An assessment of healthcare professionals' knowledge about and attitude towards influenza vaccination in Freetown Sierra Leone: a cross-sectional study

Knowledge and attitudes of healthcare workers about influenza vaccination

BACKGROUND

Influenza infection is a highly contagious viral disease. It may cause several nosocomial outbreaks. This study aimed to evaluate the knowledge and attitudes of healthcare workers (HCWs) about influenza vaccination and to identify factors associated with the uptake of influenza vaccination.

METHODS

We conducted a cross-sectional study over 5 months between November 2021 and March 2022. Data was collected using an anonymous self-administered questionnaire. We included all HCWs at Taher Sfar University Hospital who were willing to participate in the study.

RESULTS

A total of 395 HCWs were included. They were mainly women (78.7%) with an average age of 27 years. The medical personnel was the largest group (67.8%). Most respondents considered the vaccination to be optional and knew that it should be renewed every year, but 97.5% of them judged the efficacy of the vaccine to be low. The influenza vaccination uptake was only 20.2%. The main reasons for accepting vaccination were to protect patients and families. However, misconceptions about the severity and the risk of influenza and the belief that barrier measures were sufficient to prevent infection were the main causes of avoiding vaccination. The factors associated with adherence to vaccination were being a medical professional, old age, longer professional experience, and considering vaccination to be mandatory for HCWs.

CONCLUSION

Our study showed a low adherence to influenza vaccination with misconceptions about vaccine efficacy and safety. More efforts are needed to improve the knowledge of HCW about the vaccine and boost the adherence rates.

Influenza vaccination rates among healthcare workers: a systematic review and meta-analysis investigating influencing factors

Introduction

Healthcare workers risk of exposure to the influenza virus in their work, is a high-risk group for flu infections. Thus WHO recommends prioritizing flu vaccination for them-an approach adopted by >40 countries and/or regions worldwide.

Methods

Cross-sectional studies on influenza vaccination rates among healthcare workers were collected from PubMed, EMBASE, CNKI, and CBM databases from inception to February 26, 2023. Influenza vaccination rates and relevant data for multiple logistic regression analysis, such as odds ratios (OR) and 95% confidence intervals (CI), were extracted.

Results

A total of 92 studies comprising 125 vaccination data points from 26 countries were included in the analysis. The meta-analysis revealed that the overall vaccination rate among healthcare workers was 41.7%. Further analysis indicated that the vaccination rate was 46.9% or 35.6% in low income or high income countries. Vaccination rates in the Americas, the Middle East, Oceania, Europe, Asia, and Africa were 67.1, 51.3, 48.7, 42.5, 28.5, and 6.5%, respectively. Influencing factors were age, length of service, education, department, occupation, awareness of the risk of influenza, and/or vaccines.

Conclusion

The global influenza vaccination rate among healthcare workers is low, and comprehensive measures are needed to promote influenza vaccination among this population.

Uptake of Influenza Vaccine and Factors Associated with Influenza Vaccination among Healthcare Workers in Tertiary Care Hospitals in Bangladesh: A Multicenter Cross-Sectional Study

Influenza, highly contagious in hospital settings, imposes a substantial disease burden globally, and influenza vaccination is critical for healthcare workers (HCWs) to prevent this illness. This study assessed influenza vaccine uptake, including its associated factors among HCWs of tertiary care hospitals in Bangladesh. Between September and December 2020, this multicenter study included 2046 HCWs from 11 hospitals. Face-to-face interviews were conducted using a semi-structured questionnaire to collect data from physicians, nurses, and cleaning and administrative staff for the survey. Only 13.8% (283/2046) of HCWs received the influenza vaccine, of which the majority (76.7%, 217/283) received it for free from the hospital. Nurses had the highest (20.0%, 187/934) influenza vaccine coverage, followed by physicians at 13.5% (71/526), whereas cleaning staff had the lowest at 6.0% (19/318). Among unvaccinated HCWs, the desire to get vaccinated was high (86.2%), with half of the respondents even being willing to pay for it. The HCWs who were aware of the influenza vaccine were over five times more likely to get the vaccine (OR 5.63; 95% CI: 1.04, 1.88) compared to those who were not. HCWs in Bangladesh were vaccinated against influenza at a very low rate. Free and mandatory influenza vaccination programs should be initiated to optimize vaccine coverage among HCWs.

