications. Nevertheless, vaccination coverage rates among this specific population result generally lower than the recommended target. With our study, we aimed to describe the activities and the outcomes of four different SIV campaigns targeted at HCWs and organized during the season 2018/2019 in four hospitals in Rome. Methods A cross-sectional study involving four teaching hospitals was performed. The collected data were synthetized into a set of descriptors and indicators, validated through a previous study that had involved the same Centers. Results The Medical Directorates, in collaboration with the University Hygiene and Public Health Units of the four hospitals organized different strategies: Hospital 1, 3 and 4 realized educational courses for HCWs and actively promoted the campaigns through e-mail invitations to all HCWs. As for the access to vaccination, all the hospitals provided a dedicated unit for SIV; Hospital 1 and Hospital 4 organized also on-site vaccination sessions in the hospital wards, that required a large number of staff. The vaccination coverage rates resulted: 22.37% in Hospital 1, 18.10% in Hospital 4, 9.28% in Hospital 2 and 8,51% in Hospital 3. Conclusions Our results demonstrate that multi-activity campaigns, involving education, promotion and easy access to vaccination constitute an effective approach to reinforce the value of SIV. Our findings suggest that on-site vaccination may play a key role in determining a higher vaccination coverage. Key messages Multi-activity vaccination campaigns, involving education, promotion and easy access to vaccination constitute an effective approach to reinforce the value of seasonal influenza vaccination for HCWs. On-site vaccination may play a key role in determining a higher vaccination coverage.

While vaccination is the only established option to prevent a susceptible host from influenza, we have yet to clarify the decision-making mechanisms of vaccine uptake among Japanese university and college students. We aimed to explore vaccination coverage and the related demographic, sociocultural, and socioeconomic factors among university students. We performed a cross-sectional survey involving 604 students at Hokkaido University. Participants were asked if they received influenza vaccination in advance of the 2018/19 season, and subsequently, their demographic and sociocultural/socioeconomic characteristics were surveyed. We also explored the mechanisms underlying students’ vaccination decisions. Vaccination coverage was estimated at 27.3% (95% confidence interval: 23.7–30.9). Freshmen (p < 0.0001) were significantly associated with choosing vaccination, and their odds ratio of vaccination was 11.3 (95% confidence interval: 6.2–20.7) times greater than students in other years. Among students other than freshmen, students belonging to medicine- and healthcare-related faculties were vaccinated three times more frequently than other students, and the coverage in students from Hokkaido was twice as large as that for students from other prefectures. Moreover, extracurricular activity was a positive predictor of vaccination. Although the coverage was as small as 27.3% among university students, freshmen in Japan have high vaccination coverage, which we believe is associated with the entrance examination during high influenza activity. In addition to exposing students to proper education regarding their risk self-assessment, consciousness raising via appropriate understanding of influenza and its severity and offering vaccination at university health centers at a reasonable cost may promote vaccine acceptance.

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.

Dog-mediated human rabies remains a major public health threat in Nigeria. The availability of reliable dog population estimates is the key in planning control strategies for canine rabies in developing countries. This study was conducted to evaluate the demography of dogs in Umuahia, Abia State, Nigeria. A cross sectional study was carried out in Umuahia North and Umuahia south, Local Government areas (LGA) Abia state, Nigeria, between September and November 2019. A total of 132 compounds in Umuahia North and 186 compounds in Umuahia South were randomly selected for administration of questionnaires. A total of 159 questionnaires were distributed for compound dog count. Information obtained included household information such as numbers of dogs in the premises, housing and control of dog movement. Others were history of dog bites and individual dog information such as breed, sex, age, source of dog, source of food and vaccination status. Two hundred and fifty-seven (257) dogs were counted which comprised 126 (49%) males and 131 (51%) females. Also, 46.3% of the dogs were confined. The dog vaccination coverage in the dog population surveyed was 47.9%. Majority of the respondents (83.3%) stated that no member of their family has been bitten by a dog. The findings of this study show female: male ratio of dog to be 1.04:1. There was negligent dog ownership as a good number of dogs were left to roam. There was a low anti-rabies vaccination coverage in Umuahia North and Umuahia South LGAs which falls below recommendation of 70-80% vaccination coverage by the World Health Organization to achieve herd immunity.

Hepatitis B vaccination coverage rates are low throughout most populations in China. Factors influencing low coverage rates, including population-specific hepatitis B vaccination barriers, may inform policies that promote vaccination. A cross-sectional survey of residents from 43 communities assessed their vaccination status and identified associated factors via uni- and multivariable logistic regression and subgroup analyses. In total, 11,280 of 36,007 respondents received a hepatitis B vaccine, indicating a 31.33% coverage rate. Multivariable logistic regression revealed non-Beijing (odds ratio (OR) = 0.81; 95% confidence interval (CI): 0.76–0.85) and residents who self-rated their health as very healthy (OR = 0.82; 95% CI: 0.68–0.99) were unlikely to be vaccinated. Farmers (OR = 1.68; 95% CI: 1.51–1.86), commerce and service workers (OR = 1.82; 95% CI, 1.63–2.04), government employees (OR = 1.56; 95% CI: 1.38–1.77), professionals and technicians (OR = 1.85; 95% CI: 1.63–2.09), and students (OR = 1.69; 95% CI: 1.10–2.59) had increased hepatitis B vaccination rates. The multivariable assessment revealed hepatitis B vaccination coverage rates are associated with confirmed or suspected family cases, vaccination unwillingness or uncertainty, and unawareness of its prevention of the hepatitis B virus. Low hepatitis B vaccination coverage rates among Beijing subpopulations highlight the need for improved strategies, including those that target specific populations.

