Positive Thinking Might Boost Your Immune System’s Responses to Vaccines, New Research Suggests

Researchers found an association between increased activity in a reward region of the brain—primarily stimulated by hopeful thinking—and heightened levels of protective antibodies after receiving a vaccine

Many public health experts, immunologists and pediatricians criticized the revised childhood vaccine schedule, arguing that the changes will likely lead to more disease outbreaks.

U.S. Overhauls Immunization Schedule for Kids, Removing Recommendations for Vaccines Against the Flu, RSV and More