Knowledge, Attitude, Practice and Barriers Associated with Influenza Vaccination among Health Care Professionals Working at Tertiary Care Hospitals in Lahore, Pakistan: A Multicenter Analytical Cross-Sectional Study

Health Care Professionals (HCPs), including doctors, nurses, pharmacists, and paramedics, are a high-risk group for influenza infection due to their continuous exposure to patients having a known or unknown history of influenza-like illnesses. Influenza vaccination is the most effective method of primary prevention. This study was conducted to assess knowledge, attitude, practice, and barriers associated with influenza vaccination among HCPs at tertiary care hospitals in Lahore, Pakistan. A multicenter analytical cross-sectional study was conducted among HCPs. Data were collected using a structured questionnaire. All statistical analyses were conducted in R software. A total of 400 HCPs were enrolled, and among these, 67% had a high level of knowledge and 65.5% had a positive attitude towards influenza vaccination. About 51% of HCPs adopted good practices leading to influenza vaccination. Results identified major barriers for influenza vaccinations, including unfamiliarity with vaccine availability (RII = 0.760), insufficient staff for administering the vaccine (RII = 0.649), lack of proper storage (RII = 0.625), safety concerns (RII = 0.613), and cost of vaccine (RII = 0.602). More than half of the HCPs showed a high level of knowledge, a positive attitude, and good practice against influenza vaccination. Despite the positive Knowledge, Attitude, and Practice (KAP) scores and published guidelines, a very low percentage of HCPs were vaccinated against influenza. Many hindering factors were associated with influenza vaccination.

Knowledge, attitude and practices towards seasonal influenza vaccination among healthcare workers

Background

Vaccination as a primary prevention strategy is a well-established public health policy for preventing influenza. Despite strong recommendation, vaccination coverage among health workers is still not satisfying. The intention of the current study is to evaluate the knowledge, attitudes and practices towards influenza vaccination among healthcare workers.

Materials and Methods

In this cross-sectional, single-centre study, 789 healthcare workers (out of total 1380) participated. Institutional ethical committee clearance was obtained before the study. It was conducted in October 2021. A structured questionnaire in the form of Google sheet was sent to all healthcare professionals (HCPs) affiliated with the institution. Data collected was tabulated using MS Excel and analysed using appropriate statistical tools.

Results

Of the 1380 approached, a total of 789 (57.17%) HCPs responded to the questionnaire. The overall vaccination coverage in the study population was 71.6%. The overall vaccination acceptance rate drops to 36.78% when those taken vaccine as a recommended pre-employment requisite and got never vaccinated again were excluded. Also, 88.21% of the respondents believed that influenza is a potentially dangerous disease and 93.16% believed that flu vaccination is effective against preventing influenza. Although 736 participants (93.28%) were aware that seasonal influenza vaccine is recommended for healthcare workers, irrespective of age and comorbidities, only 411 (52.1%) intended to take vaccine in the coming year. Also, 97.34% of the participants considered vaccine as safe.

Conclusion

Influenza vaccination coverage among healthcare workers is still at an unsatisfactory level. This is despite majority of the HCPs accepting that the vaccine is safe and preventive against influenza. Efforts are still needed to improve the coverage.

Knowledge, attitudes and practices related to influenza and influenza vaccine among healthcare workers in Chongqing, China-a cross-sectional study

Influenza is associated with a substantial disease burden, and influenza vaccination is recommended to all healthcare workers. We aimed to assess healthcare workers' knowledge, attitudes, and practices about influenza and its vaccine in Chongqing, China. A cross-sectional study was conducted at selected hospitals from September to November 2019, in which healthcare workers filled in a self-administered questionnaire. Both sentinel (42.92%) and non-sentinel hospitals (57.08%) were included. The majority were nurses (52.48%) and physicians (32.37%). Half (50.42%) of the respondents had a good command of knowledge, and the proportion of healthcare workers having a positive attitude accounted for 62.68%. The primary information sources were colleagues (58.81%), followed by television, newspapers and media (30.18%). The number of healthcare workers reported having got vaccinated last year was only 237 (16.78%), and the main reason was protecting themselves from influenza (93.25%). While the most common reasons given for not getting vaccinated were having no time (65.70%), believing it is unnecessary to get vaccinated (29.62%), worrying about the quality of influenza vaccine (27.49%) or the adverse reactions (25.70%). Factors associated with self-reported high vaccination were sentinel hospital (aOR: 1.427; 95% CI: 1.057-1.925), high-risk department (aOR: 1.919; 95% CI: 1.423-2.589), positive attitude (aOR: 2.429; 95% CI: 1.697-3.477) and taking the initiative to learn influenza information (aOR: 3.000; 95% CI: 1.983-4.538). We concluded that healthcare workers in Chongqing had some misconceptions although many of them showed a positive attitude toward the influenza vaccine. Various strategies, including educational training and on-site vaccination, are necessary to improve the knowledge and overall vaccination coverage.

