    Abstract Improved uptake of adult vaccinations could substantially reduce the burden of infectious disease worldwide, however very few countries achieve high coverage of recommended adult vaccinations. Vaccine hesitancy is an important driver of low vaccine uptake among adults but no measure currently exists to capture general vaccination attitudes in this population accurately and efficiently. We utilize data from two surveys of adult vaccine attitudes and uptake conducted in fifteen countries to evaluate the Vaccination Trust Indicator (VTI). The VTI is a six-item measure intended to capture general vaccine attitudes. We utilized multivariable logistic regression to examine the association between VTI scores and self-reported receipt of the seasonal influenza vaccine, receipt of a tetanus toxoid-containing vaccine and intent to receive the flu vaccine in the next season. In the five countries with self-reported vaccine receipt data, we found that a ten-point increase in VTI score was associated with a 50% increase in odds of influenza vaccine receipt (OR = 1.55, 95% CI = 1.48, 1.62) and 25% increase in the odds of tetanus vaccine receipt (OR = 1.26, 95% CI = 1.21, 1.30). Strong associations between VTI score and vaccine receipt were found in each country except China. A strong association between VTI score and intent to receive the influenza vaccine was found in all fifteen countries. The VTI is a promising tool for assessing adult immunization attitudes with clear and immediate uses for immunization programs globally.

    Abstract In 2020, 26 million refugees resettled in a new country-fleeing their homes due to conflict and persecution. Due to low immunization coverage and underlying health conditions, refugees commonly face an increased risk of contracting vaccine-preventable diseases. We collected and analyzed existing routine immunization policies for refugees across 20 low- and middle-income countries (LMICs) and 20 high-income countries (HICs), each with the highest number of refugees per 1000 residents. Primary and secondary data sources were used to collect policy evidence. Across 20 LMICs, 13 countries specified standing nationwide routine immunization policies for refugees, while 14 out of the 20 HICs included refugees in their national routine immunization programs. LMICs and HICs should include refugees in their national routine immunization policies and provide accessible and affordable immunizations. Such efforts would reduce vaccine-preventable diseases and protect the health of refugee populations-especially during the COVID-19 pandemic.

    Abstract Amidst an unprecedented Monkeypox outbreak, we aimed to measure knowledge, attitudes, practices and Monkeypox vaccination intentions among the U.S. adult population. We conducted an online cross-sectional survey, representative of the U.S. adult general public in June 2022. We asked participants whether they would receive a Monkeypox vaccine, if they were recommended to do so. Participants also answered questions on their self-assessed level of Monkeypox knowledge, risk perception, perceived exaggeration of the threat, and self-efficacy around Monkeypox. Furthermore, we asked about their trusted sources of information, COVID-19 vaccination status and administered the 6-item Vaccine Trust Indicator (VTI). Survey weights were created based on age, gender and race. We analyzed predictors of Monkeypox vaccination intentions using logistic regression, adjusted for education, age, race and ethnicity. A total of 856 respondents completed the survey, of which 51% (n = 436) were female and 41% (n = 348) had a college degree or higher. If recommended, 46% of respondents intended to get vaccinated against Monkeypox, 29% would not get vaccinated and 25% did not know. Almost half the respondents (47%) found their own knowledge level about Monkeypox poor or very poor. The most trusted sources of information about the outbreak were healthcare professionals and officials, but also known doctors and researchers with a large online following. Only 24% indicated that the U.S. Centers for Disease Control and Prevention should be in charge of the outbreak response. Being vaccinated against COVID-19 was a strong predictor of intention to receive a Monkeypox if recommended (adjusted Odds Ratio (aOR) 29.2, 95% Confidence Interval (CI) 13.1-65.3). Increased risk perception was positively associated with vaccination intentions (aOR 2.6, 95% CI 1.8-3.6), scoring high on the VTI as well (5.4, 95% CI (3.2-9.1). The low levels of self-assessed knowledge, vaccination intentions and influence of COVID-19 vaccination status point to a lack of clear communication.
