Factors Associated with Vaccination Intention against the COVID-19 Pandemic: A Global Population-Based Study

Abstract

Several vaccines have been developed for COVID-19 since the pandemic began. This study aimed to evaluate the factors associated with COVID-19 vaccination intention. A global survey was conducted across 26 countries from October, 2020 to December, 2021 using an online self-administered questionnaire. Demographic information, socio-economic status, and clinical information were collected. A logistic regression examined the associations between vaccine intention and factors such as perceptions and the presence of chronic physical and mental conditions. The sample included 2459 participants, with 384 participants (15.7%) expressing lower COVID-19 vaccination intent. Individuals who identified as female; belonged to an older age group; had a higher level of education; were students; had full health insurance coverage; or had a previous history of influenza vaccination were more willing to receive vaccination. Conversely, those who were working part-time, were self-employed, or were receiving social welfare were less likely to report an intention to get vaccinated. Participants with mental or physical health conditions were more unwilling to receive vaccination, especially those with sickle cell disease, cancer history within the past five years, or mental illness. Stronger vaccination intent was associated with recommendations from the government or family doctors. The presence of chronic conditions was associated with lower vaccine intention. Individuals with health conditions are especially vulnerable to health complications and may experience an increased severity of COVID-19 symptoms. Future research should evaluate the effectiveness of interventions targeting the vaccine perceptions and behaviours of at-risk groups. As such, public awareness campaigns conducted by the government and proactive endorsement from health physicians may help improve COVID-19 vaccination intention.

Factors Associated with Vaccination Uptake among Young Children: A Follow-Up Study of 1799 Toddlers

“…Therefore, it is suggested that the government should provide ample information on vaccines to the general public. It is also recommended that vaccination centers be set up in more convenient locations with later service hours to address the difficulty of making time for getting children vaccinated after the long working hours of the parents [ 45 ].…”

Vaccination status and attitudes towards COVID-19 vaccination in patients undergoing active cancer treatment in a referral center in Mexico: a survey study

“…Therefore, patients with cancer undergoing active cancer treatment in our center appear to be less reluctant to COVID-19 vaccination than expected. Patients with cancer have been described to be more hesitant to undergo COVID-19 vaccination, as demonstrated by a global population-based study exploring factors associated with vaccination intention against COVID-19, which showed that more patients with a history of cancer in the past 5 years were unwilling to receive vaccination against COVID-19 (61%) vs those without a history of cancer (14%) [22]. A meta-analysis on COVID-19 vaccine acceptance and hesitancy among patients with cancer, including 29 studies, found a pooled prevalence of vaccine acceptance of 59% and a pooled prevalence of vaccine hesitancy due to fear of vaccine-related side-effects of 53% [11].…”

Sociodemographic Factors Associated with COVID-19 Vaccination among People in Guatemalan Municipalities

“…Prior studies have largely focused on factors related to the intent to vaccinate rather than the completion of COVID-19 vaccination. A 2022 global, population-based analysis noted that participants identifying as female, in older age groups, with a higher level of education, and with health insurance reported being more willing to get vaccinated [32]. In a study of Latin American and Caribbean countries, those with a university education, residence in an urban area, and a higher perceived likelihood of contracting COVID-19 had higher intentions to be vaccinated [31].…”

“…Municipalities are organized into 22 departments, and some variables only available at the departmental level were obtained through the 2014-2015 Demographic and Health Survey [29]. We chose sociodemographic variables a priori that could be proxies for healthcare access, poverty, and related variables that we hypothesized to be related to vaccination uptake [30][31][32]. We elected to use the general poverty indicator (percentage of each municipality population experiencing poverty) developed by Figueroa Chávez and colleagues and shared with our team [33].…”