Attitude Towards COVID-19 Vaccination Among Healthcare Workers: A Systematic Review

INTRODUCTION

Availability and accessibility of a safe COVID-19 vaccine do not necessarily guarantee an effective means to mitigate the pandemic. However, the fragile hero's or health care worker's attitude toward the vaccine is of paramount importance to promote its acceptance. So, the current review aims to provide the latest assessment of healthcare workers' attitudes toward the COVID-19 vaccination and its contributing factor worldwide.

METHODS

Peer-reviewed surveys in English indexed via an electronic database in Google Scholar, Science Direct and PubMed were systematically searched. The review was carried out per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA-2009) and registered on PROSPERO (CRD42021265534).

RESULTS

Originally 8039 articles were searched from three databases PubMed, Science direct, and Google scholar. Finally, 24 studies met the inclusion criteria and made the root for the estimates of the attitude of COVID -19 vaccinations. In about two-thirds of the studies, respondents showed a positive attitude (≥50%) toward COVID-19 vaccination. However, in about one-quarter of the studies, a negative attitude (<50%) against vaccination was reported. Factors related to the attitude of healthcare workers toward COVID-19 vaccination include age, sex, profession, concerns about the safety of vaccines and fear of COVID-19, trust in the accuracy of the measures taken by the government, flu vaccination during the previous season, comorbid chronic illness, history of recommendation, and depression symptoms in the past week.

CONCLUSION

Although most studies report that healthcare workers have a positive attitude toward COVID-19 vaccination, quite a few surveys mention negative attitudes towards the use of vaccines, which may reflect missed opportunities or challenges for the international efforts aimed at mitigating the pandemic. Still, we need to continue to make more efforts to change the attitudes of the uncertain healthcare workers to increase the uptake of the vaccine and deal with the multi-faceted impact of infection.

Awareness, Attitude, and Current Practices Toward Influenza Vaccination Among Physicians in India: A Multicenter, Cross-Sectional Study

Background: Although annual influenza vaccination is recommended for healthcare providers (HCPs), vaccination rate among HCPs in India is generally low. This cross-sectional survey was conducted to evaluate physicians' awareness, attitude, and current practices toward influenza vaccination in high-risk groups in India.

Methods: The survey was performed in June–July 2020, wherein consulting physicians, pulmonologists, diabetologists, obstetricians/gynecologists, or cardiologists across 14 cities completed a 39-item questionnaire consisting of 3 sections, one each on awareness, attitude, and practice patterns. Descriptive statistics were used to summarize the study results. Statistical analysis was performed for comparison of subgroups by physician specialty, city of practice (metro/non-metro), and zone of practice (north/south/east/west). Level of statistical significance was set at p < 0.05.

Results: In all, 780 physicians completed the survey. Of these, 3.97, 53.08, and 42.95% had high, medium, and low level of awareness about influenza/influenza vaccination, respectively. Statistically significant (p < 0.05) between-group differences were found by physician specialty and zone of practice. In terms of attitude toward vaccination of high-risk group subjects, only 0.9% physicians were “extremely concerned,” while the majority (92.56%) were “quite concerned” and 6.54% were a “little concerned,” with no reported significant differences between different subgroups. With regard to practice patterns, 82.82% of physicians offered influenza vaccines to their patients, 32.69% vaccinated 10–25% of patients per month, and 38.85% required and offered the vaccine to their office staff. Physicians' reasons for not prescribing influenza vaccines to patients included fear of side effects (16.54%), cost (15.64%), lack of awareness about availability (15.38%), absence of belief that it is beneficial (14.36%), history of side effects (13.46%), and patients' fear of needles (11.28%).

Conclusion: These findings suggest the need to implement educational strategies among physicians to enhance their awareness about influenza vaccination and improve their attitudes and current practices toward influenza vaccination especially in high-risk groups in India.

