OBJECTIVES:

The decision-making process for taking vaccination is influenced by a multitude of factors such as individual beliefs concerning vaccinations, trust in contextual forces, and sociodemographic. This study established a model to understand the relationship between people’s beliefs in the safety, importance and effectiveness of vaccines, their trust in the medical advice from the government and doctors and their behaviors of having their children vaccinated from infectious diseases in low-and-middle-income countries (LMIC).

METHODS:

We structured a structural equation model with two latent variables, Motivation and Trust, and their relationships with the vaccination taking behavior. Motivation is constructed by people’s beliefs in the safety, importance and effectiveness of vaccines and trust is constructed by people’s trust in government, medical providers and scientists. This study used the 2018 Wellcome Global Monitor dataset and focused on people in 80 LMIC. The countries were divided into eight geographic regions: Eastern Africa, Central & Southern Africa, Norther Africa & Middle East, Western Africa, Central Asia, Southeast Asia, South Asia and Southern& Eastern Europe.

RESULTS:

The latent variable Motivation is significantly positively associated with parental vaccination behaviors in all geographic areas except for South Asia and Western Africa. South Asia is the only area where the trust in government and medical system, providers had a significant association with vaccination behavior and such association is positive.

CONCLUSIONS:

In most LMIC, positive attitudes about vaccines are associated with an improved vaccine rate. Increasing people’s belief in vaccines’ importance, safety and effectiveness will be essential both for boosting vaccination rates and scaling up a vaccine for COVID-19. In South Asia, trust in the government and the public health system are important in deciding taking vaccines. In these countries, policymakers need to think of ways to improve people’s trust in the public health system and further effectively communicate important health messages.
