Dr. Robert Sapolsky has been researching a "stress vaccine" for 30 years, and one may very well be one on the horizon.
Dr. Sapolsky believes that it is possible to alter brain chemistry to create a state of 'focused calm,' and claims that he is closing in on a path to a genetically engineered formula.
He has adapted a herpes virus to carry engineered "neuroprotective" genes deep into your brain to neutralize stress hormones.
According to Blue Star Chronicles:
"Unfortunately, we'll have to wait for all the trials to be completed. In the meantime, we'll have to rely on stress-reduction techniques we already use like yoga, exercise and for some, medication."