Knowledge, attitudes, and practices for the use of seasonal influenza vaccination, healthcare workers, Costa Rica

INTRODUCTION

Annual seasonal influenza vaccination in healthcare workers prevents nosocomial transmission to patients, coworkers, and visitors, and reduces absenteeism. This study aimed to describe knowledge, attitudes, and practices (KAP) of seasonal influenza vaccine among public healthcare workers attending patients in Costa Rica.

METHODOLOGY

We conducted a cross-sectional survey of healthcare personnel attending patients in public hospitals in 2017-2018. Frequency distributions of demographics, vaccination KAP, sources of information, clinical manifestations and reasons for non-vaccination were reported. Logistic regression was used to analyze associations between exposures of interest (demographics, sources of information, knowledge, attitudes towards vaccination) and self-reported influenza vaccination.

RESULTS

We surveyed 747 healthcare workers in 2017-2018. Of 706 participants who knew their vaccination status, 55.7% were vaccinated for seasonal influenza. Only 20.7% of participants knew the influenza vaccine was an inactivated virus, and 94.6% believed the vaccine causes flu-like symptoms. Factors associated with current influenza vaccination were vaccination in previous year (aOR: 8.13; 95% CI: 5.65-11.71) and believed influenza vaccination may be harmful (aOR: 0.62; 95% CI: 0.44-0.89). Reasons for non-vaccination included fear of adverse effects and access limitations.

CONCLUSIONS

Suboptimal influenza vaccination among healthcare workers may be attributed to misconceptions about the vaccine and limited engagement strategies focusing on healthcare workers. Appropriate interventions are needed to increase healthcare worker vaccination rates and improve their knowledge and beneficence, which would improve patient safety in hospitals.

Are malaria transmission-blocking vaccines acceptable to high burden communities? Results from a mixed methods study in Bo, Sierra Leone

BACKGROUND

Malaria transmission-blocking vaccines (TBVs) could help break the cycle of malaria transmission by conferring community rather than individual protection. When introducing new intervention strategies, uptake is dependent on acceptability, not just efficacy. In this exploratory study on acceptability of TBVs in Sierra Leone, it was hypothesized that TBVs would be largely acceptable to adults and health workers in areas with relatively few ongoing malaria interventions, and that (i) knowledge of malaria and vaccines, (ii) health behaviours associated with malaria and vaccines, and (iii) attitudes towards different vaccines types could lead to greater TBV acceptability.

METHODS

This study used a mixed methods approach in Bo, Sierra Leone, to understand community knowledge, attitudes, and practices related to malaria and vaccination in general. This included: (i) a population-based cross-sectional survey (n=615 adults), (ii) 6 focus group discussions with parents, and (iii) 20 key informant interviews. The concept of a TBV was explained to participants before they were asked about their willingness to accept this vaccine modality as part of an integrated malaria elimination programme.

RESULTS

This study found that most adults would be willing to receive a TBV vaccine. Respondents noted mostly positive past experiences with adult and childhood vaccinations for other infectious diseases and high levels of engagement in other malaria prevention behaviors such as bed nets. Perceived barriers to TBV acceptance were largely focused on general community-level distribution of a vaccine, including personal fears of vaccination and possible costs. After an explanation of the TBV mechanism, nearly all focus group and interview participants believed that community members would accept the vaccine as part of an integrated malaria control approach. Both parents and health workers offered insight on how to successfully roll-out a future TBV vaccination programme.

CONCLUSIONS

The willingness of community members in Bo, Sierra Leone to accept a TBV as part of an integrated anti-malarial strategy suggests that the atypical mechanism of TBV action might not be an obstacle to future clinical trials. This study's findings suggests that perceived general barriers to vaccination implementation, such as perceived personal fears and vaccine cost, must be addressed in future clinical and implementation research studies.

Knowledge, attitudes, and practices of seasonal influenza vaccination in healthcare workers, Honduras

Background

Seasonal influenza is a highly contagious vaccine-preventable disease that may cause high morbidity and mortality in susceptible populations. Healthcare workers are a priority group for seasonal influenza vaccination to protect them from contracting influenza and prevent nosocomial transmission to patients. This study aimed to evaluate knowledge, attitudes, and practices (KAP) of seasonal influenza vaccination among healthcare workers in Honduras.

