Various factors contribute to vaccine hesitancy, including misinformation, cultural beliefs, fear of side effects, and lack of trust in healthcare providers or government agencies. Misinformation often spreads rapidly through social media, leading to widespread misconceptions about vaccines. Cultural beliefs and traditions can also play a role, as some communities may have long-standing practices or religious views that discourage vaccination. Additionally, some individuals may fear potential side effects, even if they are rare, and others may distrust the intentions of healthcare providers or government agencies.