AbstractBackgroundIncreased vaccine hesitancy and refusal negatively affects vaccine uptake leading to vaccine preventable disease reemergence. We aimed to quantify the relative importance of characteristics people consider when making vaccine decisions for themselves, or for their child, with specific attention for underlying motives arising from context, such as required effort (accessibility) and opportunism (free riding on herd immunity).MethodsWe documented attitudes towards vaccination and performed a discrete choice experiment in 4802 respondents in The United Kingdom, France and Belgium eliciting preferences for six attributes: (1) vaccine effectiveness, (2) vaccine preventable disease burden, (3) vaccine accessibility in terms of co-payment, vaccinator and administrative requirements, (4) frequency of mild vaccine-related side-effects, (5) vaccination coverage in the country’s population and (6) local vaccination coverage in personal networks. We distinguished adults deciding on vaccination for themselves (‘oneself’ group) from parents deciding for their youngest child (‘child’ group).ResultsWhile all six attributes were found to be significant, vaccine effectiveness and accessibility stand out in all (sub)samples, followed by vaccine preventable disease burden. We confirmed that people attach more value to severity of disease compared to its frequency and discovered that peer influence dominates free-rider motives, especially for the vaccination of children.ConclusionsThese behavioral data are insightful for policy and are essential to parameterize dynamic vaccination behavior in simulation models. In contrast to what most game theoretical models assume, social norms dominate free-rider incentives. Therefore policy-makers and healthcare workers should actively communicate on high vaccination coverage, and draw attention to the effectiveness of vaccines, while optimizing their practical accessibility.

Vaccination Programs

Background and objectives: Vaccine hesitancy is a big obstacle for vaccination programs, as is anticipated for the COVID-19 vaccination program, resulting in low uptake of vaccines thereby hindering the process of reaching herd immunity. Bearing this in mind the current study was aimed to explore the determinants of vaccine hesitancy amongst the Pakistani population. Methodology: A cross-sectional study was carried out from the 23rd-31st January 2021. The conceptual framework of the study was based on the 3Cs (Confidence, Convenience, Complacency) model. Google-forms-based questionnaire was disseminated amongst the general population. Data collected were entered into SPSS version 26 and analyzed. Results: Of the 421 participants, 68.4% were females. Non-healthcare workers were 55.8% of respondents. Vaccine hesitant individuals, 26.13% reported they were very unlikely to get vaccinated. Vaccine was not safe as it came out too fast was agreed upon by 12.6% individuals, 50.6% were worried about experiencing side-effects, 18% believed vaccine will not offer protection and 5.9% believed vaccine would cause death. Low Practice of SOP in non-Healthcare workers was the strongest contributor to vaccine hesitancy (OR: 5.338, p=0.040, 95% CI: 1.082-26.330) followed by High complacency (p=0.026) and Moderate Complacency (OR: 0.212, p=0.007, 95% CI: 0.069-0.654) towards COVID-19 vaccination. In Healthcare workers the strongest contributor to vaccine hesitancy was having a Moderate Confidence (OR: 0.323, p=0.042, 95% CI: 0.109-0.958) in the vaccine followed by Moderate Convenience (OR: 0.304, p=0.049, 95% CI: 0.093-0.993) for vaccination Conclusion: Campaigning and communication strategies to reaffirm confidence in the COVID-19 vaccine and educating the general population about the vaccine could lead to increased perception of vaccine safety and effectiveness thereby restoring confidence in vaccine and decreasing vaccine hesitancy. Likewise, working to increase vaccine convenience and decreasing complacency towards the COVID-19 vaccine would translate into high vaccine uptake.

Dogs (Canis familiaris) are often free-roaming in sub-Saharan African countries. Rabies virus circulates in many of these populations and presents a public health issue. Mass vaccination of dog populations is the recommended method to decrease the number of dog and human rabies cases. We describe and compare four populations of dogs and their vaccination coverage in four different villages (Hluvukani, Athol, Utah and Dixie) in Bushbuckridge Municipality, Mpumalanga province, South Africa. Cross-sectional surveys were conducted in the villages of Athol, Utah and Dixie, while data from a Health and Demographic Surveillance System were used to describe the dog population in Hluvukani village. All households of the villages were visited to obtain information on the number, sex, age and rabies vaccination status of dogs. From May to October 2013, 2969 households were visited in the four villages and 942 owned dogs were reported. The populations were all young and skewed towards males. No differences were observed in the sex and age distributions (puppies 0–3 months excluded) among the villages. Athol had a higher proportion of dog-owning households than Hluvukani and Utah. Vaccination coverages were all above the 20% – 40% threshold required for herd immunity to rabies (38% in Hluvukani, 51% in Athol, 65% in Dixie and 74% in Utah). For the preparation of vaccination campaigns, we recommend the use of the relatively stable dog:human ratio (between 1:12 and 1:16) to estimate the number of dogs per village in Bushbuckridge Municipality.
