Hesitancy Toward a COVID-19 Vaccine

Area of Science:

• Public Health
• Vaccinology
• Health Communication

Background:

• Global efforts focus on combating COVID-19, with vaccine development being crucial.
• Vaccine success hinges on population uptake, necessitating an understanding of public intentions.
• COVID-19 vaccine hesitancy presents a significant challenge to achieving herd immunity.

Purpose of the Study:

• To assess COVID-19 vaccine intentions among a representative US adult sample.
• To identify factors influencing vaccine uptake, including perceived risk and information source.
• To understand the primary drivers of vaccine hesitancy for COVID-19.

Main Methods:

• A survey experiment was conducted with 3,133 US adults.
• Participants' intentions to vaccinate themselves and their children were recorded.
• Experimental factors included stated COVID-19 severity, infectiousness, and risk information source (White House vs. CDC).

Main Results:

• 20% of US adults expressed intent to decline the COVID-19 vaccine.
• COVID-19 severity did not significantly impact vaccine intentions.
• Coronavirus infectiousness influenced intentions; inconsistent risk messages decreased uptake.
• Distrust in vaccine safety and general vaccine avoidance (e.g., no flu shot) were key determinants of hesitancy.

Conclusions:

• A significant portion of the US population intends to forgo COVID-19 vaccination.
• Effective risk communication and addressing safety concerns are vital for vaccine promotion.
• Pre-existing vaccine avoidance behaviors are strong predictors of COVID-19 vaccine hesitancy.