Method

From August 24 to October 21, 2018, we conducted a cross-sectional KAP survey regarding seasonal influenza vaccination to a random sample of healthcare workers who attended patients in hospitals of the Ministry of Health of Honduras (SESAL) and Honduran Social Security Institute (IHSS). We reported frequency distributions of demographics, vaccination KAP, sources of information, and reasons for non-vaccination. We used principal components factor analysis to create knowledge and attitude scores. We used linear regression to analyze associations between demographics and sources of information about the influenza vaccine, and knowledge and attitude scores. We used logistic regression to analyze associations between demographics, sources of information, knowledge scores, and attitude scores, and influenza vaccination.

Result

We surveyed 947 healthcare workers who attended patients in 13 SESAL hospitals and two IHSS hospitals. Only 4.6% of participants knew the seasonal influenza vaccine was composed of inactivated viruses, 94.7% believed vaccination causes flu-like symptoms, and 52.0% were vaccinated for influenza in 2018. Knowledge scores were lower for nursing assistants and other healthcare professionals compared to doctors, and higher for healthcare workers who attended a healthcare facility training (P-values≤0.030). Attitude scores were higher for healthcare workers who attended ≥11 patients per day having ≤10 patients per day as reference, self-reported influenza vaccination in previous year, and cited trainings and informal information at the healthcare facility as sources of information for influenza vaccination (P-values≤0.030). Factors associated with self-reported vaccination were self-reported influenza vaccination in previous year (aOR: 7.61; 95% CI: 5.24–11.04), attitude score (aOR: 1.14; 95% CI: 1.07–1.21), and worked in a SESAL hospital (aOR: 1.73; 95% CI: 1.12–2.68) having IHSS as reference.

Conclusion

Although influenza vaccination is required by law in Honduras and available for free in public health centers, coverage of healthcare workers in 2018 was half that reported in 2017. Lower coverage may be attributed to misconceptions of vaccination side effects.

Correlates of Health Care Workers' Knowledge and HIV-Exposed Infant Immunization Counseling Practice in Northern Nigeria

BACKGROUND

Human Immunodeficiency Virus (HIV)-exposed and HIV-infected infants are at increased risk of vaccine-preventable diseases. However, little is known about health care workers' knowledge and immunization counseling practices in this population. We determined the predictors of health care workers' knowledge of vertical transmission risks, HIV exposed/infected infant immunization, and counseling practices in a tertiary center in Northern Nigeria.

METHODS

A cross-section of 297 health workers were interviewed using a structured, validated questionnaire. Knowledge and HIV-exposed infant immunization counseling practices were analyzed, and adjusted odds ratios for predictors were derived from logistic regression models.

RESULTS

Of the 297 participating health care workers, (32.3%, n=96) had adequate knowledge of HIV-exposed/infected infant immunization. Two-thirds (67%, n=199) of the participants appropriately identified the timing of infant diagnosis, while (73%, n=217) and (56.2%, n=167) correctly categorized infants as HIV-exposed and HIV-infected, respectively. Only (19.5%, n=58) participants had ever counselled a HIV-positive mother on infant immunization. Knowledge was predicted by work unit (HIV clinic vs. Obstetrics & Gynecology clinic), (Adjusted Odds Ratio (AOR) =3.78, 95% CI: 1.27-5.54), age (30-39 vs. <30 years), (AOR=2.24, 95% CI:1.19-5.67), years of experience (≥10 vs. <5), (AOR=1.76, 95% CI: 1.15-6.04), number of children (1 vs. 0), (AOR=1.73, 95% CI:1.14-4.23), infant immunization training (yes vs. no), (AOR=1.57, 95% CI:1.12-5.43), female sex (AOR = 1.17, 95% CI:1.06-2.21), profession (nurse/midwife vs. physician), (AOR=0.44, 95% CI:0.21-0.94) and previous HIV test (no vs. yes), (AOR=0.67, 95% CI:0.21-0.83).

CONCLUSION AND GLOBAL HEALTH IMPLICATIONS

Knowledge of HIV-exposed infant immunization was low and counseling practices were sub-optimal. Both immunization knowledge and counseling practices were predicted by demographic, professional, and training variables. Our findings indicate the need for educating health care workers on HIV exposed/infected infant immunization policy and improving counseling skills through capacity-building programs.

