RESUMEN
Obtaining a booster dose of coronavirus disease 2019 (COVID-19) vaccine is required to maintain the protective level of neutralizing antibodies and therefore herd immunity in the community, and the success of booster dose programs depends on public acceptance. The aim of this study was to determine the acceptance of a booster dose of COVID-19 vaccine and its drivers and barriers in Indonesia. A cross-sectional survey was conducted in the provinces of Indonesia between 1 and 15 August 2022. Individuals who completed the primary series of the COVID-19 vaccine were asked about their acceptance of a booster dose. Those who refused the booster dose were questioned about their reasons. A logistic regression was used to determine the determinants associated with rejection of a booster dose of COVID-19 vaccine. A total of 2935 respondents were included in the final analysis. With no information on the efficacy and safety of the COVID-19 vaccine, 95% of respondents agreed to receive a booster dose if it were provided for free by the government. This acceptance was reduced to only 50.3% if the vaccine had a 75% efficacy with a 20% chance of side effects. The adjusted logistic regression analysis indicated that there were eight factors associated with the rejection of the booster dose: age, marital status, religion, occupation, type of the first two vaccines received, knowledge regarding the importance of the booster dose, belief that natural immunity is sufficient to prevent COVID-19 and disbelief in the effectiveness of the booster dose. In conclusion, the hesitancy toward booster doses in Indonesia is influenced by some intrinsic factors such as lack of knowledge on the benefits of the booster dose, worries regarding the unexpected side effects and concerns about the halal status of the provided vaccines and extrinsic determinants such as the effectiveness and safety of the vaccine. These findings suggest the need for more campaigns and promotions regarding the booster dose benefits to increase its acceptance.
RESUMEN
Willingness to pay (WTP) for booster doses of coronavirus disease 2019 (COVID-19) vaccines is an under studied research topic. Therefore, the current study aimed to investigate the WTP for the booster doses of COVID-19 vaccines and its predictors in Indonesia using an online survey distributed all over the provinces of this low-middle-income country. The WTP was evaluated using a basic dichotomous contingent valuation approach, and its associated determinants were evaluated using a linear regression model. Out of 2935 responders, 66.2% (1942/2935) were willing to pay for a booster dose of the COVID-19 vaccine. The majority of respondents (63.5%) were willing to pay within a price range of 100,000-500,000 Indonesian rupiah (IDR), i.e., USD 6.71-33.57. Being older than 40 years, having a higher educational level, having a higher income, knowing and understanding that booster doses were important, and having a vaccine status that is certified halal (permissible in Islamic law), were all associated with a higher WTP for the booster dose of COVID-19 vaccines. The study findings imply that the WTP for a booster dose of COVID-19 vaccination in Indonesia is lower compared to acceptance of vaccines provided free of charge. This WTP data can be utilized to develop a pricing scheme for the booster doses of COVID-19 vaccination in the country with potential benefits in other low-income countries. The government may be required to provide subsidies for the herd immunity vaccination process to proceed as anticipated. Furthermore, the public community must be educated on the importance of vaccination as well as the fact that the COVID-19 epidemic is far from being over.
RESUMEN
Background: Although there is no licensed vaccine for monkeypox, smallpox vaccine has been shown to be 85% effective in preventing the monkeypox. This study was conducted to assess the willingness of frontline healthcare providers to be vaccinated with smallpox vaccine to prevent monkeypox. Methods: A cross-sectional study was conducted in Indonesia. The willingness was assessed under two scenarios: fully subsidized and non-subsidized vaccine. Explanatory variables such as sociodemographic profile, workplace and professional characteristics, and knowledge of monkeypox were collected. A logistic regression assessed the influence of these explanatory variables on participants' willingness. Results: Out of 510 received participants' responses, 407 (79.8%) were analyzed. With a fully subsidized vaccine scenario, 381 (93.6%) of the participants were willing to be vaccinated and in an unadjusted analysis, gender, education, monthly income, and type of workplace were associated with willingness. With a non-subsidized vaccine (i.e. the vaccine price was US$ 17.9), the proportion who were willing to be vaccinated decreased to 71.9%. In adjusted analyses for both scenarios, gender was the only independent predictor for willingness; men were less willing to be vaccinated than women, adjusted odds ratio (aOR): 0.37; 95% confidence interval (CI): 0.16, 0.87 and aOR: 0.42; 95%CI: 0.27, 0.67, respectively for subsidized and non-subsidized scenario. Conclusion: Vaccine price and gender are important factors for physicians' willingness to be vaccinated for smallpox vaccine prevent monkeypox in Indonesia. These findings indicate that achieving high vaccine converge may require partially or fully subsidized vaccines, along with a clear guideline and recommendation from authorities.
