Positive thinking could boost immune response to vaccines, say scientists
People picturing positive experiences found to produce more antibodies, hinting at future clinical potential
TL;DR
- Positive thinking may boost the immune system, particularly in response to vaccination.
- Healthy volunteers who used mental strategies to boost activity in the brain's ventral tegmental area (VTA) showed a stronger immune response to a hepatitis B vaccine.
- The most successful mental strategy involved positive expectations or imagining good things happening.
- This research is the first demonstration in humans suggesting that recruiting the brain's reward system can increase immunization effectiveness.
- While promising, larger trials are necessary to confirm any clear medical benefits and to understand if other parts of the immune system are affected.
- The approach is intended as a complementary tool to enhance immune responsiveness and not as a replacement for vaccines or standard medical care.