Knowledge and practice of vaccination logistics management among primary health care workers in Nigeria

Vaccines are highly thermo-sensitive materials whose potency requires a functional cold chain system which is dependent on the ability of health care workers to effectively manage the system toward eliminating vaccine-preventable diseases.This study assessed knowledge and practice of vaccination logistic management systems among primary health care workers in Osun state Nigeria.It was a descriptive cross-sectional study among 180 randomly selected health care workers who took part in a larger study on the design and pretesting of vaccine cold chain (VACOC) coolers. Research instruments were self-administered semi-structured pretested questionnaire that was analyzed using the SPSS version 23.0.The mean age was 36.7 ± 8.9 years, 87 (48.3%) could correctly explain the vaccination logistic management system, 132 (73.3%) had been trained on the system, 129 (71.7%) could assemble the ice packs used in the vaccine career box, 135 (75.0%) could assemble the vaccines, while 145 (80.6%) could assemble the diluents and thermometer. One hundred and fifty-one (83.9%) and 146 (81.1%) were found to have good knowledge and attitude to the management systems, respectively. Spending more than 5 years in profession, being a male, being a Community Health Officer were significant predictors of having a good practice of immunization logistic management system.Some gaps in knowledge, attitude, and practice of vaccination cold chain logistic system still exist among studied respondents, and these should be addressed by stakeholders in immunization programs.

Nursing knowledge, attitude, and practice to influenza vaccination at suburban hospital in West Java, Indonesia

BACKGROUND

High epidemiology of influenza in the world and Indonesia causes some groups to have high risk for getting infected with influenza, one of which is healthcare workers. The low rates of influenza vaccination among healthcare workers, especially in nurses, raise the need for an educational strategy to prevent influenza. This study aimed to measure the level of knowledge, attitude and practice among nurses in suburban hospital in West Java.

METHOD

This was a cross-sectional study with a random sampling method which started on July-August 2018 at Annisa Medical Center General Hospital. Knowledge, attitude, and practice of research subjects were measured using questionnaire containing 37 items. The questionnaire was the result of adaptation of several questionnaires and a validity test has been was conducted. The data obtained was then analyzed descriptively by the proportion of the score of knowledge, attitude, and practice.

RESULTS

Of 104 respondents, 19% respondents had a low level, 74% respondents had a moderate level and 7% had a high level of knowledge toward influenza vaccination. For attitude, 67% of the respondents had a positive attitude and 33% respondents had a negative attitude. The study also showed that 58% of the respondents had a positive practice and 42% respondents had negative attitude.

CONCLUSIONS

Nurses possess adequate knowledge and showed a positive attitude and practice toward influenza vaccination. A continous educational strategy was needed to improve nurses' knowledge, attitude and practice about influenza vaccination.

Healthcare professionals' knowledge, attitude and acceptance of influenza vaccination in Saudi Arabia: a multicenter cross-sectional study

Background

All healthcare professionals (HCPs) are at high risk of influenza infection. Therefore, immunization is recommended for all HCPs. Due to safety and effectiveness concerns, HCPs have a low vaccination rate. This study was designed to explore the attitude, awareness and knowledge of HCPs toward vaccination for influenza.

Method

A cross-sectional study was performed during October–November 2016. A total of 405 questionnaires were distributed in 8 major hospitals in Saudi Arabia. A validated questionnaire consisting of 31 questions and 5 sections was administered. Statistical Analysis Software (SAS®) version 9.2 was used to analyze the data.

Results

A total of 364 HCPs responded to the study survey, which is a response rate of 90%. A large proportion (61.8%) of participants were female. The majority of the participants were nurses (60.4%). More than half of the respondents (57.7%) were working in government-run hospitals. Among all the participants, approximately 67.6% of HCPs were vaccinated. The majority (84.1%) of HCPs believed that influenza vaccine prevents the flu. Furthermore, approximately 75% of participants believed that HCPs can be more susceptible to influenza infections than other people. The majority of participants (89.6%) knew the proper signs and symptoms of influenza. HCPs’ belief that vaccination prevents influenza infection (OR = 3.93, 95% CI = 1.97–7.82), their awareness of the Scientific Committee for Influenza and Pneumococcal Vaccination (SCIPV)‘s guidelines (OR = 2. 13, 95% CI = 1.16–3.90) and the presence of the standing orders regarding influenza vaccine (OR = 1.57, 95% CI = 1.01–3.21), were the predictors for receipt of influenza vaccine by HCPs.

Many (58.0%) respondents believed that vaccine safety concerns is a major barrier to the vaccination of HCPs. Some misconceptions, such as influenza infection due to vaccination (42.3%) and incorrect perceptions about the symptoms of influenza in adults (50.5%), were found.

