Researchers report one method to help combat anti-vaccine information and reduce vaccine hesitancy is to introduce those with negative views about immunizations to someone who has suffered a vaccine-preventable disease. The study reports 70% of students who were exposed to someone with a vaccine-preventable disease moved from vaccine hesitancy to pro-vaccine. Overall, 75% of those who were anti-vaccine increased their vaccine attitude scores, with 50% moving to a pro-vaccine stance.
