Which factor can contribute to vaccine hesitancy?

• A. Trust in scientific information
• B. Access barriers and misinformation
• C. High confidence in vaccines
• D. Clear communication from health authorities

Answer: (B)

Vaccine hesitancy grows when practical barriers to getting vaccinated and exposure to misinformation hinder people from moving forward with vaccination. If obtaining a shot is inconvenient—long travel, transportation challenges, work or childcare conflicts, or out-of-pocket costs—people may delay or skip vaccination even when they’re open to it in principle. At the same time, misinformation can sow doubts about safety, effectiveness, or the need for the vaccine, leading to indecision or refusal. These factors directly affect both the ability to access vaccines and the beliefs people hold about them, increasing hesitancy. By contrast, reliable information from trusted sources, genuine confidence in vaccines, and clear guidance from health authorities tend to support acceptance and reduce hesitancy.