Conclusion

The acceptance of and participation in influenza vaccination by HCPs in Saudi Arabia appears to have markedly increased in the 2016 season. Continuing evaluation of vaccination practices is necessary, and more training programs are needed in the future.

Knowledge, Attitude, Awareness, and Barriers Toward Influenza Vaccination Among Medical Doctors at Tertiary Care Health Settings in Peshawar, Pakistan-A Cross-Sectional Study

Objective: This study intends to evaluate the knowledge, attitude and awareness of medical doctors toward influenza vaccination and the reasons for not getting vaccinated. Methods: A cross-sectional study was carried out among medical doctors in three major tertiary care health settings in Peshawar, Khyber Pakhtunkhwa (KP), Pakistan. A web-based, pre-tested questionnaire was used for data collection. Results: A total of (n = 300) medical doctors were invited, however only (n = 215) participated in the study with a response rate of 71.7%. Among the participants, 95.3% (n = 205) were males with a mean age of 28.67 ± 3.89 years. By designation, 121(56.3%) were trainee medical officers and 40 (18.6%) were house officers. The majority 102(47.4%) had a job experience of 1-2 years. Of the total sample, 38 (17.7%) doctors reported having received some kind of vaccination, whereas only 19 (8.84%) were vaccinated against influenza. The results identified that the major barriers toward influenza vaccinations included (1) Unfamiliarity with Influenza vaccination availability (Relative Importance Index RII = 0.830), (2) Unavailability of Influenza vaccines due to lack of proper storage area in the institution (RII = 0.634), (3) Cost of vaccine (RII = 0.608), and (4) insufficient staff to administer vaccine (RII = 0.589). Additionally, 156 (72.6%) of doctors were not aware of the influenza immunization recommendation and guidelines published by the Advisory Committee on Immunization Practices (ACIP) and Centre for Disease Control and Prevention (CDC). Physicians obtained a high score (8.27 ± 1.61) of knowledge and understanding regarding influenza and its vaccination followed by medical officers (8.06 ± 1.37). Linear Regression analysis revealed that gender was significantly associated with the knowledge score with males having a higher score (8.0± 1.39) than females (6.80 ± 1.61 β = -1.254 and CI [-2.152 to -0.355], p = 0.006). Conclusion: A very low proportion of doctors were vaccinated against influenza, despite the published guidelines and recommendations. Strategies that address multiple aspects like increasing awareness and the importance of the influenza vaccine, the international recommendations and enhancing access and availability of the vaccine are needed to improve its coverage and health outcomes.

Acceptability of intranasal live attenuated influenza vaccine, influenza knowledge and vaccine intent in The Gambia

BACKGROUND

The burden of influenza is increasingly recognised in Africa. The WHO recommends introducing influenza vaccination to high-risk groups: pregnant women, children <5 years, and the elderly. The Gambia currently has no influenza vaccination policy, but the NASIMMUNE study, a clinical trial of intranasal live attenuated influenza vaccines (LAIV) in young children provided an opportunity to study maternal attitudes towards LAIV for the first time in sub-Saharan Africa. We assess acceptability of LAIV, influenza knowledge and attitudes towards influenza vaccination in Gambian women. Additionally, we investigate predictors of willingness to receive influenza vaccine (intent) in pregnancy or seasonally for children <5.

METHODS

A cross-sectional survey was conducted in Gambian women at two urban health facilities. To assess LAIV acceptability, the exposure group (women whose children had received LAIV during the NASIMMUNE study) were compared to a control group (women whose children were not enrolled in the NASIMMUNE study). Demographics and health belief constructs were analysed as predictors of influenza knowledge and vaccine intent.

FINDINGS

The exposure group (n = 150) expressed a higher preference for a nasal spray vaccine than an injection compared to the control group (n = 304) (93.3% vs. 34.9%, OR = 26.15, p < 0.0001). Those in the exposure group who preferred the nasal spray found it less distressing, safer or equally safe, and easier or equally easy to give (all p < 0.001) than injections. Influenza knowledge increased with education level (p = 0.006 for higher education vs. none), and varied between sites (p = 0.0005). Vaccine intent was >98%, but no association with influenza knowledge or difference between groups was observed. Various health belief constructs were associated with vaccine intent.

CONCLUSION

LAIV acceptability was higher in those with first-hand experience. Influenza vaccine intent was also high. Incorporation of seasonal LAIV into the childhood immunisation schedule in The Gambia would be feasible, particularly if combined with community-based health education.