RESUMEN
After the first, imported, laboratory-confirmed case of monkeypox in human was reported in Singapore on May 2019, countries in Asia started to strengthen disease surveillance systems. One challenge in preventing monkeypox is a lack of knowledge, particularly among healthcare workers. The aim of this study was to assess the knowledge of monkeypox among general practitioners (GPs) in Indonesia. A cross-sectional online survey was conducted. The survey collected participants' knowledge on a 21-item scale and explanatory variables. A two-step logistic regression analysis was employed to assess the predictors of knowledge of monkeypox. A total of 432 GPs were included; 10.0% and 36.5% of them had a good knowledge using an 80% and 70% cutoff point for knowledge domain, respectively. No explanatory variables were associated with knowledge when using 80% cutoff point. Using the lower cutoff, there was lower knowledge among GPs who graduated from universities located in Sumatra or other islands versus Java (adjusted odds ratio (aOR): 0.53; 95%CI: 0.28-0.97, p = 0.041) and among those were older than 30 years compared to younger GPs (aOR: 0.61; 95%CI: 0.39-0.96, p = 0.033). GPs working in private clinics had less knowledge compared to GPs in community health centers (aOR: 0.55; 95%CI: 0.31-0.99, p = 0.047). In conclusion, knowledge of monkeypox among GPs in Indonesia is relatively low in all groups. Increasing knowledge of monkeypox will be key to improving the capacity of GPs to respond to human monkeypox cases and to report into a disease surveillance system.

The current re-emergence of human monkeypox (HMPX) is a global concern for endemic and non-endemic countries, but healthcare workers in some regions, like Asia, have less experience with identifying and treating HMPX cases. This study aimed to assess the confidence and its predictors in HMPX case management among general practitioners (GPs), the frontline doctors in Indonesia, and to explore their perspectives on HMPX. Between May and July 2019, GPs in Indonesia completed an online-based survey. The questionnaire collected information on GPs' confidence, perspective, sociodemographic, workplace and professional characteristics, exposure to HMPX information and knowledge on HMPX. A logistic regression analysis was employed to explore the explanatory variables influencing the confidence and the perspective. We included 395 GPs in our analysis (77.4% out of 510 responses received) of which 10.1% and 34.9% were classified having good confidence using an 80% and 70% cut-off for confidence score, respectively. In the adjusted analysis, receiving information about HMPX during medical training was the only variable significantly associated with good confidence (adjusted odds ratio 2.74, 95% confidence interval 1.57 to 4.78 and p < 0.001). Approximately 73.6% and 77.9% of GPs agreed that HMPX is an important infectious disease and it has potential to detrimentally impact the Indonesian economy, respectively. In addition, 88.8% of GPs suggested that the disease should be incorporated into the National Medical Curriculum of Indonesia. In conclusion, in case of HMPX outbreak, majority of the GPs in Indonesia seem to be less confident in diagnosing and treating cases, using their current knowledge, skills and their workplace facilities. Therefore, a systematic strategy to improve their confidence in managing HMPX is required.

BACKGROUND: A clinical trial is ongoing to evaluate the safety and efficacy of a monkeypox vaccine among healthcare workers (HCWs). The critical question that needs to be addressed is whether HCWs are willing to accept and purchase this vaccine. The objective of this study was to evaluate the acceptance and willingness to pay (WTP) for the vaccine among HCWs. METHODS: From May to July 2019, a cross-sectional study was conducted among registered general practitioners (GPs) in Indonesia. A contingent valuation method was employed to evaluate the WTP. Besides acceptance and WTP, various explanatory variables were also collected and assessed. A logistic regression and a multivariable linear regression were used to explore the explanatory variables influencing acceptance and WTP, respectively. RESULTS: Among 407 respondents, 391 (96.0%) expressed acceptance of a free vaccination. The mean and median WTP was US$ 37.0(95%CI:US$ 32.76-US$ 41.23) and US$ 17.90(95%CI:US$ 17.90-US$ 17.90), respectively. In an unadjusted analysis, those 30 years old or younger had 2.94 times greater odds of vaccine acceptance compared to those who were older (95%CI: 1.07-8.08). Location of alma mater, type of workplace, length of individual medical experience, and monthly income of GPs were all significantly associated with WTP. CONCLUSION: Although the vast majority of GPs would accept a freely provided vaccine, they were also somewhat price sensitive. This finding indicates that partial subsidy maybe required to achieve high vaccine coverage, particularly among GPs at community health centres or those with a shorter duration of medical practice.
